[SR-Users] Can Kamailio be used to redirect media between a client that switches from wifi to 3g/gsm

[Klaus Darilion]

Hi Shaun!

Your problem description is too short to give you any good help.

Use tcpdump (or other tools) to capture the scenario with Asterisk and 
Kamailio. Then compare them to find out why it doesn't work.

Is media sent directly to Asterisk then it ca not be the problem of 
Kamailio.

I hope the mobile client is smart enough to also send a reINVITE when 
getting the new IP address (of the mobile connection) with proper 
Contact header - otherwise it can not receive SIP requests from Asterisk.

regards
Klaus
