[SR-Users] Help Asterisk with Kamailio unable to register with remote VOIP providers

Mon Jan 2 17:31:01 CET 2017

HI Daniel,

Here is another problem. Kamailio responds with SIP/2.0 478 Unresolvable destination (478/SL) to REGISTER requests sent by asterisk for VOIP provider. Domain "ims.airtel.in" does not exist. Where can we map this in kamailio.cfg?

Retransmitting #3 (NAT) to 103.35.68.236:5060:
REGISTER sip:ims.airtel.in SIP/2.0

Hi,
please configure this in your kamailio.cfg:

debug=3  # debug level, 1 is low and 4 is high (lots of output)
log_facility=LOG_LOCAL7

...
loadmodule "/usr/local/lib/kamailio/modules/xlog.so"
...

As well as this in your rsyslog.cfg:

# Kamailio (OpenSER) messages, make sure this spacing is done with tabs, 
spaces may cause errors
local7.*                                            -/var/log/kamailio

Please notice that you have to restart kamailio and rsyslog.

Also remember to set the log facility in your xlog lines, e.g:

xlog("L_NOTICE", "This is a standard log line\n");

After restarting the processes, what do you see in /var/log/kamailio ?
What do you get from kamctl fifo debug ?
