You could use 300 Multiple Choices to implement Voice mail service. The call flow could be like this:
A proxy redirect B Voice mail server | | | | | |---INV B------>|---INV B--->| | | | |<---300---- | | | | |--- ACK --->| | | | | |---INV B--->| | | |<----------------180-----| | |<---180--------| | | | |----CANCEL-------------->| | | |<------200 ------------->| | | | | | | |----INVITE: Voice mail server-------->| | |<-----200 OK--------------------------| | |----------ACK------------------------>| |=====================RTP==============================| | | Thanks, Sai. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sarju Garg Sent: Wednesday, June 07, 2006 9:16 AM To: Sarju Garg; SIP-implementors mailing list Subject: [Sip-implementors] Query Regarding Voice Mail service using SIP Hi all, I have a query. I wish to implement voice mail service using SIP. I am aware of CC-Diversion parameter but it is not still part of standard SIP. Is there any message/parameter to implement this service. Thanks in advance Regards Sarju _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
