Remote Call Control

What’s New?

• Focus draft on narrow subset of problem:– remote answer (use REFER to send 200 OK)– remote reject (use REFER to send 486, 603, etc..)– remote make call (already supported)– remote hangup (already supported)

• (Remove remote hold, etc..)• Use the Target-Dialog header to select

context/session/dialog• Clarify authorization rules: If Referror and the

Referree use the same identity/credentials, authorize the REFER.

Issues / Next Steps

• Draft edited by Cullen while on drugs (wine)• Much copy-editing and consistency needed • Examples and Normative sections need to reflect

use of Target-Dialog header described in Overview• Needs IANA registration for response param and

option-tag

• This is obvious. The MBUS approach is harder and has not gone anywhere. Can we please just do this?
