The excellent guide I found says that the configuration and setup
is extremely well documented for this model of Cisco IP phone. I
also read that I can google search for SIP firmware and download
them?
<br>
<br>
Is Cisco 7960 better and more advanced than Cisco 7940?

You may end up with one used with Call Manager, and struggle to
get
<br>
the SIP firmware for it.
<br>
<br>
In addition there were several versions of SIP firmware.

None of the code will be available to you without proper
credentials

from Cisco

<br>
Good day from Singapore,
<br>
<br>
Today 18 December 2020 Friday, I found an excellent guide on
<br>
configuring Asterisk VoIP IP PBX SIP server with Cisco IP
phones. I
<br>
think the author explains very well and very clearly. The
guide is
<br>
certainly very detailed and well written.

I am going to buy a cheap and used Cisco 7940 or 7960 IP phone
for
<br>
about SGD$20 and configure it to work with my FreePBX 15 and
<br>
Asterisk 16 PBX appliance by following this guide. I will
provide
<br>
feedback and my own custom guide after I have done so.
<br>
<br>
I just want to share this very excellent guide.

On the front page, it says:

Sharing is caring.

Thank you.
