Multicast response from Asterisk

I am trying to come up with a way to have Asterisk respond to a subscribe message on Specifically I want it to send back a 200 OK and then the URL of the provisioning server ie: the IP of the Asterisk box. To my simple mind it should be accomplishable. Anyone out there that might have the smarts to do this? I know there is a out there for SNOM phones but I want to have my asterisk box do it natively if possible. There must be a way.

for any ideas.

There is nothing built in to do this. You’d have to write C code in order to do so, or keep it external.

Ok I’ll keep slogging along on the python script
