Call-through from Cellphone (DISA) shows Cellphone Caller-ID rather than PBX Caller-ID


Recommended Posts

Dear Members,

 

we have the problem exactly described in the Release Notes 3.1 to be fixed:

 

"Also, when the cell phone was used to place an outbound call, the PBX sometimes presented the Caller-ID of the cell phone, not the extension. The purpose was to hide it. That was fixed, and now users can use their cell phones to place outbound calls and present the caller-ID of the PBX."

 

If we use the DISA-Feature (Cellphone calls PBX and make external call through the PBX) the Caller-ID of the Cellphone is sent. We tried to set the Extensions-ANI with the PBX's Caller-ID, but this do not prevent to still send the very secret Cellphone-Caller-ID.

 

Any idea?

Me either and it's really bad as I don't want my cell being published. Hopefully it's fixed soon.

Poor workaround:

 

Create a trunk, register a extension at this trunk (loop connection), dial out over this trunk so you'll present your office trunk number and no longer the Cellphone's. Disadvantage: Increased Echo.

We have added an additional header called "Related-Call-ID" that makes it possible for the service provider to verify that we are not spoofing the Caller-ID and the outbound call "relates" to another inbound call. AFAIK callcentric.com has already happily implemented this and their customers can enjoy a proper and safe cell phone redirect.
