asterisk users - Dec 2020 - I found an excellent guide: Configure Asterisk VoIP IP PBX SIP Server with Cisco IP Phones

The 7940 has 2 line buttons, the 7960 has 6 buttons

There are other versions similar, including the 7970 with a color screen

Not really sure you will have access to the SIP firmware without some
relationship with Cisco.

Better check before poring money down a rat hole!

Also, you will need a TFTP server working on your Asterisk box


Good luck

Thank you for your advice and caution.

I will install a TFTP server on my Asterisk PBX server, according to the 
guide I mentioned earlier.

My suggestion would be to get a refurbished Polycom VVX 301 phone (With power
brick if no POE is avaiable) for around $27 US.
