Solved 503 Transport failure: no transports left to try/REGISTER from local

[snowmark]

I have spun up a V18 system hosted on a Win10P PC.

When trying to add SIPs, I have a FAKTORTEL SIP that registers but a MYNETFONE SIP that errors with the above message.
The SIP credentials have been working with a stand alone YEALINK phone but will not register with the 3CX system.

Help please!

Regards,
Trevor

Did you follow the guide? Because it appears you are trying to register and the guide says it should be IP authenticated:

Apologies for delay in replying and thank you for your assistance. What eventually worked was in another thread where I set Generic country and generic SiP trunk.- registered straight away. Dumb of me not to see or think of that! - all power to you..
