[Asterisk-Users] Concept for line appearances and bridging: anyone?

[Steve Towlson]

In order to try and keep some standardisation in Bridged Lines implementation on Asterisk using SIP, you should look at the following IETF draft.

http://www.ietf.org/internet-drafts/draft-anil-sipping-bla-01.txt

There is work in progress within the SIP community on Bridged Lines, and there are already a number of end point implementations using this draft.

MGCP may have this feature, but Asterisk should be able to provide 
this functionality on any channel type, not just MGCP.  The fact that 
we can manipulate the audio on the server with * implies that we can 
mix any two channels in an arbitrary way.  This implies (of course) 
that we keep the audio channel going through our * server, but for 
most PBX environments this isn't a concern, and in fact is a 
desirable goal.
