I have a customer who is going to buy an IP Office to replace a 15 year old Magix for about 70 users. He currently has one site and will probably always have one site. There are a few managing partners who could possibly use connectivity from a home office - no more than 3 or 4. Out of habit I guess I mainly use digital phones. The IT guy here - who I have known forever and would consider a friend - really seems to want a reason to use IP phones. Generally, with a new system in one site, which is better? Is there any advantage to going IP for everyone vs. a mix of digital and IP? Just looking for opinions...
