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

[Gene Willingham]

Unfortunately no matter how much Qos tagging you do it will not help the
inbound side of your call.  Qos is a two way street.  Everyone in the path
has to support it.  If even one router in the path does not support it you
can get very poor results.  

Wouldn't it be funny if Voicepulse was not doing Qos tagging with QOs on
their routers?  The drops in the incoming calls could be they are not
prioritizing voice traffic.  The outbound leg is fine because you are.

Also, as mentioned before, the quality issues I am experiencing only occur
on some DIDs.  Specifically 703 numbers are the worst.  Last week during the
4 hour outage, 703 (reston Virginia) numbers would not work but 240
(Bethesda Md, across the river) did.  Go figure.

Try www.txlink.net.  They may have a DID in your area.  They have a fairly
large calling area.  They have a different pricing model then Voicepulse,
but that may work in your favor.

Yeah, I've been beating my head against the wall thinking it was 
something with my config, but alas, it seems to be a case of me needing 
to RTFF (Read The Effing Forum) and ask the community about their 
experiences.

Sadly, VP seems to have a fairly high comparative "rating" against 
other VOIP service while they seem to maintain horrible customer 
support and crappy line quality. Sigh.

I wonder why the TX side of the conversation is clear though? Seems 
like the packets would be treated identically since it's a full-duplex 
conversation.
