Back in version 7 (I think) the 3CX assistant arrived along with presence over bridges. It was great, worked really well. Then MyPhone arrived and presence over bridges, at least for us, was broken. With each version I try to see if it will work again, and so I hoped V15 (which is a great step forward - good job guys!) it might be resolved, but unfortunately not. Setup as follows: 3 Sites with their own PBX's. Each site connected to the other via a VPN (router based). Bridges go over the VPN so are Direct Each site has a Master and a slave bridge as follows: PBXA (Master) -> PBXB(SLave) PBXA (Slave) -> PBXC(Master) PBXC (Slave) -> PBXB(Master) On PBXA presence works fine with all three PBX's appearing in the client, but for B and C only the local extensions appear. Bridges are all configured the same and user extneion to receive presence are configured. Any help to finally sort this out woudl be greatly appreciated.
