So far i always used Freepbx with soft phone extensions, today i would like to add Avaya 9620 phones to my installation and use them as extensions.
Since i never did it, could you please explain me steps to do so ?
I read that phones should be use SIP firmware, i don’t know where to find and to install it.
I did not find tutos in Youtube, any help and advices would me much appreciated.
Google a little bit, you will find a lot of info on how to check if the firmware is double stack or if you need to install sip firmware. Once you get the sip firmware on the phone, you need to create a provisioning file and you can Google for that too.
Actually i’m not sure if i should transfer that file with TFTP, even i set the HTTP server accordingly into the phone ADDR menu.
I would appreciate advices / steps explaining how to upgrade the phone , i am also not confortable the config files to be pushed into the phone afterwards.
You can go with any SIP phone that you like, but if you want plug’n’play or if you don’t want to make any effort figuring things out by yourself, you better go with Sangoma phones, or any other phones that have a web page to set them up. If you wanna go with Avaya, just be careful which version you choose. 9620 are not supported anymore for SIP firmware. At least that can be seen with a quick Google search for avaya 9620 sip firmware.
