Callmanager and call waiting on FXO

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?


Re: Callmanager and call waiting on FXO

Hello Michael,

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:

Hope that helped, if so please rate.

We are now running into

We are now running into issues where small customers that are replacing there UC500 with BE6k are in a bind because the feature is missing!

Re: Callmanager and call waiting on FXO

Yep - not supported. Sorry.

If you've got a sales team you can ask them to put a feature request in. It requires people doing this and asking development and making a business case for features like this to be put in.
