The following dialing rule is the default for your Softphone settings:

Maximum length of internal telephone number: 5

That means for all telephone numbers with more than 5 digits a prefix of “0” willautomatically be added for the outside line.

If for example you have 3-digit internal telephone numbers (extensions) change the length of internal telephone numbers to 3.
