SIP Trunking Troubleshooting

Half of my Inbound SIP Calls are failing

Make sure you are accepting calls from all the IPs listed above. The most common reason for a failed inbound call is that your system is rejecting calls from a few IPs.

We can not make outbound SIP calls.

This can be because of some missing configuration or wrong format in SIP Signalling:

• Make sure the IP you are sending calls from is added to your account.

• While adding the IP address, make sure Termination is Enabled. Based on those settings, we decide whether calls will be terminated or not.

• For the USA and Canada call must come with a "1" Prefix + 10 Digit phone number. Example 19499300360

• For International, it should be 011+Country Code+Phone number.

International Calls are Failing

For Security and Protection, by default, international calls are disabled. Contact your Account Rep to allow international termination.

I can make only 1 Outbound Call

There are certain limits on a new account. We would like to know our customers, how they would be using the platform and for what use cases. This allows us to understand your needs and helps us keep our environment safe. Please contact our sales team to remove the limits.
