[Asterisk-Users] Need help understanding SIP phones

[Jeff Donovan]

Greetings

i have been using asterisk with good success with soft phones and I 
need to purchase some Sip capable phones to test.

How would/do vendor specific phones like cisco 7900's and 3Com VCX 3100 
series phones work SIP to SIP if they download the protocol from the 
Vendor call centers?

I want to build my own with Asterisk, and use different phones. They 
say they are RFC 2543 compliant. Can you download the software and tftp 
to the unit? How does it work?

any insight would be helpful.

Thanks
