> Call admission control – static bandwidth management

Authentication

> Compliant with RFC 2617 & RFC 1321

> Registration to a Proxy

> Outgoing call with global login per direction

> Incoming call : check on IP addresses / Hostnames via ARS table

Numbering

> Addressing scheme :  user@mydomain

> Format per direction

Security
