Orginal Calling Party Presentation issue when CFNA

aeriksson · ‎03-05-2010

Hi!

I have an issue with seeing the Orginal Calling Party Number when an ip phone has CFNA set to the mobile.

This customer wants to see the Original Calling Party on the mobile to which the call is forwarded, but all they see in their mobile phones display as calling party is their ip phone number. Have tried to set Calling Party Presentation at GW level to "Originator" and "Last redirecting" but no change.

Any ideas?

Many thanks

Annika

Where are they located?

Nowere in the world except some US telco, PRI customer are allowed to send an arbitrary calling number, that as you can imagine can lead to malicious use.

This practice is now getting restricted in the US also.

In Service Parammeters on the Cisco CallManager service and set Always Display Original Dialed Number to True.

This is in CUCM 7.0.

That does not affect an invalid CALLING number, blocked by telco.

To turn off phone display updates, so the phone displays only the dialed digits, set the Cisco CallManager service parameter "Always Display Original Dialed Number" to true. When this service parameter specifies true, the originating phone displays only the dialed digits for the duration of the call.
