Hello,
Looking for pointers as to what I'm missing here.
I'm using the presence module to allow UAs to subscribe to
message-summary events. I can see the entries appearing in the
active_watchers table and I see subscription renewals increment the cseq
columns so I'm satisfied this part is working well.
I'm having trouble finding out how to tell Kamailio about a change to
the message-summary so that it can notify the watchers.
The pua module seems to provide a way but it doesn't seem to work with
the subscriptions set up by the presence module. The presence module
itself does not seem to offer any RPCs capable of doing this.
Appreciate any pointers!
Thanks,

Hi Trevor,
Typically, your voicemail server would send a publish to Kamailio, which
would then notify each of the watchers.
A call to handle_publish() should be all that’s required.

umm that sounds interesting: i have in my cfg file presence
configured, and also configure asterisk realtime, and my led in
phones does not get on and only works if i setup the phones only with
asterisk!
here my configuration:
route[PRESENCE] {
if(!is_method("PUBLISH|SUBSCRIBE")) {
xlog("[$Tf] presence rule: not forwarding sub/pub requests??????\n");
return;
}
if(is_method("SUBSCRIBE") &&
$hdr(Event)=="message-summary") {
route(TOVOICEMAIL);
# returns here if no voicemail server is configured
sl_send_reply("404", "No voicemail service");
xlog("[$Tf] presence rule: not forwarding voicemail requests??????\n");
exit;
}
#!ifdef WITH_PRESENCE
if (!t_newtran()) {
sl_reply_error();
xlog("[$Tf] presence rule: error??????\n");
exit;
}
if(is_method("PUBLISH")) {
handle_publish();
t_release();
} else if(is_method("SUBSCRIBE")) {
handle_subscribe();
t_release();
}
exit;
#!endif
# if presence enabled, this part will not be executed
if (is_method("PUBLISH") || $rU==$null) {
sl_send_reply("404", "Not here");
xlog("[$Tf] presence rule: nothere publish requests??????\n");
exit;
}
return;
}

Thanks Charles, unfortunately I am not using a voicemail server that
would understand how to do that, so I'd have to generate it myself.
An RPC would be the easiest way but if that is not possible I can
generate the PUBLISH myself. I'd just prefer to avoid dealing with SIP
directly for this purpose if possible.
Thanks,

Hi Anthony,
Thanks so much! The example you provided led me in the right
direction. I've made use of XML_RPC (rather than JSON) using this same
approach and have successfully managed to set my softphone to show that
there are new messages.
Best regards,
