Snom M500 & M55 with Hosted 3CX PBX does it work?

Hello everyone,

i have a customer who wants a Snom DECT M500 Repeater & the M55 Phones.

3CX hasn´t a template for M500.

Does anyone have configured a M500 with hosted 3CX PBX? Or do i need a custom template?

The 3CX Support tells me it should work with selfhosted 3CX & custom template. But it´s not supported.

Regards
Kevin
