Repurpose old Mitel phones?
Current have a Mitel 3300. 75 IP phones (6920/6940) and 80 analog phones (hotel rooms with cat3).
Time to go cloud. Need ATAs to convert analog to SIP.
Can any providers reuse our Mitel phones with custom firmware? I’m guessing no, but thought I’d try.
Current leader is ESI. Any others to look at?
