Hello,
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.
Regards,
