<br><font size=2 face="sans-serif">In the archives someone mentioned bad
DSP's on the phone. How many phones did you return and what type
were they 60,61 etc? Your whole batch was bad? Were your phones in
production for a while before it happened or did it occur right away? I
am trying to see how close I am to your scenario.</font>

<br><font size=2 color=#1f497d face="sans-serif">Client of ours came across
this issue for a batch of phones last year. Performed a factory reset,
moved the phones off to a different switch port, moved them to a completely
different switch, upgraded the firmware, swapped out the patch cables,
checked call statistics for lost packets….. As for codec mismatches or
unregistration events, CCM traces didn’t show any codec mismatches (no
transcoders invoked) or gateway unregistration events or d-channel
flaps during the time the problem occurred. SCCP and Q931 signaling showed
the disconnect was issued from the end user, not PSTN. Eventually opened
a TAC case and was told it was due to hardware failure. Client RMA’ed
the IP phones and never encountered the issue again.</font>

Started seeing this error message last week at a remote location connected
via MPLS on several phones intermittently. People are actually
on a phone call and get disconnected when the message appears. After
searching the archives it looks like there are multiple possibilites for
the cause of this message: Packet loss, DSP issues, Codec mismatch, MGCP
gateways unregistering, etc.</font><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="Arial"><br>
Anyone have a clue what the likely cause would be when you have an H.323
gateway and calls are already connected but get dropped in the middle?</font><font size=3 face="Times New Roman">
