I'd like to have some help of you about the best strategy for creating a global DialPlan for my company. I was thinking about creating a 7 digit dialplan (3 for country code and 4 digit extension)..
We already use a 4 digit extension in the main site.
For dialling to other branches we're using:
Example for Portugal: * 351 22 xxxx
Example for USA: * 1 678 xxxx
