SIP Authentication for Jabber clients

[ksherman]

What protocol does the Jabber client use for SIP authentication?  I assume it's using HTTP digest based authentication per the SIP standard.  Is this true?

[scoglass]

SIP authentication typically occurs over port 5060 (TCP, UDP, SCTP) or securely over 5061 (TLS) as per RFC3261 regarding SIP as a transport.

Cisco follows these same standards and refers to the ports used for SIP communication in the Jabber Video Admin Guide.
