SIP trunking problematic
•
NAT traversal for SIP
–
–
•
Network & SIP Communication security
–
–
•
NAT resides at L3 – SIP at L7
NAT processing “breaks” SIP addressing
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
