aaa_url parameterThe ACC module is used to account transaction information to different backends such as syslog, SQL, AAA.
To account a transaction and to choose which set of backends to be used, the script writer only has to mark the transaction for accounting by using the do_accounting() script function. Note that the function is not actually doing the accounting at that very time, it is just setting a marker - the actual accounting will be done later when the transaction or dialog will be completed.
Even so, the module allows the script writer to force accounting on the spot in special cases via some other script functions.
The accounting module will log by default a fixed set of attributes for the transaction - if you customize your accounting by adding more information to be logged, please see the next chapter about extra accounting - Section 1.2, “Extra accounting”.
The fixed minimal accounting information is:
Request Method name
From header TAG parameter
To header TAG parameter
Call-Id
3-digit Status code from final reply
Reason phrase from final reply
Timestamp when transaction was completed
If a value is not present in the request, the empty string is accounted instead.
Note that:
A single INVITE may produce multiple accounting reports -- that's most likely due to the SIP forking feature.
Since version 2.2, all flags used for accounting have been replaced with the do_accounting() function. No need to worry anymore whether you have set the flags or not, or be confused by various flag names, now you only have to call the function and it will do all the work for you.
OpenSIPS now supports session/dialog accounting. It can automatically correlate INVITEs with BYEs for generating proper CDRs, for example for billing purposes.
If a UA fails in the middle of a conversation, a proxy will never find out about it. In general, a better practice is to account from an end-device (such as PSTN gateway), which best knows about call status (including media status and PSTN status in case of the gateway).
The SQL, Event Interface and AAA backend support are compiled in the module.
A very comprehensive description of how the accounting module works in terms accounting scope, accounting events and accounting backends can be found in this online Advanced Accounting Tutorial.
loadmodule "modules/acc/acc.so"
if ($ru=~"sip:+40") /* calls to Romania */ {
if (!proxy_authorize("sip_domain.net" /* realm */,
"subscriber" /* table name */)) {
proxy_challenge("sip_domain.net" /* realm */, "0" /* no qop */ );
exit;
}
if (is_method("INVITE") && !db_check_from()) {
xlog("FROM URI != digest username\n");
sl_send_reply("403","Forbidden");
}
do_accounting("log"); /* set for accounting via syslog */
t_relay(); /* enter stateful mode now */
};
Along the static default information, the ACC module allows dynamic selection of extra information to be logged using the acc_extra pseudovariable. This allows you to log any pseudo-variable (AVPs, parts of the request, parts of the reply, etc).
Selection of extra information is done via extra_field parameter by specifying tags and log_names for the additional information. This information is defined via acc_extra pseudovariable, referenced with the define tag. If the tag is not specified, its value will be considered to be the same as the log_value. Accounting backend(log, db, aaa, evi) is specified at the beginning of the definition, separated by ':' from the rest. The syntax of the parameter is:
backend : tag -> log_name (';'tag -> log_name)*
backend : tag (';' tag)*
Extra values are consistent during the whole call. Setting a value during a request, will cause it to remain visible during all replies. Also, concerning CDR logging, setting a value on the initial INVITE will result in having that value throughout the dialog.
Via log_name you define how/where the data will be logged. Its meaning depends of the accounting support which is used:
LOG accounting - log_name will be just printed along with the data in log_name=data format;
DB accounting - log_name will be the name of the DB column where the data will be stored.IMPORTANT: add in db acc table the columns corresponding to each extra data;
AAA accounting - log_name will be the AVP name used for packing the data into AAA message. The log_name will be translated to AVP number via the dictionary. IMPORTANT: add in AAA dictionary the log_name attribute.
Events accounting - log_name will be the name of the parameter in the event raised.
Declaring an extra in the format of
modparam("acc", "extra_fields", "log: a -> test_a")
will enable you to set the value for test_a field of the log only by setting $acc_extra(a) variable. Otherwise, the field shall be logged with no value(null).
A SIP call can have multiple legs due forwarding actions. For example user A calls user B which forwards the call to user C. There is only one SIP call but with 2 legs ( A to B and B to C). Accounting the legs of a call is required for proper billing of the calls (if C is a PSTN number and the call is billed, user B must pay for the call - as last party modifing the call destination-, and not A - as initiator of the call. Call forwarding on server is only one example which shows the necessity of the having an accounting engine with multiple legs support.
First how it works: The idea is to have a variable to store a set of values for each leg. The meaning of the variable content is strictly decided by the script writer - it can be the origin and source of the leg, its status or any other related information. By default there is defined only one leg. Script writer has to decide when is the time to create a new leg, by using acc_new_leg() script function. When creating a new leg, all the values for that leg will be set to NULL by default.
When the accounting information for the call will be written/sent, all the call-leg pairs will be added.
By default, the multiple call-leg support is disabled - it can be
enabled just by setting acc_leg variable
leg_fields module parameter. Note that
the last one only makes sense only for CDRs that are generated
automatically by OpenSIPS.
For each call, all the values from the acc_leg variable will be logged. How the information will be actually logged, depends of the data backend:
syslog -- all leg-sets will be added to one record string as acc_leg(leg1)=xxx, acc_leg(leg2)=xxxx ,... sets.
database -- each pair will be separately logged (due DB data structure constraints); several records will be written, the difference between them being only the fields corresponding to the call-leg info.
You will need to add in your DB (all acc related tables) the colums for call-leg info (a column for each leg value of the set).
AAA -- all sets will be added to the same AAA accounting message as AAA AVPs - for each call-leg a set of AAA AVPs will be added (corresponding to the per-leg set)
You will need to add in your dictionary the AAA AVPs used in call-leg set definition.
events -- each pair will appear as a different parameter-value pair in the event. Similar to the database behavior, multiple events will be raised, and the only difference between them is the leg information.
Important!!! In order to use RADIUS, one must include the AVPs which are located in $(opensips_install_dir)/etc/dictionary.opensips, both in opensips radius config script dictionary and radius server dictionary. Most important are the last three AVPs (IDs : 227, 228, 229) which you won't find in any SIP dictionary (at least at this moment) because they are only used in openSips.
ACC module can now also maintain session/dialog accounting. This allows you to log useful information like call duration, call start time and setup time.
In order to have CDRs accounting, first you need to set the cdr flag when calling do_accounting() script function for the initial INVITE of the dialog.
This type of accounting is based on the dialog module. When an initial INVITE is received, if the cdr flag is set, then the dialog creation time is saved. Once the call is answered and the ACK is received, other information like extra values or leg values are saved. When the corresponding BYE is received, the call duration is computed and all information is stored to the desired backend.
The module depends on the following modules (in the other words the listed modules must be loaded before this module):
tm -- Transaction Manager
a database module -- If SQL support is used.
rr -- Record Route, if “detect_direction” module parameter is enabled.
an aaa module
dialog -- Dialog, if “cdr” option is used
Should be early media (any provisional reply with body) accounted too ?
Default value is 0 (no).
By default, CANCEL reporting is disabled -- most accounting applications wants to see INVITE's cancellation status. Turn on if you explicitly want to account CANCEL transactions.
Default value is 0 (no).
Controls the direction detection for sequential requests. If enabled (non zero value), for sequential requests with upstream direction (from callee to caller), the FROM and TO will be swapped (the direction will be preserved as in the original request).
It affects all values related to TO and FROM headers (body, URI, username, domain, TAG).
Default value is 0 (disabled).
Defines the tag-log_value set to be used in extra fields accounting. See Section 1.2, “Extra accounting” for a detailed description of the Extra accounting.
If empty, extra accounting support will be disabled.
Default value is 0 (disabled).
Example 1.4. Setting extra_fields example:
# for syslog-based accounting, use any text you want to be printed
# if setting $acc_extra(a) you will see "My_a_Field=<value> in logs
# if setting $acc_extra(b) you will see "b=<value> in logs
modparam("acc", "extra_fields", "log: a->My_a_Field; b")
# for mysql-based accounting, use the names of the columns
# $acc_extra(a) = <value> results in setting col_a with <value> in db
modparam("acc", "extra_fields", "db: a->col_a; col_b")
# for AAA-based accounting, use the names of the AAA AVPs
modparam("acc", "extra_fields","aaa:a->AAA_SRC;b->AAA_DST")
# evi definition example
modparam("acc", "extra_fields","a->2345;b->2346")
Defines the tag-log_value set to be used in multi-leg accounting. See Section 1.3, “Multi Call-Legs accounting” for a detailed description of the Multi Call-Legs accounting.
If empty, multi-leg accounting support will be disabled.
Default value is 0 (disabled).
Example 1.5. Setting leg_fields example:
# for syslog-based accounting, use any text you want to be printed
# if setting $(acc_leg(a)[0]) you will see "My_a_Field=<value> in logs
# if setting $(acc_leg(b)[0]) you will see "b=<value> in logs
modparam("acc", "leg_fields", "log: a->My_a_Field; b")
# for mysql-based accounting, use the names of the columns
# $acc_leg(a) = <value> results in setting col_a with <value> in db
modparam("acc", "leg_fields", "db: a->col_a; col_b")
# for AAA-based accounting, use the names of the AAA AVPs
modparam("acc", "leg_fields","aaa:a->AAA_LEG_SRC;b->AAA_LEG_DST")
# evi definition example
modparam("acc", "leg_fields","a->2345;b->2346")
Log level at which accounting messages are issued to syslog.
Default value is L_NOTICE.
Log facility to which accounting messages are issued to syslog. This allows to easily seperate the accounting specific logging from the other log messages.
Default value is LOG_DAEMON.
This is the url representing the AAA protocol used and the location of the configuration file of this protocol.
If the parameter is set to empty string, the AAA accounting support will be disabled.
Default value is “NULL”.
Example 1.8. Set aaa_url parameter
...
modparam("acc", "aaa_url", "radius:/etc/radiusclient-ng/radiusclient.conf")
...
AAA service type used for accounting.
Default value is not-set.
Example 1.9. service_type example
# Default value of service type for SIP is 15
modparam("acc", "service_type", 15)
Table name of accounting successful calls -- database specific.
Default value is “acc”
Table name for accounting missed calls -- database specific.
Default value is “missed_calls”
SQL address -- database specific. If is set to NULL or empty string, the SQL support is disabled.
Default value is “NULL” (SQL disabled).
Column name in accounting table to store the request's method name as string.
Default value is “method”.
Column name in accounting table to store the From header TAG parameter.
Default value is “from_tag”.
Column name in accounting table to store the To header TAG parameter.
Default value is “to_tag”.
Column name in accounting table to store the request's Callid value.
Default value is “callid”.
Column name in accounting table to store the final reply's numeric code value in string format.
Default value is “sip_code”.
Column name in accounting table to store the final reply's reason phrase value.
Default value is “sip_reason”.
Column name in accounting table to store the time stamp of the transaction completion in date-time format.
Default value is “time”.
This variable can addresed with the tag names defined using extra_fields. If do_accounting() isn't called, this variable is visible during the whole processing of one message, enabling calling acc_XXX_request(). If do_accounting() is called, the variable will be visible from the first call of this function until the actual accounting is being made.
This variable can be addressed with the tag names defined using leg_fields and a valid leg index (<= $acc_current_leg). This variable cannot be used unless do_accounting() is used. The variable also accepts negative indexes, which start from -1 (the lastly added leg).
# the "caller" value of the current leg
$acc_leg(caller)
# the "caller" value of the lastly added leg
$(acc_leg(caller)[-1]) # equivalent to $acc_leg(caller)
# equivalent to $(acc_leg(caller)[$acc_current_leg])
# the "caller" value of the next-to-last leg
$(acc_leg(caller)[-2])
Holds the index of the current leg, starting from 0. Calling acc_new_leg() will increment this index.
do_accounting() replaces all the
*_flag and, *_missed_flag, cdr_flag, failed transaction_flag and the
db_table_avp modparams. Just call do_accounting(), select where and how you want
the accounting to take place, and the function will do all the work for you.
Meaning of the parameters is as follows:
type - the type of accounting you want to do. All types have to be separated by '|'. The following parameters can be used:
log - syslog accounting;
db - database accounting;
aaa - aaa specific accounting;
evi - Event Interface accounting;
flags - flags for the accounting type you have selected. All the types have to be separated by '|'. The following parameters can be used:
cdr - enables dialog-level accounting. OpenSIPS will internally detect dialog termination (generation/receipt of a BYE request), and store the CDR as soon as the BYE request is replied to. By enabling the "cdr" flag, the following additional fields will be populated: duration, ms_duration, setuptime, created. (requires dialog module support)
missed - log missed calls; take care that this flag will be deactivated after the first missed call; you will have to reactivate it in the failure_route if you want to account each destination that did not respond to the call;
failed - flag which indicates if the transaction should also be accounted in case of failure (status>=300);
table - table where to do the accounting; it replaces old table_avp parameter;
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE and LOCAL_ROUTE.
Example 1.21. do_accounting usage
...
if (!has_totag()) {
if (is_method("INVITE")) {
/* enable cdr and missed calls accounting in the database
* and to syslog; db accounting shall be done in "my_acc" table */
do_accounting("db|log", "cdr|missed", "my_acc");
}
}
...
if (is_method("BYE")) {
/* do normal accounting via aaa */
do_accounting("aaa");
}
...
drop_accounting() resets flags
and types of accounting set with do_accounting(). If called with no
arguments all accounting will be stopped. If called with only one argument
all accounting for that type will be stopped. If called with two arguments
normal accounting will still be enabled.
Meaning of the parameters is as follows:
type - the type of accounting you want to stop. All the types have to be separated by '|'. The following parameters can be used:
log - stop syslog accounting;
db - stop database accounting;
aaa - stop aaa specific accounting;
evi - stop Event Interface accounting;
flags - flags to be reset for the accouting type you have selected. All the types have to be separated by '|'. The following parameters can be used:
cdr - stop CDR accounting;
missed - stop logging missed calls;
failed - stop failed transaction accounting;
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE and LOCAL_ROUTE.
Example 1.22. drop_accounting usage
...
acc_log_request("403 Destination not allowed");
if (!has_totag()) {
if (is_method("INVITE")) {
/* enable cdr and missed calls accounting in the database
* and to syslog; db accounting shall be done in "my_acc" table */
do_accounting("db|log", "cdr|missed", "my_acc");
}
}
...
/* later in your script */
if (...) { /* you don't want accounting anymore */
/* stop all syslog accounting */
drop_accounting("log");
/* or stop missed calls and cdr accounting for syslog;
* normal accounting will still be enabled */
drop_accounting("log","missed|cdr");
/* or stop all types of accounting */
drop_accounting();
}
...
acc_request reports on a request,
for example, it can be used to report on missed calls to off-line users
who are replied 404 - Not Found. To avoid multiple reports on UDP
request retransmission, you would need to embed the
action in stateful processing.
Meaning of the parameters is as follows:
comment - Comment describing how the request completed - this string has to contain a reply code followed by a reply reason phrase (ex: "404 Nobody home"). Variables are accepted in this string.
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE and LOCAL_ROUTE.
Like acc_log_request,
acc_db_request reports on a
request. The report is sent to database at “db_url”, in
the table referred to in the second action parameter.
Meaning of the parameters is as follows:
comment - Comment describing how the request completed - this string has to contain a reply code followed by a reply reason phrase (ex: "404 Nobody home"). Variables are accepted in this string.
table - Database table to be used.
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE and LOCAL_ROUTE.
Example 1.24. acc_db_request usage
...
acc_db_request("Some comment", "Some table");
acc_db_request("$T_reply_code $(<reply>rr)","acc");
...
Like acc_log_request,
acc_aaa_request reports on
a request. It reports to aaa server as configured in
“aaa_url”.
Meaning of the parameters is as follows:
comment - Comment describing how the request completed - this string has to contain a reply code followed by a reply reason phrase (ex: "404 Nobody home"). Variables are accepted in this string.
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE and LOCAL_ROUTE.
Like acc_log_request,
acc_evi_request reports on a
request. The report is packed as an event sent through the OpenSIPS Event
Interface as E_ACC_EVENT if the reply code is a
positive one (lower than 300), or E_ACC_MISSED_EVENT
for negative or no codes. More information on this in
Exported Events.
Meaning of the parameters is as follows:
comment - Comment describing how the request completed - this string has to contain a reply code followed by a reply reason phrase (ex: "404 Nobody home"). Variables are accepted in this string.
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE and LOCAL_ROUTE.
Creates a new leg and increments $acc_current_leg only if multi-leg accounting is used. All values of the new leg will be initialized to null.
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE and LOCAL_ROUTE.
The event raised when a CDR is generated. Note that this event will only be triggered if the auto CDR accounting is used.
Parameters:

2.1. | What happened with old report_ack parameter |
The parameter is considered obsolete. It was removed as acc module is doing SIP transaction based accouting and according to SIP RFC, end2end ACKs are a different transaction (still part of the same dialog). ACKs can be individually accouted as any other sequential (in-dialog) request. | |
2.2. | What happened with old log_fmt parameter |
The parameter became obsolete with the restructure of the data logged by ACC module (refer to the Overview chapter). For similar behaviour you can use the extra accouting (see the corresponding chapter). | |
2.3. | What happened with old multi_leg_enabled parameter |
The parameter became obsolete by the addition of the new multi_leg_info parameter. The multi-leg accouting is automatically enabled when multi_leg_info is defined. | |
2.4. | What happened with old src_leg_avp_id and dst_leg_avp_id parameters |
The parameter was replaced by the more generic new parameter multi_leg_info. This allows logging (per-leg) of more information than just dst and src. | |
2.5. | Where can I find more about OpenSIPS? |
Take a look at https://opensips.org/. | |
