Hi everyone, I have a cluster of 4 CallManagers Server version 7.1 in Site 1, 1 Publisher and Subscriber 1 and Subscriber 2. I installed a Subscriber 3 in Site 2 over a WAN link with Round Trip Time of 71 ms and 8Mbps of bandwidth. My issue is that, when I have a IP PHONE registrated in Subscriber 1 of Site 1 and try to call a IP PHONE registrated in the Subscriber 3 of Site 2 the call can no be established and i hear a busy tone in both directions but when i try to call from a IP PHONE registrated in Subscriber 2 to an IP PHONE registrated in Subscriber 3 the call is established.
The calling seach space of IP PHONES and the routing call are ok and synchronization of Database of all Servers are good (2).
anyone can help me?
If the call rings at the Subscriber-3 IP Phone, it means there's no problem with the signaling. For me this sounds like a codec issue. Are you using G.729 over the WAN?
