Cannot get phones to register

[JRam]

I have tried both Fanvil and yealinks. I set up the phone via autoprovisioning but they fail. I can see a multi cast SIP going out to 224.0.1.75 but there is nothing in return. can anyone explain what should happen when we try to register phones?

The initial setup was for a different system and is irrelevant to this

I definitely had this working vis Local, but now when reading the guides it appears that this can only be used when you have a local 3cx server or an SBC. If that was so how did it work in the first place.

Anyway. It appears that I can only provision this using STUN?

Hi @JRam

It appears like the phone firmware is a bit old. Make sure it gets updated before trying to provision it

Local will not work if your PBX is in the Cloud and the phone is in some other remote location.

Only a site-to-site VPN would allow it to work properly in LAN mode
- OR an SBC
- OR STUN mode
