W52H - Provisioning contacts and speed dials

[GIWM]

I realize this is a big ask, but we would like to be able to add contacts and set up speed dials through provisioning templates for the W52H. At our stores, these phones get beat up and occasionally have to be replaced. I like to ship all our Yealink phones direct to the store and simply have them plug them in and give me a call when it boots, at which point I provision it and they're done.

With the DECT phones, there's obviously a bit more setup in general (pairing for instance), but the more I could do through provisioning, the better.

Thank you.
