points to note.</span><o:p></o:p></p>
<p class=MsoNormal style='background:white'><span style='font-family:"Arial","sans-serif"'>You're
really not experiencing a 1 way audio issue. 1 way audio is typically when the
return audio stream is lost in one direction entirely via a routing issue
or similar and you have no audio (dead air) in one direction. You are however
running in a voice quality issue that can be a pain in the ass to track down.
I've run into very similar issues a few times in the past and it has always
turned out to be one of 3 issues. I'll assume that these are all external calls
to or from the PSTN that are being affected, I can't invision this occurring on
an internal call unless this audio stream was hitting a WAN or VPN link in
which case it could be a QOS issue (or lack of QOS). </span><o:p></o:p></p>
<p class=MsoNormal style='background:white'><span style='font-family:"Arial","sans-serif"'> </span><o:p></o:p></p>
<p class=MsoNormal style='background:white'><span style='font-family:"Arial","sans-serif"'>1:
Bad DSPs on the Voice gateway which explains the intermittent problem if its
only one or a part of a DSP that's bad and is only hit intermittently </span><o:p></o:p></p>
<p class=MsoNormal style='background:white'><span style='font-family:"Arial","sans-serif"'>2:
Buggy code on the IOS gateway, there were some really ugly DSP type bugs in
previous code that could be causing this. </span><o:p></o:p></p>
<p class=MsoNormal style='background:white'><span style='font-family:"Arial","sans-serif"'>3:
PRI issue/provider issue, low signal or similar on the PRI</span><o:p></o:p></p>

<p class=MsoNormal style='background:white'><span style='font-family:"Arial","sans-serif"'>Out
of the 3 I'd be leaning towards bad DSPs but any of the 3 will likely require a
TAC case.</span><o:p></o:p></p>

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. <o:p></o:p></span></p>

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 <a

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. <o:p></o:p></span></p>
