401 Unauthorized Forwarding Registration From SBC

Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

3. OS type and the version: 4.9.0-8-amd64 #1 SMP Debian 4.9.144-3 (2019-02-02) x86_64 GNU/Linux

4. UA (phone), gateway or other hardware/software involved: FreeSBC, standard yealink voip phone

5. Your problem: Hi all, I've got quite an intricate setup in terms of about I am forwarding my SIP requests to the Brekeke sip proxy. Essentially we have an SBC that routes our calls and forwards SIP sessions/registrations to a proxy. The request comes in on a public interface on the SBC and forwards to a sip proxy. We've been successful doing this with Asterisk but not with Brekeke as yet. We can register a phone directly to the IP of the brekeke server but we cannot do forward registration using DNS names. It comes back with a 401 unauthorized every time we try and there is no indication in the logs as to why it gave us the 401. Please can anyone advise here as to what other reasons we get a 401 besides username and password?

Let the SIP server knows the DNS name.

Add the same DNS name in SIP Server's [Configuration]->[System] page -> [Interface address 1 ], and restart the SIP Server.
