Hello List. I have a question about how SIP and SER work with the Registered Endpoints. Suppose that i have and endpoint with obtaining IP by DHCP. In the first attemp the REGISTER have the IP : 10.0.0.1. Suppose that after a while the enpoint is disconnected and connected again, so by DHCP it takes another IP, for example 10.0.0.5. So in my location table i see. ----- aor : '5555832351' Contact : 'sip:5555832351@10.0.0.1' Expires : 642 ----- aor : '5555832351' Contact : 'sip:5555832351@10.0.0.5' Expires : 3000 ----
So when i call to the 555-5832351 SER generates two INVITES (to the 2 registered endpoints) but only the 10.0.0.5 answer the call. So far this is not a problem, but suppose now that a new endpoint with number 5555832359 obtain by DHCP the old IP 10.0.0.1, so it tries to register with the SIP-Proxy . What i see in the location table is now:
----- aor : '5555832359' Contact : 'sip:5555832359@10.0.0.1' Expires : 3000 ----- aor : '5555832351' Contact : 'sip:5555832351@10.0.0.1' Expires : 442 ----- aor : '5555832351' Contact : 'sip:5555832351@10.0.0.5' Expires : 2800 ----
So when i call to the 555-5832351 the INVITE goes to these 3 endpoints. Generating too much traffic and erroneus RESPONSE messages in SER and in the endpoints. My question is : Is posible only permit one IP address per endpoint registered in the location table?. Or make sure that only one endpoint with a given IP and URI is registered in the location DB?.
Thanks in advance Best Regards
