[Serusers] call signalling between voice mail and answer_machine

Dear All, I want to know the call signaling between sip user agent and answering_machine. Suppose I made a call for user "matsu" and if she wants to recive only voicemail then then this call will be forawarded to answer_machine by SER proxy. Now what will the call signaling going on before to start the rtp session..either this new call signaling will handle by answer_machine or SER. as when i made a call to the user then who wants only voice mail, I get first the message as "100 try and ringing" on my user agent and after that i get 408 request time out... I need to know that if every thing will fine then what is the call sequence... thanks & regards koyama --------------------------------- Do you Yahoo!? Yahoo! Mail Address AutoComplete - You start.
