I'm not sure, but it appears to me that check in line 95 from https://github.com/kamailio/kamailio/blob/5.2/src/modules/presence_mwi/add_events.c is not passing. I was trying to add "\n" and "\r" to the end of each string but I always had failure on character number 22.

Does anyone know how exactly PUBLISH packet body should look like?

Thanks a lot!
