[asterisk-users] MWI, Realtime SIP, Voicemail and Extensions, UAs registered with SER

[kjcsb]

>I have the following setup:
> - UAs registered with SER/OpenSER
> - SIP peers (non cached), extensions, voicemail setup (not message 
> storage) defined in Asterisk 1.2 using Realtime
>
> When a message is left in the user's mailbox, no Notify message is sent to 
> SER.
>
> 1. If the SIP peer is defined in sip.conf with a host=ser.domain.com then 
> the notfy is sent to SER.
> 2. If realtimecache=yes is set in sip.conf and the SIP peer is visible 
> with sip show peers and the SIP peer host field is set to ser.domain.com 
> then the notify is sent to SER.

> - Method 2 of http://www.voip-info.org/wiki-Asterisk+at+large relates to 
> SIP UAs registered with SER and states that Asterisk sends NOTIFY only to 
> UACs that are registered at the Asterisk. This is not the case as 
> described in 1 above and Method 5 of Asterisk-at-large.
> - Method 4 of http://www.voip-info.org/wiki-Asterisk+at+large assumes 
> cached SIP realtime peers. I don't want to cache.
> - the posting http://forums.digium.com/viewtopic.php?t=4363&highlight

> SER.
> - the article 
> http://openser.org/dokuwiki/doku.php/asterisk:realtime-integration doesn't 
> deal with MWI.
> - the posting http://asterisk.mdaniel.net/?p=14 creates the msg<num>.txt
