Receiving a call is easy to understand and we can implement on the phone. How about initiating a call from different line, because there are two cases: 1) Initiate a call from the same phone by selecting line 1 2) Initate a call from the other phone with same AOR registed by picking it .
Here is one question: How to join another call to one group call such as conference. For 1), it should be easy. But for 2), if without help of proxy server, I can't figure out how to make it. Thanks a lot. -Regards On 9/25/06, Paul Kyzivat <[EMAIL PROTECTED]> wrote: > > This is much easier to implement than single line extension. > > A phone that is registered for some AOR will typically receive invites > for calls to the AOR whether it is currently in a call or not.
