Calling to Internal numbers

With Vamos you can also use your mobile phone to call your colleagues using a short internal numbers, such as 381. However, there you need to keep the following restrictions in mind:

• 2-digit internal numbers can give problems because they can conflict with specific MMI codes

• internal numbers starting with "00" will not work as this is seen as an international access code and is replaced by "+". For example, 0002 is replaced by +02.

• 4-digit internal numbers starting with "0" will not work as this replaced by "+". For example, 0444 is replaced by +444. 

• special reserved short numbers such as 112, 18xx, and 14xxx (x) cannot be used as internal numbers.
