asterisk users - May 2007 - Call waiting tone when calling a busy station?

Hello,

  When dialling a SIP phone which is already in a call the caller hears a
"regular" ringing tone and does not know that the called party is
engaged in
another call. Is there a supported way inside SIP to tell the calling party to
play a stuttered ringing tone?

                                       Thanks! __Yehavi:

Hello,
    this is a SIP phone configuration issue.

You should tell the UAC to not accept a second call while the line is 
engaged (look for a 'Call Waiting' option in the configuration of the
UAC)
The UAC will send back a 486 "Busy Here" error code and the calling 
party will get a busy signal  from asterisk

The calling party will then play a busy tone, or Asterisk will emulate 
it in case of analog zaptel devices

This is not what I meant. I want the called party to get a sign of a waiting
call and answer it if he/she wants. I want the caller to know that he on a
waiting call (here it is customary to play a stuttered "ring" tone).

in short - can I signal in the "183 ringing" packet that this is a
second call?
