Request for Guidance on Connecting Cisco 7821 Phones to Asterisk / FreePBX

I have Cisco 7821 phones and I want to connect them to Asterisk, or in common terms, to FreePBX. What should I do for this? I created and tried many scripts for them, but unfortunately none of them worked. If you could guide me step by step, I would really appreciate it.

What aspect are you having issues with? Configuring the phone itself? The Asterisk configuration?

Have you tried google “register Cisco 7821 to asterisk”? Cause you will get a lot of valid information…

i.e. How to Register Cisco 7821 to Asterisk Server |

Oooh, how wonderfull is google, or any other search engine…

No, my issue is only with the phone configuration. It needs to be integrated with Asterisk, but even after creating some configuration files and scripts for the phone, it still did not work.

dose it work with my Phone model?

I don’t think this is suitable for Asterisk; it is specifically designed for CUCM.

What do you mean with “Its needs to be integrated with Asterisk”?

The manual I linked in my reply shows the configuration of the Cisco phone.

What have you tried to do?

I made these scripts before and tried them, but they don’t work properly.
The phone is still stuck on progressing.

Then it is an issue with the Phones, maybe the Cisco forum can help you.

I have a whole fleet of these phones registered to a FreePBX server. In fact I have both Enterprise firmware phones and 3PCC firmware phones registered to it.

I have often helped people get these phones working with FreePBX in the FreePBX forums. If you go over to Endpoints - FreePBX Community Forums and post your request there we will assist you.

Very few people in the Asterisk forums work with these phones on a regular basis and fewer here really care IMHO.
