SIP is a text based protocol and the module provides a large set of very useful functions to manipulate the message at text level, e.g., regular expression search and replace, Perl-like substitutions, etc.
Note: all SIP-aware functions like insert_hf, append_hf or codec operations have been moved to the sipmsgops module.
The following modules must be loaded before this module:
No dependencies on other OpenSIPS modules.
Searches for the re in the message.
Meaning of the parameters is as follows:
re - Regular expression.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Searches for the re in the body of the message.
Meaning of the parameters is as follows:
re - Regular expression.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Searches for the first match of re and appends txt after it.
Meaning of the parameters is as follows:
re - Regular expression.
txt - String to be appended.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Searches for the first match of re in the body of the message and appends txt after it.
Meaning of the parameters is as follows:
re - Regular expression.
txt - String to be appended.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Replaces the first occurrence of re with txt.
Meaning of the parameters is as follows:
re - Regular expression.
txt - String.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Replaces the first occurrence of re in the body of the message with txt.
Meaning of the parameters is as follows:
re - Regular expression.
txt - String.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Replaces all occurrence of re with txt.
Meaning of the parameters is as follows:
re - Regular expression.
txt - String.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Replaces all occurrence of re in the body of the message with txt. Matching is done on a per-line basis.
Meaning of the parameters is as follows:
re - Regular expression.
txt - String.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Replaces all occurrence of re in the body of the message with txt. Matching is done over the whole body.
Meaning of the parameters is as follows:
re - Regular expression.
txt - String.
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Example 1.9. replace_body_atonce usage
...
# strip the whole body from the message:
if(has_body() && replace_body_atonce("^.+$", ""))
remove_hf("Content-Type");
...
Replaces re with repl (sed or perl like).
Meaning of the parameters is as follows:
'/re/repl/flags' - sed like regular expression. flags can be a combination of i (case insensitive), g (global) or s (match newline don't treat it as end of line).
're' - is regular expression
'repl' - is replacement string - may contain pseudo-variables
'flags' - substitution flags (i - ignore case, g - global)
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Example 1.10. subst usage
...
# replace the uri in to: with the message uri (just an example)
if ( subst('/^To:(.*)sip:[^@]*@[a-zA-Z0-9.]+(.*)$/t:\1\u\2/ig') ) {};
# replace the uri in to: with the value of avp sip_address (just an example)
if ( subst('/^To:(.*)sip:[^@]*@[a-zA-Z0-9.]+(.*)$/t:\1$avp(sip_address)\2/ig') ) {};
...
Runs the re substitution on the message uri (like subst but works only on the uri)
Meaning of the parameters is as follows:
'/re/repl/flags' - sed like regular expression. flags can be a combination of i (case insensitive), g (global) or s (match newline don't treat it as end of line).
're' - is regular expression
'repl' - is replacement string - may contain pseudo-variables
'flags' - substitution flags (i - ignore case, g - global)
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Example 1.11. subst_uri usage
...
# adds 3463 prefix to numeric uris, and save the original uri (\0 match)
# as a parameter: orig_uri (just an example)
if (subst_uri('/^sip:([0-9]+)@(.*)$/sip:3463\1@\2;orig_uri=\0/i')){$
# adds the avp 'uri_prefix' as prefix to numeric uris, and save the original
# uri (\0 match) as a parameter: orig_uri (just an example)
if (subst_uri('/^sip:([0-9]+)@(.*)$/sip:$avp(uri_prefix)\1@\2;orig_uri=\0/i')){$
...
Runs the re substitution on the message uri (like subst_uri but works only on the user portion of the uri)
Meaning of the parameters is as follows:
'/re/repl/flags' - sed like regular expression. flags can be a combination of i (case insensitive), g (global) or s (match newline don't treat it as end of line).
're' - is regular expression
'repl' - is replacement string - may contain pseudo-variables
'flags' - substitution flags (i - ignore case, g - global)
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Example 1.12. subst usage
...
# adds 3463 prefix to uris ending with 3642 (just an example)
if (subst_user('/3642$/36423463/')){$
...
# adds avp 'user_prefix' as prefix to username in r-uri ending with 3642
if (subst_user('/(.*)3642$/$avp(user_prefix)\13642/')){$
...
Replaces re with repl (sed or perl like) in the body of the message.
Meaning of the parameters is as follows:
'/re/repl/flags' - sed like regular expression. flags can be a combination of i (case insensitive), g (global) or s (match newline don't treat it as end of line).
're' - is regular expression
'repl' - is replacement string - may contain pseudo-variables
'flags' - substitution flags (i - ignore case, g - global)
This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
