Calls forwarding after one ring intermittently

Unanswered Question
Aug 23rd, 2009

Customer has CCM 7.1(2) installed. CEO's phone is set to forward after 12 seconds in the event of RNA.

Customer reports that there is an intermitent problem where the phone will ring once, and then forward before he can answer.

Trying to determine possible causes of this problem. Nothing found in the bug toolkit.

I have this problem too.

Although Cisco CallManager is unable to control the actual number of rings explicitly, a user can adjust the Forward NoAnswer Timer value in the service parameters. This is the value used for waiting; to allow x amount of rings. The default is usually 12 seconds, which allows two to three rings before diverting to voice mail. This value can be increased for the number of rings required (assuming 4 seconds for each ring). For example, if it rings five times, set this value to 20 seconds.
