<p class="MsoNormal">A packet capture from the phone shows the RTP stream with no audio. The operator gets calls from all locations though so the problem calls come in multiple PRIs and not just one so can't pinpoint it to a particular gateway / PRI issue.
A majority of the calls do come in the same gateway though and the PRI is clean (no errors). Let me look through the CMR records for some problem calls. I do have a TAC case on this also. Just looking for some more ideas as I've tried almost everything and
this is pretty odd. <u></u><u></u></p>

Hi,<br>
<br>
Anyone have any ideas on this?<br>
<br>
Older system, CUCM 6.1.1a (no SUs) that has been running fine for years and past 2-3 months only one user is having problems with no audio or one way audio on calls. The IP Phone user can't hear the outside caller. External calls have issue mostly. Problem
happens 1-2 times a day.<br>
<br>
We have replaced the 7962 phone, headset, put it in another switch port. Updated firmware to 8.5.2 (latest compatibile with 6.1 per docs). I have updated the IOS on the MGCP voice gateway from 12.4(15)T4 to 12.4(15)T17 and that fixed a duplicate DTMF issue
(user was hearing DTMF tones on some calls) and also seemed to help the problem calls as there are less since the IOS upgrade but still 2-3 a day compared to a dozen or so before the IOS upgrade.<br>
<br>
I haven't been able to duplicate the issue with several hundred calls in, it is very sporadic.<br>
<br>
I know the CCM version is old, thinking about applying latest SUs for 6.1 until the client can update to newer hardware. Just strange only one user having this problem. We checked around several times.<u></u><u></u></p>
