The new feature
'Disable/Enable Call Waiting for one call only' has me wondering how either form of Call Waiting (persistent or one call only) works in this arrangement.
Scenario: I make an out going call using SP1 which uses GV. My SP2 is CallCentric, I have call forwarding setup as explained here (this works great BTW). Both SP1 and SP2 use port ph1. Therefore all incoming calls, even those to GV come in on SP2
On an analog handset connected to ph1, I have some speed dials setup using *56 and *57 as a prefix (*56 and *57 is Enable and Disable Call Waiting). But that disables or enables Call Waiting on the outbound call on GV. When someone calls the GV number, it routes to CallCentric on SP2, and rings as a call waiting call on ph1? I think I saw that exact behavior yesterday.
How would one send the *57 or *56 to SP2 when making an outbound call on SP1? Something tricky in a digit map somewhere?
EDIT: I just used this feature, and I see that doing *57 on an outgoing call on SP1 disables call waiting on incoming calls on SP2. I take that to mean the *57 code applies to the physical phone port and also to any SPs routing calls to the port. So my question is asked and answered.
