What I meant was :
MWI ( presence message-summary ) not MWI ( Dialog message-summary ).

Hey,
Also, to get MWI ( Dialog message-summary ) to work with my linksys, I
have this parameter :
modparam("presence", "max_expires", 2147483647 )
The Linksys never resubcribe to MWI. So watch out for that one.

You are right - if the presence server is included in the "normal"
proxy, then the SUBSCRIBE-dialogs do not have a route-set and thus
can not be routed with loose_route. Adding the exception for PUBLISH
too should not be necessary as PUBLISH never have to-tag.
It was fixed int he default config for 1.5. Take a look at
http://openser.svn.sourceforge.net/viewvc/openser/branches/1.5/etc/kamailio.cfg?revision=5926&view=markup

PS: Some older SNOM phones had a bug and sent in-dialog SUBSCRIBE
without using the Contact provided by the presence server, but
instead always using the initial SUBSCRIBE URI. Depending on your
config this can cause problems too.

All,
I upgraded to Kamailio 1.5 and had a lot of problems getting BLF and
MWI working. So I will list here some of my notes in case some body
else ever has the same issue.
Firstly, in my tests I am using a GXP2000, GXP2020 and a SPA962. I
also tested with a SNOM360.
my issue was the MWI seemed to fail after an hour, and I could not
find why. So in searching my config, I found that when the phones
were resubscribing to MWI and BLF, it was being caught in this
condition :
if (has_totag()) {
if (loose_route()) {
if (is_method("BYE")) {
setflag(1); # do accouting ...
setflag(3); # ... even if the transaction fails
}
route(4);
}
else {
sl_send_reply("404","Not here");
exit;
}
}
My subscribe code handling was after this block, I noticed the issue
from the 404 the grandstream was getting when trying to subscribe. I
therefore added handling for the subscribe packets in this section,
and my MWI and BLF seems to be working.
else if ( is_method("PUBLISH") || is_method("SUBSCRIBE") )
{
route(5);
exit ;
}
Where route(5) does the appropriate handling of these two types of
SIP packets.
It should be noted, when I speak of MWI I am referring to presence
message-summary which is sent via a publish by my media application.
When I write BLF, I am referring to Presence Dialog.
So when my phones were resubscribing, they are being sent a 404.
I tested the Grandstream and the Linksys, and both seem to have the
problem resolved. I will test this with the Snom tomorrow and post
my results.
David
