[Asterisk-Users] why even use SIP

[Michael Graves]

I'd look at the Polycom IP300 or IP500. They do an awfull lot for under
$200 each. Moreover, you'd have multi-line capability, transfers,
conferencing on-phone, etc. They are provisioned centrally from an ftp
server and easily configured. You can can also power them over
ethernet, which would eliminate the gaggle of wall-warts that the
Sipura's need. 

You might also consider the Sipura IP phone, although I have no
experience with it. It's supposed to be a two line phone.

I just think that an all-digital solution is way more promising in the
long run. Worth the effort, even if the initial cost is slightly more.
