The SIP reply is routed based on the address in the VIA header. The
address in VIA is set by each node sending a request, if between the
request and the response the sender is no longer available at the
address it added as VIA, then it is little one can do for that.
You can try not sending the 100 trying, so the sender does
retransmissions. Also, maybe the sender should send a new re-invite as
it changes to a new network again.

Greetings all.
I have following use case:
0) Peer A and B registers on kamailio via TLS.
1) Peer A establishes call to peer B.
2) Peer A changes network and call has to be refreshed. Peer A
reregisters, gathers ICE candidates, builds reINVITE and sends it to
B. After peer A changes network again, reregisters and waits for
answer from old reINVITE.
3) Peer B receives reINVITE and sends answer.
The problem is this answer never gets to peer B. Kamailio cannot
route answer as old TLS connection is closed and new one did not
established before reregistering.
Is there way to solve or avoid this situation?
Thank you :)
