Introduction
• UA Configuration and Management are different– SIPPING-CONFIG and XCAP address SIP UA
configuration– SIP UA Management is typically done via CLI, HTTP,
SNMP, etc.
• Focus of this presentation:– How do we perform management of SIP UAs behind
NATs and Firewalls?– Use Case #3 in

Requirements
• Define SIP-based mechanisms to enable establishment of management sessions with SIP UAs– Specify methods to initiate management sessions– Specify semantics to indicate session parameters,
e.g.• Management protocol type (e.g. HTTP; CLI or SNMP over
suitable transport like ssh)• Other parameters (initiation time, duration, periodicity)
• Ensure mechanisms operate in the presence of NATs & Firewalls
• Thoughts?
