[Asterisk-Users] why even use SIP

[Brian G]

After a few years working with various business PBX's, I've found that
users see, feel, and hear the phones.  Assuming that voice quality is
not crap and you have enough trunks available, users will evaluate the
PBX based on their experience with the phone.  I'm always amazed that
even small business that are basically very cheap will pick a higher
quality, higher priced phone almost every time. 

This leads to option4 as there is getting to be a nice selection of SIP
phones available.  Polycom and Cisco phones look and feel good.  I
haven't tried all the other options so there may be a great new option.
