I need some help to understand how best to build a Issabel PBX at a Main campus, with several satellite campus connected via VPN, supporting Endpoint Manager to provision phones.
I can scan and see all phones local to the PBX Local LAN, but I can not scan any of the satellite campus LANS and find any phones to provision. I can ping all the phones on the satellite campuses no problem, and I can manually register the phones.
Any Guidance would be greatly appreciated!
