Can Kamailio be used to redirect media between a client that switches from wifi to 3g/gsm

The use case is that I have a SIP client registered to Kamailio talking to
an Asterisk box connected to the PSTN. The client is a mobile phone and the
user is connected to wifi. The user then steps out of wifi range and the
phone drops the connection and picks up the 3g data connection. I want the
media stream to reconnect to the client and the call to resume without
having to redial. This works now if the client is directly connected to the
Asterisk machine, but not when I am routing through my Kamailio server. How
do I go about this, examples are always appreciated, thanks!

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
