Hi @jaisonmonson , I assume the MX68’s are registering fine out to the Meraki cloud and it’s just the phones not registering correctly?
Are there any DHCP options that need to be set for the Polycomms require to register out to the PBX/Cloud? Issue looks to be around registration, have you ran a packet capture on the phone port?
