[Asterisk-Users] MWI's for Third Party Softswitch

[Jay Ray]

Hi All,
 
   I want to use Asterisk for VoiceMail for a softswitch. 
 
I can dial in to leave voicemail and retrieve. Now there are many SIP Endpoints registered to the Softswitch. The Asterisk is sending a NOTIFY msg to the Softswitch on <ip addr>:0
 
 
Somehow Asterisk Looses the port from where the INVITE came in, this NOTIFY msg is not going out of the Asterisk, I cannot see in Ethereal. here is the Error I get constantly on the CLI prompt...
 
Mar 28 13:27:38 WARNING[2044]: chan_sip.c:682 __sip_xmit: sip_xmit of 0x9204bd4 (len 457) to 12.42.87.60 returned -1: Invalid argument

Can someone direct me to the portion of the Code where Asterisk Generates reponses for Voice Mail Call Flow. I would think goes through the Normal SIP stack.
 
Another thing I want to do it send the MailBox Number back in the "To" header of the NOTIFY that is being sent to the Softswitch. The Softswitch will then direct the Notify to the Appropriate Endpoint.
 
 
Any help or guidance appreciated.
Jay
