In my network, I have each phone is a sip peer. Each extension is setup with an a,b,c,d equivalent. So, if my extension is 2345, I have 2345a,2345b,2345c, etc… And all the 2345 extensions ring at the same time. What happens is that if I ring 2345 and 2345a,b,c aren’t registered, I get an error and a warning for each extension that isn’t registered.
I am looking for a way that I can programatically determine if the extension is registered and if so send a call there if not then don’t.
I have been looking at groups, chanavail and others. I am not finding anything that really fits the bill. If someone could point me toward a link or white paper or cmd It would be appreciated.
Thanks a lot,
