I have a customer who has an old existing phone system. They are interested in going to CallManager 5.x. They want about 35 IP phones, and want to retain their 150 remaining single line analog phones.
THE DLU calculator has values for CallManager needed licenses for the IP phones, but shows the Analog phone licenses needed as 0.
The roughly 150 analog phones will be connected using a series of VG224s. Surely it's not correct that 180 people could be using a phone system, but the only Device Licensing requirements are for the 35 IP phones.
Does anyone know what if any Device Licensing units need purchased for an old single line analog phone?
