By default RingRx service enables all US and Canada destinations. If you need to dial outside that, you will need to contact support to open up full international dialing.
Dialing US & Canada
You can dial any US or canada number by 7, 10 or 11 digit.
7 digit dialing:
If you dial by 7 digits, we will presume the number you are calling is in your area code and prefix it with the areacode of your callerid.
10 digit dialing:
If you dial by 10 digits, we assume the number is a US domestic number
11 digit dialing:
If you dial by 11 digits, this is a fully formed US domestic number and we will route exactly as dialed.
If you have enabled international dialing, RingRx only supports dialing with the US international dialing prefix of 011.
