Hi,


I am trying to add a new gateway to bind the PBX with the MSC on port 5060. Here are the parameters I have:


  • IP: 172.225.10.10
  • Port: 5060
  • Protocol: UDP

I have configured everything on my side, but the status still shows NOREG.


I have checked the routing and confirmed that the port is open, so everything seems fine.


Could you please advise what I might be missing?


Thank you.

In your screenshot, you clearly disabled the REGISTER option. But you only need it when you set up a provider to use registration vs IP authentication. For IP authentication, it's ok to have no registration.
 
Thank you for the feedback.
I think the issue is that the default SIP port used in the external profile is 5080, not 5060. I will ask the provider if they can align with port 5080.
 
The proxy setting controls your outbound traffic. Not inbound. Most providers expect inbound traffic on port 5060.
 
You would need to post a call SIP log to find out. Without logs, your guess is as good as mine.
