Where to put User name and password?

Does not work for me --- where do I set the password of the phone?
(i Use GXP2160)

You don't. It's hardcoded in the extension to "admin". I'm working on a PR to fix this.

Also i don't think your phone supports the make_a_call method: https://www.grandstream.com/sites/default/files/Resources/CTI_Guide.pdf

Wait, i was wrong, your phone totally does support it, but the syntax is different than this plugin uses, and you need to enable it first. see attached.
