96XX SIP phones

[janaya]

Avaya CM7 using 9601 SIP phones.

Calls to the phone have a distinct buzzing/static on the line. This is all phones. We also use Equinox softphones and have no issues with those.

Anyone seen anything like this before? Fixed this issue?

Is this on all calls, internal to internal or just from a internal sip to an external outside line?
Does list trace station xxxxxx show any odd or high jitter or other packet loss issues?
Are teh codecs set correctly for that network region in which the sip phones are using?

Just a couple of quick things I Could think of.

It's all calls.
Internal SIP
Outbound PSTN over PRI
Inbound PSTN over PRI

No jitter on the trace and not able to hear listening to the RTP packets from Wireshark.

Just hear the buzzing and static on the handset.

One thing to note. I had someone checking a set and they happen to have a toner and a probe and when he put his probe against the phone there was a buzz much like you would hear if you put your probe against a power cord. Network team checked the POE output and it was at 4W.

RESOLVED - Bad Firmware on the phones. Flashed with latest firmware and issues were resolved.
