[asterisk-users] Call waiting tone when calling a busy station?

[Yehavi Bourvine +972-8-9489444]

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:
