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

[Matt Klein]

Try voicepulse in a different area w/ 800 service. With 800 you can jump 
POPs. If you're stuck with local DID service w/ them, I feel sorry for 
you.

I've seen several recent complaints, and have experienced my own problems, 
with voicepulse inbound service. They need to upgrade the POP (wherever 
you are) to add more bandwidth and/or more lines (depending on if you're 
getting choppy sound, or if you're getting fast busies, etc).

Personally, I'm cancelling service in a week or two.

Call them and complain, if you think it'll do any good.
