Getting Forwarding station from PSTN call

[bdecout]

Is it possible to get the Forwarding Station # from a PSTN incoming call?

I'd like to forward my cell phone to my PBX and see its number as being the forwarding station when sobebody calls it.

In unity call viewer, I can see a # if I use an internal extension to forward the call to VM, but If I send the call directly from the PSTN to Unity, this field is blank.

Should this information be passed by the telco or not?

Thanks

Yes, your TELCO should be sending you this information using the Redirected Dialed Number Information Service (RDNIS) field in the setup message.

Also make sure that your PBX is capable of supporting RDNIS.

We are using Callmanager 4.1.3 with H323 AS5350 PSTN Gateways.

That's probably something I have to setup/enable somewhere.

I don't see that info in the Q931 messages.
