[Asterisk-Users] ADSI phone vs. IP phone

[Ken Alker]

Assuming the price of an ADSI screen phone (say, Aastra 390) was the same 
as an IP screen phone (say, Cisco 7960) and someone was setting up an * 
server for their 20 employees (each of whom would have either an ADSI or IP 
phone on their desk), would there be advantages to using the ADSI phones 
over the IP phones, or vice-versa?  For discussion, let's assume that the 
hardware needed to patch the ADSI phones back into * was not a cost 
concern.  I'm looking for differences between the technologies independent 
of cost.
