[SR-Users] [sr-dev] Regrading Kamailio

[Daniel-Constantin Mierla]

Hello,

you should watch the traffic on kamailio server to see the source ip and 
port of packets and where the SIP traffic is sent back to phones. You 
can use:

ngrep -d any -qt -W byline "sip" port 5060

I guess that the nat router assigns the same public port for all phones, 
but it forwards back only to one.

Try to set different sip port for each phone and see if it works.

Cheers,
Daniel
