Our system is currently designed for 10 digit numbers only based on the way they are stored.

We can add the suggestion to the list for future release. One of the original decision factors was limiting abuse. Many users say they did not make international calls when they did and if we allowed it in speeddial it would be a lot easier for someone to claim they "accidentally" dialed an international number since it could be a 3 digit code or something similar.

With VoIP fraud is extremely high so we have to design our system to limit it.
