[Asterisk-Users] Terrible inbound call quality vs. outbound

[Robert Goodyear]

Hi. I'm having a terrible time with call quality coming into my * box.

I'm using VoicePulse over a 1.5/1.5 mbit line. Outbound calls are 
crystal clear on both the RX/TX sides of the conversation. Inbound 
calls, though, are HORRIBLY garbled on the RX side. I can barely hear 
the caller, but they report my quality is fine. Getting loads of 
garbled sounds and weird echoes. (Could just be jumbled up voice 
packets?)

Details:
2.4 GHz P4
Fresh Fedora Core 3 install
Fresh Asterisk install

VoicePulse connect service
Cisco 7960 phones
Gigabit routing and NICs internally

Any ideas?
