[cisco-voip] One-way Voice Issues

[Weigand, John V.]

Serious Medicine for the Defense R 

Our CCM5.x system was installed by our vendor back in February. Since
then, we've had an ongoing one way voice issue. Every so often (mostly
reported by our phone receptionists, but by a few other key users),
they'll either receive or make a call, and be nearly unable to hear the
person on the other end. They can just barely make out their voice, and
adjusting the phone volume does nothing. The person on the other end is
able to hear them with no issue.

 

We've tried swapping the phones, etc, with no luck. I've had no formal
Callmanager or even VOIP training, but I've been able to pick up a lot,
and administration of the system has fallen to me. I found this document
<http://www.cisco.com/en/US/tech/tk652/tk698/technologies_tech_note09186
a008009484b.shtml>  about troubleshooting voice issues, and (based on my
very limited knowledge), I'm wondering if it has something to do with
Media Termination Points. Based on what I've read, there's a difference
between configuring those on CCM4 and CCM5, and our vendor really knew
nothing about CCM5, and set it up as if it was CCM4.

 

Can anyone give me some guidance on how I can learn more about
this/figure it out/any other possible ideas what could be causing it?

 

Thanks so much!
