Call forward show wrong telephone number

[Jochen Brenner]

Hello everybody,

I have a problem with our UC520. I set a call forward on my company phone to my mobile phone. When I call my company number I forward to my mobile phone but my mobile phone show the wrong telephone number. I can not see my own number but I see our company central number +49 01234 / 11111 0.

Can I change this configuration with the CCA?

Hi,

this is a normal behavior in germany.

you have to call your isp and ask them to activate clip no screening in pri interfaces.

Hi,

ah ok. Thank you!

[Jochen Brenner]

Hi,

is that only a configuration change at the isp? I have called with the isp and he give me an information that we must activate also on our uc520?

EDIT:

Or is this feature enabled at default?

Hi,

this is an Feature set on Provider set only. We can't configure that in CUCM / CME etc..

Cheers,

Stefan
