SIP as an Enhanced Services Protocol

• Open, simple, extensible, and lightweight protocol

• Internet heritage easier to integrate with
  telephony

• Already implemented or planned on most
  softswitches and gateways

• Allows control of bearer path

• Supports multiple call legs (i.e., forking)

• Same protocol used between services and call
  control entities

Summary

• Enhanced services are key to the success of
  packet telephony

• SIP application servers can be used to augment
  entities providing basic call control functions

• SIP application servers can be used across
  different architectures (H.323, MGCP)

• SIP is a simple, open, and well-defined interface
  encouraging third party application services and
  vendor independence
