I've played around with this patch and it works well. The only problem I
have with it is related to load issues. The approach used creates an extra
channel to do the real-time call control, so for example if two SIP
channels are bridged on a call the patch would create a third channel to
execute the AGI application and update the original SIP channel timeouts.
The load implications of this have me a bit worried as channels are not
light weight.

I have written a new patch based on KNK's approach that replaces the extra
channel and AGI approach with a Curl and scheduler approach. This lets a
single thread do the real-time call control for all in progress calls and
should mean the real-time call control mechanism has a negligible increase
on system load. In case it's useful I'll upload the patch once I've got
diff working properly.
