[Asterisk-Users] Asterisk answers with high pitch sound

[info at beprojects.com]

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.
