[OpenSIPS-Users] Need some clarification if I have gateways with tls socket then how does the failover will work

[Sasmita Panda]

Hi All ,

I have opensips running on instance '10.78.1.1' . I have configured tls on
the config .
Below is my dr_gatewas and dr_carriers table .

dr_gateways :
|  4 | gw2        |    3 | 1.1.1.1:5065                |     0 | NULL
| NULL  |          0 |     0 | tls:10.78.1.1:5061 | NULL        |
|  6 | gw3        |    3 | 2.2.2.2:5067               |     0 | NULL
| NULL  |          0 |     0 | tls:10.78.1.1:5061 | NULL        |


dr_carriers;
+----+-----------+--------+-------+----------+-------+-------+-------------+
| id | carrierid | gwlist | flags | sort_alg | state | attrs | description |
+----+-----------+--------+-------+----------+-------+-------+-------------+
|  1 | cr1       | gw2    |     3 | N        |     0 | NULL  | sycurio1    |
|  3 | cr2       | gw3    |     3 | N        |     0 | NULL  | sycurio2    |


dr_rules;
+--------+---------+--------+---------+----------+---------+---------------------+----------+--------------+-------+-------------+
| ruleid | groupid | prefix | timerec | priority | routeid | gwlist
     | sort_alg | sort_profile | attrs | description |
+--------+---------+--------+---------+----------+---------+---------------------+----------+--------------+-------+-------------+
|      6 | 1       |        |         |        0 | NULL    | #cr1,#cr2
      | N        |         NULL |       | sbb out     |

    With this configuration , when I will place an outbound call . First
call will try on gw2 . As I have tls configuration and opensips here is a
TLS client and somehow the TLS connection won't get established with gw2
then it can't send out the request to gw2 also .
     In this case will it try to do a failover for the same call to gw3 and
try to establish connection with gw3 and send the request ?

     If this happens then in my case it's not working . Opensips sending
477 Send failed back without doing a failover here . Please suggest if
anything I need to change on my end for this behaviour to work as for our
expectations .
