I have a problem in a Branch office where some calls do not get through or get dropped.
Configurations is as follows:
1)2 Pri and with Overflow with N1 signalling. PRI are clean
2) Connected to a 3825. Which connected to Layer 3 switch 3750
3) Vlans for VOIP, Server network, Wifi, Users
4)CCM and Unity in Head office connected via VPN tunnel over frame relay (to T1 full 1536)
5) We use SCCP and phone are 7070,7960,7936
6) The MGCP 3825 was upgraded to the latest version 12.4(16) to solve the problem.
Question is how best to tackle the problem?
Also to fix local voice quality I just changed the codec tonight g7.11 from g7.29.
Thanks in advance or all help!
