ahhhhh, I can't seem to get the XMPP to work with Zoiper windows desktop application or android application either. The SIP connects just fine, on both extensions, makes all calls, everything is solid there, but every time I try and send a chat thru zoiper, it says:
Sending message failed: Hey there (cause: service or option not implemented, unspecificed)
I have the XMPP domain set to the hostname of the server, and its enabled on the user accounts in FreePBX, passwords resubmitted as required, chat still doesn't work, any thoughts there?
