[Asterisk-Users] Copying SIP Subscriptions

[Douglas Garstang]

Thanks to SER, each of our Asterisk servers knows the address of every phone. Any asterisk system can terminate a call to any phone. So, all we would need would be for the asterisk system that terminates the call to also have a copy of the subscription, and voila... it sends a NOTIFY back to the phone (well actually it sends it back to SER cuz that's where the SUBSCRIBE came from).
 
Actually, while the above is true, I'd really like to get rid of SER alltogether. It's just an extra moving part that can break. 
 
So.. I don't know. Unfortunately Asterisk is really lacking in this area. It'd be great if there was some way to distribute registrations and subscriptions between a cluster of servers. That would rock.
 
Doug.

	 Not presently, no. But I guess the second side of this would be, if
	we were to copy of the subscription, how would we make it of use on
	the second system? would it then have to broadcast state information
	about the devices it was watching on system A on to system B?
