Passing Caller ID through from SIP Trunk
To ensure Caller ID passes through our system from your SIP trunk, please send a 10-digit Caller ID on incoming calls. When dialing out, use either a 10-digit or 11-digit format. Avoid including a leading "+" in the Caller ID if you want it to pass through correctly.
