- ccm 4.1(3)
- a call from pstn is forwarded to an external phone on the pstn
I need to add a prefix to the CLID sent by the redirecting IP phone.
This is working when I use the External Phone Number Mask, but not when using either the Transformation Mask or Prefix. I tried these settings for both, Route Pattern and Route Group, neither of them was working.
What am I missing?
