Running into an odd situation.
Outside calls have dead air and never complete.
We have a setup where the client cannot configure their MBG in Server-Gateway mode due to security reason and politics. The only way around this is using the DMZ profile, but we cannot establish any outbound calls to Twilio. MiVB and MBG are configured per the Twilio CoE document, and the SIP trunk shows a green check mark for the status.
MiVB, MBG and the phones are all on the same network.
Pcaps (on the MBG) show the call setup communications between MiVB and MBG, but we never see the MBG reaching out to Twilio. FW rules are an any-any for the NAT. Tried flipping to 'custom profile' and using the inside ip address for the set-side with the same results.
Thoughts?
