I apologize in advance if this message duplicates a previous post or the topic has been covered elsewhere. If that's the case, a pointer would be appreciated!

I have multiple offices each running Freeswitch and a number of Polycom phones and softphones.

I would like to share the presence information between the offices, such that if a person in Office B can see if a person in Office A is on the phone. I personally don't know of any way to do this through Freeswitch as it stands. I have thought about using a VPN for the offices and just setting up the phones to all register to a single server, however I don't want calls between phones in the same office (intra-office) to have to be routed all the way through a different office, which may be on the other side of the world and costs bandwidth.

Any suggestions as to the best way to accomplish this would be greatly appreciated. Thanks!

Hi Kenneth,

I'm not going to answer your question! Instead I would like to emphasize on the thing you are going to achieve because some times ago I've post this question in some other title but unfortunately did not get any answer. As the SIP protocol's point of view you should be able to subscribe every FreeSWITCH machines for external events in another one (or probably in a central PRESENCE server such as SER) to get NOTIFY messages which indicate the information you wish to have. Although the sofia SIP endpoint can do this (as you can find in its features) I could not find any guidelines for it in FreeSWITCH.

Regards,

Check out mod_event_multicast. I think you should be able to share using that to share events between boxes (although I have never tried it).
