ISDN SIP Privacy call fails

Hi,

We have a customer that has a problem with incoming calls (ISDN) that have a restricted calling-id (private calls).

Such calls to a private extension work, no problem. Call is announced as "Anonymous".

When the private extension is forwarded to an external location the call fails.

My guess is that CUCM doesn't know the call is private. The SIP debugs do not show any "privacy" attributes except for the name "Anonymous".

Is this normal?

IOS 12.4(25b) on a 2800 series router.

Regards,

Erik Tamminga
