Got a new one I’ve never run across…
Trying to configure a SIP trunk on a box in Tyler, TX, with Level 3 SIP trunks, Level 3 is using Broadworks backend, they do not allow trunk registration but require authentication on each and every outbound call. For some reason when Asterisk places out bound call, the far end sends us a 401 unauthorized to which asterisk simply replies with another invite, with no auth info included… what other info do i need to provide to get some ideas on this??
