Have setup a Jabber server on a Linux server and am unable to receive communications from Cisco UC Jabber users once I request to add them as a contact. Example, once connected via any client to my Jabber server, I add a user email@example.com and it sits at pending. The user firstname.lastname@example.org does receive my request, and accepts. I never see anything in return - is there some simple setting I need to enable for 2-way communication between servers or is there something else going on?
What ports/protocols should I expect to be in use from Cisco Jabber that Cisco employees are using?
Thanks for the info but it seems this isn't the problem. I am able to communicate to any other Jabber server except Cisco UC. Have an @cisco.com user who is telling me I am always "Unavailable" - seems like there isn't communication between the servers.
Confusing since again, have tested a few other servers in the world and communications work fine - network connectivity is not an issue in these cases.
I'm listening on 5222 for client to server and 5269 for server to server. Is it some sort of valid SSL requirement perhaps? The SSL certificate on my server is self-signed.
