Dialed number Display.

[firmtel]

When we get incoming calls we can see the caller id from the persone who is calling in our Display.

We are using a pbx where we have multiple phone numbers connected to one device. Can we somehow display the number that the incoming person has dialed in the display? Now i can't see if people dialed my work number or private number.
I'm 99% sure the information is send in the sip header but the phone doesnt display's it.

It's a T46G where using

Thanks in advance
