I have played around with the Sangoma P370 for some time and now I have a P330 too. Why is https for phone apps a requirement and not just an option? The problem is that in some (network) settings it just isn’t possible to resolve the FQDN to a local ip and you can’t get the phones to work. To be precise, the P330 just needs it for the queue app…yet the P370 has no phone apps at all.
Why don’t you (Sangoma) just let the user decide? In a local network without any port forwarding (phone system, phones) there is no need to fool around with certificates etc.
But maybe I am wrong…
