My carrier (SIP Trunk) states I have Call Transfer yet on my Norvaya BCM (Business Communications Manager) I was not able to do a hook flash on the SIP trunk via the actual hook switch or Feature code 71 (Link/Flash)....on hook switch method call drops right away where the Link/Flash code of Feature 71 does nothing at all.
Hook Flash works fine on the POTs line we have.
The carrier states Hook Flash is the only way to do Call Transfer.
I deregistered the BCM and tried a Polycom 670, it how ever does not have a Flash button.
Transfer button however did work.
What is the Transfer button actualy doing?
I have searched all and there is no talk about hook flash and Polycom sets except for some anlog conference unit.
Thanks
