Hi

I meet some problems on CIPT.

1.IP Phone call to PSTN, hear a lot of noice, it's so sound than can't bear, but the external side, it's acceptable.

2. IP Phone call to PSTN, user have to press "#" or wait a lot of time to complete a dial, how to change this timeout timer? Dial pattern is 9! and 9!#.

Network structure:

Callmanager-Unity-Cisco2651XM(IOS 12.2(15)T9) as a H323 Gateway-> E1 Pri.

Appreciate any help!
