Hey Matthew,
Good question, you will need to add at least $10 in order to test the system. If it won't work for you we will refund your account balance.
You can test your system one of two ways, prior to porting a number.
1. Buy a new number for testing purposes (you can release later, and they are fairly cheap)
2. You can assign your current phone number to RingRoost prior to porting it here (
https://www.ringroost.com/account.php) ->click "Assign a Number to RingRoost".
- You can then test your configuration if you have a SIP enabled softphone (we recommend Linphone) that allows you to dial a sip address by dialing:
"sip:{yourphonenumber}@ringroost.com"
Thanks,
RingRoost Support Team
