Customer has callmanager 6.1, they have a remote site with analog FXO that subscribes to call-waiting from the PSTN using hook-flash signaling.
On an IP phone (7941), they can hear the audio beep letting them know that there is another call on the line, however I'm not sure how they can signal a hook-flash on that line to actually pick up that second call on that FXO port.
Right now, the port is in MGCP mode, and the hook-flash parameters are configured, but how can the user actually perform a hook-flash from an IP phone?
I saw a post on this a couple of weeks back, and I think it stated that the hook flash functionality for call waiting on FXO lines isnt present in CUCM like it is in CME. Ahh found it..check this link, it has some excellent info:
