VoicePulse trunk working, Cbeyond trunk (inbound) failing

I’ve had a VoicePulse SIP trunk installed and working on a test DID for over a week with no problems. Today Cbeyond installed our SIPconnect trunk for our main office phone number. While my config lets me dial out to the PSTN, all inbound calls to my office number are failing. Calls to my VoicePulse number are working fine.

The peer and user parts of my sip.conf seem to be fine for Cbeyond and I’m registering with them okay.

I’m desperate at this point, so any help is appreciated. We’re running 1.4.18.1

I’m happy to email my config files to anybody who thinks they can help.
