What Protocols Do We Have?
Protocols:
• H.323 maturing
 scalable, reliable, mostly positioned in backbone
 approximately 90% of VoIP ports and growing video ports
• SIP in late experimental stage driven by promise of enhanced
services

• MGCP introduced at edge
 “standard” protocol between softswitch and endpoint
No clear protocol “winner”
future networks will be multi-protocol
