Running UCM 6.1.2.

When user dails the international number,call will be routed through Service Provider Router where the IPLC link is terminated.

In UCM created SIP trunk with an IP Address of Service Provider's Router.

Currently we are facing problem like,calls are getting dropped after 15mins.

Pls help me out to resolve it.
