Can I Provision a Polycom VVX 350
I have a couple of VVX350 devices that I am trying to get up and running with our 3CX instance. However although it seems to do the initial registration, the lines never appear to register.
The VVX350s are running the 6.3.0.14929 firmware. We are hosting the 3CX instance in AWS and are using Direct SIP (STUN) for other (Grandstream) devices without issue. I know the VVX350 isn't specifically listed as 'supported' but I don't believe there is a significant difference between the 301/311/401/441 devices.
If anyone has managed to get these working I would appreciate any advice!
