[asterisk-app-dev] ARI + Call Transfers

[Joshua Colp]

Greetings everyone and welcome to 2014!

Now that Christmas and the holidays have passed I thought I would send 
this email out to elicit some feedback.

I'd like to enable transfers in ARI. You may think to yourself "they 
were disabled?" and the answer would be yes. The trouble with enabling 
transfers is properly conveying that a transfer has occurred to the 
parties interested. This is due to the event in question being published 
on the bridge involved instead of on the channels. This can be overcome 
for ARI though! Have no fear.

After going through many ideas I've settled on a somewhat simple 
solution: If an ARI application is subscribed to *any* object (such as 
the bridge OR any channels) involved in the transfer then it receives 
the applicable transfer event (blind or attended). The transfer events 
will convey the same information as the AMI ones do and will have a 
guarantee that only one transfer event is published to the ARI application.

Thoughts?
