Let me answer my own question. That may save someone's frustration in the
future.
The problem is that the Realtime peer never gets loaded, since SIP REGISTER and
SIP SUBSCRIBE never reaches Asterisk.
Doing a simple sip show peer az5134939706 load from CLI will force load of
peer. However, I needed a way of having this done automatically on startup for
all (many!) peers. A number of methods are suggested by people (use Google) but
they all seemed like hacks to me.
Finally I realized, after rereading chan_sip.c, the solution was to force load
the peer from dialplan. If I do this just before I send a caller to voicemail,
I can be sure the peer is available when MWI NOTIFY should be sent. Just add
this to the dialplan:
same = n,NoOp(${SIPPEER(az5134939706)})
Good luck with your Realtime MWI hacking!
Best regards,
Jan

Subject: [asterisk-users] MWI for non-subscribed Realtime peers?
Hi,
I have an Asterisk behind an OpenSIPS proxy. The proxy handles registrations
and also SIP SUBSCRIBE for MWI. The Asterisk are configured to send NOTIFY to
the proxy even when the SUBSCRIBE haven't been received. I can configure a user
in sip.conf that works:
[az5134939706]
type=friend
host=xxx.xxx.xxx.xxx (IP of proxy)
port=5060
nat=no
mailbox=1234@customer
subscribemwi=no
defaultuser=az5134939706
Every time a voicemail has been left in the mailbox 1234@customer, a NOTIFY is
sent off to the proxy. Remember, the peer doesn't register or send SUBSCRIBE to
Asterisk, but subscribemwi=no forces NOTIFY to be sent anyway.
However, I am struggling to get the same thing working for Realtime peers. I
have rtcachefriends=yes set in sip.conf. But I never see the peer loaded from
database and no NOTIFY is ever sent.
Is it possible to user Realtime this way? What will trigger loading of the peer?
Best regards,
Jan Blom
