Hello,

from the log, the alias should be in r-uri unless there is a strict record router somewhere. You should post here the sip trace from invite to ack to look at the signaling.

Cheers, Daniel

I trying to debug why Kamailio is dropping certain ACKs. I have debug level set to 4 and cfgtrace on. The last thing I see in the log for my missing ACKs is:

Aug 26 12:22:29 eng-reg1 kamailio: ERROR: *** cfgtrace: c=[/etc/kamailio/kamailio.cfg] l=789 a=16 n=if Aug 26 12:22:29 eng-reg1 kamailio: ERROR: *** cfgtrace: c=[/etc/kamailio/kamailio.cfg] l=786 a=25 n=check_route_param Aug 26 12:22:29 eng-reg1 kamailio: DEBUG: rr [loose.c:974]: check_route_param(): params are <;alias=172.16.3.65~5060~1> Aug 26 12:22:29 eng-reg1 kamailio: ERROR: *** cfgtrace: c=[/etc/kamailio/kamailio.cfg] l=795 a=16 n=if

Which corresponds to these lines in the config:

    if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) {

return; }

    if (is_request()) {            <---------LINE 795

if (!has_totag()) { if(t_is_branch_route()) { add_rr_param(";nat=yes"); } } }

Why would that be the last line that is traced? Is Kamailio really not processing past here?
