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

[Robert Goodyear]

To Bryan, Brian, Daryl, David and others who have reported the same 
VoicePulse inbound problem I am experiencing:

In my extreme efforts to debug this inbound call quality situation, it 
seems that if I disable the IAX2 registry and instead register a SIP 
channel against VoicePulse (gw5.voicepulse.com) for my inbound context, 
the call quality issue is completely fixed.

Do any of you guys have a moment to try that out on your configuration? 
It may help us all in our attempts to pinpoint this issue... even if VP 
is not willing to put any efforts into diagnosing this.

Thanks,
/rg
