Re: [Kamailio-Users] BLF and MWI problem on Grandstreams

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… regards klaus 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. David schrieb: > All, > > I upgraded to Kamailio 1.5 and had a lot of problems getting BLF and > MWI working.
