Module: kamailio Branch: 5.1 Commit: 942445c2c3844ae5d2692d7c734cb1375caed849 URL: https://github.com/kamailio/kamailio/commit/942445c2c3844ae5d2692d7c734cb13… Author: valentin &lt;christoph.valentin(a)kapsch.net&gt; Committer: Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; Date: 2018-06-04T15:06:15+02:00 ims_isc: initial fix of issue #1168 Function isc_match_filter() got a new local variable firstflag in order to handle the case where a FAILURE_ROUTE callback is received before the first AS has been contacted. The firstflag is also forwarded to function isc_forward() as parameter. --- Modified: src/modules/ims_isc/ims_isc_mod.c Modified: src/modules/ims_isc/isc.c Modified: src/modules/ims_isc/isc.h --- Diff: https://github.com/kamailio/kamailio/commit/942445c2c3844ae5d2692d7c734cb13… Patch: https://github.com/kamailio/kamailio/commit/942445c2c3844ae5d2692d7c734cb13… --- diff --git a/src/modules/ims_isc/ims_isc_mod.c b/src/modules/ims_isc/ims_isc_mod.c index e0f7b940ee..4618ca7db1 100644 --- a/src/modules/ims_isc/ims_isc_mod.c +++ b/src/modules/ims_isc/ims_isc_mod.c @@ -224,6 +224,8 @@ int isc_match_filter(struct sip_msg *msg, char *str1, udomain_t* d) { //sometimes s is populated by an ims_getter method cscf_get_terminating_user that alloc memory that must be free-ed at the end int free_s = 0; + //the callback from the Cx interface in case of unreg terminating initial message is a FAILURE_ROUTE.
