Call full external Number from Intern

Hi,

since this week I am playing around with FreePBX. I already configured a few Cisco 7911 and Cisco 7962 IP Phones via Endpoint Manager and it works very well.

Now I included an LDAP Directory on my IP Phones. The Problem is, in this directory the Numbers are written out complete, including area code and company number.

Example:
+49-543-5766-632
<+49>-

Is it possible to cut everything from the number and just call the extension and handle the call internal?

Greetings
Tobias
