I’m using Asterisk and FreePBX 184.108.40.206 with pjsip. I originate outbound calls (no inbound) and my Request-Line URI on outbound calls looks like below, missing the user part with the phone number in front of the IP address
INVITE sip:ServiceProviderIPAddress SIP/2.0
To: <sip:1234567890 at ServiceProviderIPAddress>
The sip trunk require no registration, or authentication, Service Provider enable access by ip address.
Calls complete fine but the Service Provider requires the Request-Line to be like To header and include the number. Where should I look to correct the Request-Line?
