Hello dears,

I'm using kamailio devel version as an IMS (P-CSCF,S-CSCC,I-CSCF) with forking mode  ,when more than one client registered with the same AOR and the servers received a call to that Aor All the clients ringing , after that one of the clients answer the call which will cause cancel message with reason call completed elsewhere .

This cancel message affect on the running call which answered by one of the client and terminate it .

So how to set up kamailio to allow registration only for one client per Aor or to prevent the affection of this cancel messages .

Thanks in advance & best regards
