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

I am going to buy a cheap and used Cisco 7940 or 7960 IP phone for
about SGD$20 and configure it to work with my FreePBX 15 and
Asterisk 16 PBX appliance by following this guide. I will provide
feedback and my own custom guide after I have done so.
<br>
<br>
I just want to share this very excellent guide.
<br>
<br>
Another excellent website is <a class="moz-txt-link-freetext" href="https://www.voip-info.org/">https://www.voip-info.org/</a>
<br>
<br>
On the front page, it says:
<br>
<br>
"Welcome to VOIP-info: a reference guide to all things VOIP."
<br>
<br>
Sharing is caring.
<br>
<br>
Thank you.
