Unsupported presence events

[Vladimir Ralev]

Hi guys,

I notice that  SUBSCRIBE get rejected with Bad Event response from kamailio.

This is in the log:

Dec 27 18:38:33 test kamailio[13708]: NOTICE: presence [subscribe.c:1029]: handle_subscribe(): Unsupported presence event presence

Dec 27 18:38:33 test kamailio[13708]: NOTICE: presence [subscribe.c:1029]: handle_subscribe(): Unsupported presence event presence.winfo

Dec 27 18:38:33 test kamailio[13708]: NOTICE: presence [subscribe.c:1029]: handle_subscribe(): Unsupported presence event message-summary

My initial research suggests that may be some kamailio module is not present presense_mwi or pua and some others. This can be reproduced with Zoiper upon registration on v3. Any advice?

In your local.cfg, is the presence "db_url" properly set to your
rabbit instance?

modparam("presence", "db_url",
"kazoo://guest:gu...@127.0.0.1:5672/dialoginfo")

Replace the kazoo:// URI with your rabbit's username/password and
IP/port to successfully connect.

Yes, I think I got this part right. I see plenty of hints in the log that the rabbit connection is successful, JSON exchange, AMQP notification, all of it for callmgr (registrar, which uses the same conection settings). the dialoginfo is not very chatty I guess because I don't use dialog events? Here is an example exchange:

Note that Zoiper says that it allows events about presence and kpml while kamailio says it only allows dialog events (BLF?) which sort of makes sense if the rabbit db_url is only about dialoginfo. MWI and lists are not implied. I haven't dug enough into it yet. I will trace the logs again if I missed some connection issue.

Have you tried this as UDP?

[Vladimir Ralev]

Just tried it, same error. Does non-dialog presence work for you?

[Vladimir Ralev]

It looks like it will need this in presence-role.cfg

loadmodule "presence_xml.so"

loadmodule "presence_mwi.so"

and the other presense sos in kamailio

By looking at the source only they actually add the events physically into the list of available events:

https://github.com/sipwise/kamailio/blob/master/modules/presence_xml/add_events.c

https://github.com/sipwise/kamailio/blob/master/modules/presence_mwi/add_events.c

Same suggestion as freeswitch to add the kamailio source code in the RPM so people can easily build and install missing modules in /usr/lib64/kamailio/modules/

[Vladimir Ralev]

I was trying to install the presence_xml and presence_mwi modules manually and configuring them to use the same dialoginfo rabbit URI, but it doesn't seem to reach into kazoo. Do you know if this is expected to work without extra code?
