Outbound Dialing

Number Format

Calls to DIDWW Outbound gateway should be sent in the E.164 dialing format: country code + area code + subscribers number. Any leading prefixes such as 00 or + will be automatically removed before passed to PSTN. The same rule applies for Caller ID. Correct example:

To: Bob <sip:123456789@out.didww.com> // Called destination number in SIP "To" header
From: Alice <sip:1987654321@Caller.com> // Caller ID in SIP "From" header
