[cisco-voip] External Phone Number Mask not recognized

[Kalle Tetto]

Hi,

I would like to surpress the internal DDI on some phones, therefore I 
use the External Phone Number Mask on a line and put the number to send in.

Unfortunatley this does not work with my actual CCM setup 4.2(3). I have 
used it so many times before and it has always worked. But not in the 
actual setup. I can also see the changed DDI in the upper row of the 
Phone correct?
Any ideas, is there a special option in the general Call Manager setting 
which I miss?

Cheers
