Thank you Tim, It was really helpful, but it is not impossible I think. I solved the problem for changing network in a call. What's I am doing is just send RE-INVAITE from the client. Yes, there is a small gap (< 1sec.), but it is acceptable. When this gap is used to inform subscriber for changing network the things are going pretty well. Of course, the client sends REGISTER as far as possible. So, from my experience: sending RE-INVITE with SDP is enough to force freeswitch to send media to correct destination. Changing the registration in a call will not force freeswitch to send BYE to correct destination after bridge ends (maybe it is a bug, maybe not, I am not sure). The problem that I should to solve is when client changes his network between RING and ANSWER. So, freeswitch will receive new registration, but how to close existing bridge in case when client change his network? In this case RE-INVITE does not work. The idea I have, but not tested is to send BYE from the client, with the same Call-ID and some special reason. After that maybe I will be able to bridge call again with correct parameters.

The only way is if the phone registers. FS won't even know where to send the next packet until the phone does another registration so it gets an update. If you have a registration for both the WiFi and 3G address, you will have better luck, but I think FS will still maintain the contact info for a dialog that has already started. If this is a problem you really need to solve, then you may need to set up some sort of VPN so that a common IP address can be reachable over both 3G and WiFi. Even then, there is still going to be a period of instability when you transition, as the routing has to re-converge. You also can't transition an active call between WiFi and 3G for the same reasons. The only way to do that would be to park the call, re-register on the new network, then pick it up again. Hope that's helpful. -Tim Mario Karakanovski wrote:
Thank you Mitch,
The client use TCP, but the problem is that it must change IP address, because it's switch between WiFi and 3G. So, there is no chance to force it using the same IP address.

Try changing the mobile client to register via TCP I would assume then the IP will not change as that would break the TCP connection:)

Hi guys,
I have an interesting situation.
I have two mobile clients and connect them using bridge. It is working without problems, except when the called party changes its IP address between ringing and answer.
Does anybody deal with such situation?
