<DIV>Hi All,</DIV>
<DIV> </DIV>
<DIV> I had proposed the changes to be able to support Asterisk VoiceMail for 3rd Party Softswitches. Here is what I have changed on Asterisk in chan_sip.c</DIV>
<DIV> </DIV>
<DIV>While in function sip_send_mwi_to_peer() . in case peer->tohost has a value which means that its not a registered EP - but a static peer, I call another function called sip_send_mwi_to_softswitch() .....in which I separate the comma separated mailboxes defined in sip.conf for that peer. and send NOTIFY in a for loop for each of the Mailboxes....by calling another new function transmit_notify_to_softswitch_with_mwi()</DIV>
<DIV> </DIV>
<DIV>In transmit_notify_to_softswitch_with_mwi() , I populate the sip_pvt->username with the mailbox number (minus the mailbox context, if any)...so that the mailbox number gets added to the "TO" header in the NOTIFY going out to that Softswitch...for the Softswitch to pass on the NOTIFY to the appropriate Endpoint....</DIV>
<DIV> </DIV>
<DIV>The DIFF is below, comments appreciated.......</DIV>
