We have CallManager 4.1 in location A. Its branch office (location B) have IP phones connecting to the CallManager via Fiber. Location B was setup long back and things are working fine without any issues. Now location C is a sub-branch of B. B and C are linked via VPN (Junniper's 5GT NetScreen both ends). IP Phones in C register with the CallManager in A via the VPN and via the Fiber WAN link. Everything for C works fine except sometimes when they try to call an extension in B, they get a fast-busy tone. Most of the phones work most of the time.
