Very useful

Our team use the SDK of this team and it’s very useful.
In other order, we have an issue with IPv6 and T-Mobile with the SDK that can’t register.
If you can help us, will be a great help.
Best regards.

Needs a bit more

Great for my purposes. Needs speakerphone, dark mode, full size keypad on calls and to be able to hear the touch tones when you press them.
