Transcript

[slide154] Now, as I mentioned, SIP was designed to be extensible. So one that was added was INFO so now we can send information during a call. Reliable acknowledgements. The SUBSCRIBE NOTIFY for SIP SIMPLE. Refer, so we can now refer a call to someone else. The ability to send messages. And the ability to do updates.
