Blocking transfers on calls to a specific line

[aarondyck]

I have a customer who wants to block calls coming in on one specific analog trunk from being transferred to other users - the live answer version of an information mailbox, if you will. The user answering calls on this line is also required to answer calls on other lines that can be transferred, so I can't simply bar the extension range. I don't believe any kind of appearance will work as they should follow the programming of the set they terminate on.

I found documentation saying that there is a limit of 10 forwards per call. If I were to use phantom users to forward the call ten times, with the tenth forward terminating on the answering station, would this prevent the call from being subsequently transferred? In other words, do transfers count towards the forward count?

I guess transfer and forward do not correlate with each other.

I don't see any why how to accomplish this. Besides an analogue phone as target with a mechanical locked transfer button.

Transferring calls between users is one of the key functions of a PBX.

Need some help with IP Office?

Like Derfloh said, you can provide an analogue extension for this type of call. Modify the flashhook pulse width so they can't obtain secondary dial tone to transfer the call.

But really, this is like Amriddle has always said, using technology to overcome a human problem. The best thing to do is to have their supervisor instruct the user not to transfer the call.
You can use ACR to identify if calls continue to be transferred.

Depending on the URI configuration the ICR can be completely ignored.

If your URI is configured to use internal data then the IP Office will look into the user's SIP tab and if you have *'s it will look into ICR.

A madman with a taste for speed.

Thanks, guys. I figured that was the answer. I modified the ICR to display a Toll Free when calls come in on that line; hopefully that's enough for their staff to figure it out.
