Hi David,
With TCP, there is no need to have the TCP connection up during the
whole duration of the registration - it is perfectly normal for the TCP
conn to be terminated after REGISTER request (by server or client side).
For example, opensips has a timeout - for how long it should keep an
unused TCP connection (see
http://www.opensips.org/Resources/DocsCoreFcn16#toc73).
If the UAC is behind NAT, it is a bit of different story, as the TCP
conn must stay open - the server cannot open later a TCP conn behind
NAT. For such cases see:
http://www.opensips.org/html/docs/modules/1.6.x/registrar.html#id250051
Regards,
Bogdan

I am noticing a strange behavior on the phones.
They are connecting over TCP; It seems like every 3 minutes they
quickly lose registration and then re-register.
I am not sure if it is because the phone is sending a register every 3
minutes and then opensips is closing the old socket and opening a new
one or what?
I dont have that much experience using TCP or how do troubleshoot this
problem.
Thanks.
