Request to all – Please help we are BADLY stuck in this asterisk 11.13 and Kamailio 4.1 integration provided with Elastix MT

 

Our Configuration is like this:

 

Asterisk IP – 10x.3x.6x.236 port 5080

Kamailio IP - 10x.3x.6x.236 port 5060

 

Please see our kamailio.cfg attached.

 

Issue 1:

Issue is REGISTER messages sent by asterisk are not responded by kamailio asterisk is constantly doing a re-transmit on REGISTER messages.

 

Retransmitting #1 (NAT) to 10x.3x.6x.236:5060:

REGISTER sip:ims.airtel.in SIP/2.0

Issue 2:

We are not able to see any log messages in /var/log/kamailio.log. We have done all kind of changes suggested on online blogs

 

Why does kamailio not have a pre-set configuration as it is mostly used as sip proxy?
