thinQ uses the following error codes:
|407||Proxy Authentication Required (Build a Trunk authorizing your switch IP/Prefix)|
|403||Forbidden (Build a Trunk authorizing your switch IP/Prefix)|
|503||Channel Limit Reached (You are out of call paths)|
|503||Route not available|
|503||Funds Required (Top up your thinQ account)|
You should configure your switch to route advance to another provider if you receive any of these codes to avoid service issues. Contact your account manager if you receive a 503 Funds Required or Channel Limit Reached message as we may need to change the parameters on your account.
