CPCP Issue 8: Re-inviting/re-referring participants that dropped out or did not answer Participants can drop out of a conference for many reasons including: client crash, out of coverage, had to leave for a while. Proposal 1: Modify the conference policy by placing the same user again on the dial-out list. I.e. replacing the exiting entry for that user with exactly the same information. This triggers a notification that a change was made. This might not work will all transport protocols Proposal 2: Introduce an attribute into every target-uri in the dial-out list, say 're-invite', that has an integer value. When a user is needed to be dialled again, the 're-invite' value is increased by 1. The focus realises that 're-invite' value has increased and can then re-invite the user to join the conference. eg: The DL looks like the following and Alice has dropped out. Her entry in the DL is replaced by increasing recur to value 2. The focus is triggered, realises the change an re-invites Alice. |
