My company is interested in purchasing a Cisco IP phone system. We currently have a Nortel PBX with about 100 Nortel 2616 phones.
My question, is there an adapter or interface that will allow a Nortel 2616 phone to be used with a Cisco IP phone system?
I know Cisco makes ATA adapters for analog phones, but what about digital phones?
Or do I have to replace all 100 Nortel 2616 phones?
