Call Waiting Tone that caller hears

I found various conversations about this topic but without solution.

All my users want that caller hear a different tone when called user is busy and can?t hold the main call on hold.

For example, a secretary want to tranfer a call for someone but she don't have a monitor key for this extension. Then if the called person can't hold the first call the secretary could say to the costumer that X person is outside the office instead that call in a few minutes.

Some ideas?

Hi,

I have the same issue. Did you manage to get this working? I would appreciate your feedback

I had to write a TCL/IVR service to do that:

It works with CME and should also work with CM when H.323 or SIP is used (NOT MGCP).

It doesn't handle transfers yet but I will add that shortly.

Hope this helps, please rate post if it does!

Thanks for your response. This would work also for internal and external calls. I was actually looking for a simpler solution, like a beep tone on the caller phone. I am surprised that CM does not do this simple thing. So for your script to work i should disable call-waiting on the Call Manager right? What would be the ultimate is to have the option for call-waiting and the second caller gets a beer sound indicating that the called number is on the other line. With your solution the call will not present to the called phone right?

Thanks,

Hi, this is explained in the script itself, however the way I think should work with the CM is that you set busy-trigger to 1, CFB to the service number. Then you have to configure "auxiliary DNs" for all the extensions where you want the service. Caller will hear an announcement about the extension being busy. Called will see the call coming on the auxualiary DN and can pick it up anytime.

You can also distinguish between external and internal callers by mean of calling number.

I understand that it may seem a little complicated but is the best I could come up with.
