SIP trunking problematic

• NAT traversal for SIP– NAT resides at L3 – SIP at L7– NAT processing “breaks” SIP addressing

• Network & SIP Communication security– Physical medium is the IP pipe – Firewalls control what goes in or out such pipe

• SIP Protocol Normalization & translation– Not all SIP are created equal … and compatible– Open Standard …open to interpretations
