could you please include the full sip trace of the call from the drachtio.log file?

[dvillaume]

Sure, drachtio-siprec-docker-logs.txt

[davehorton]

The body of the invite got truncated, and I'll need to see the full invite from broadworks

[davehorton]

also, given the length of the INVITE request you may want to use sip over tcp rather than udp. If you use udp, then make sure to increase the mtu per https://drachtio.org/docs/drachtio-server#udp-mtu

[dvillaume]

drachtio-siprec-invite.txt I did switch to tcp, please find attached the full message

Thanks

@dvillaume U can test if message is correct via parser.js in test dir

[dvillaume]

Hello, thanks for your return. i'm unfortunately unable to test it in my environment anymore. i close the ticket.

@dvillaume Why? You have Broadworks' message and parser.js :)
