Not sure if I understood correctly your problem, but that sounds a lot like forking the call as soon as another REGISTER comes in for the same AoR.

In that case, it may be worth to have a look into TSILO module, it may help you in your case.

Hello group,

The call flow is:

useragent (TLS) -> Kamailio -> Sems Server.

During the establishment of a call (before the 200OK or during a retransmission of the 200OK issued by Sems Server via Kamailio),
if a user agent (TCP) loses its connection (the user agent is on a mobile network for example or the network is not reliable.) and sends a "register" to Kamailio (same source IP address but a different source TCP port), is it possible for Kamailio to take into account this new TCP port with the function t_relay () ?
