We are using * as a voicemail server for a Cisco Call Manager and we
occasionally get the same thing. It can't be callerID in our scenario
since we are using Cisco PRI gateways and there wouldn't be any CallerID
tones on that. It occurs when someone calls a number and it rolls to
the voicemail server.

*Subject:* [Asterisk-Users] Asterisk answers with high pitch sound
Hi,
I've googled it and look in voip-info.org <http://voip-info.org> without
any success. Hope someone can point me to the right direction. I saw a
couple similar questions, but don't see any answers.
Fedora Core 2
2 X100P(clone) PSTN
Asterisk 1.07
Everything seems to be running fine, but on occasion, Asterisk answers
the call with high pitch screech sound (like fax or modem connect), it
plays the normal greeting after a few seconds.
I was getting this with either 1 or 2 X100P card installed. This seems
to happen when a call ends and another one comes in.
Just a side note, one thing after I installed the 2nd X100P card, the
2nd card won't answer unless I turn callprogress=no.
TIA,
John
