Responding in the hope that someone has the time to help me with this.
Good morning @TMUS, welcome to the Community!
I sincerely apologize for the belated response: your topic was categorized in our mobile section. Which VoIP client are you currently using?
You could try the setup in these topics:
(You can find the specs under “VoIP (Vast Bellen)”)
and:
I have translated the VoIP part:
“You can set your own SIP password in My T-Mobile Thuis. Because you have to explicitly agree to the risks involved, we will not do this for you. We do not know and do not provide the original SIP password, you have to look it up yourself.
I hope this helps speed up the process!
@Pieter_B I know I've been requesting your expertise a lot recently, yet you're one of the most insightful users when it comes to port forwarding: could you take a look and see if there's anything we've missed? Thanks in advance!
@TMUS
Are we talking about a VoIP client or a VoIP server?
For a VoIP client you do not need any port forwarding, because it behaves more or less like a web browser does.
If we are talking about a VoIP server, then indeed you need port forwarding so external VoIP clients can reach the server.
I also have a VoIP client device without any port forwarding setup, but the only thing i did , use an alternative ports away from 5060. My clients is running via port 5070, because my VoIP provider has that alternative port available for registering.
Hi @Jason and @Pieter_B ,
Thanks for your responses here.
It concerns a Mumble VoIP server. I am using the default Mumble port (64738), but that’s not 5060, like Pieter mentioned, so I assume the port used isn’t the issue. Similarly, I assume this has nothing to do with SIP, right?
Hello @TMUS
Using an alternative port for your server shouldn't be the problem I guess.
Is the device where you are running the server on directly connected to a LAN port of the Zyxel?
@TMUS
So it is a VoIP server, with a dedicated port. Then you do not interfere with the normal VoIP’s out there on 5060.
I was watching a YT and this guy is talking about that there is a ‘public’ setting you should change, did you check that setting is correct?
But i am not a specialist with this application, but it might be so that if not ‘public’ the application might not respond the way expected.
For the rest it should be a very basic port forwarding of your configured port in the application.
