Hi all, brand new install of v15.5 bringing a client from another system. we have @ 70 Polycom VVX 500s. When I goto 'add' the phone and put in the MAC address and click OK the window doesnt close it just sits there. if i change it to Aastra with the same MAC it accepts it and puts it into the extension. I happened to notice as well that under the provisioning folder i do not see a MAC.cfg file we are coming from asterisk systems so Im expecting to see config files here either way I would think? thank you!
