I spent two weekends to try to make an old SPA2102-R working again, but this dumb thing is in Customization Pending mode, so it's locked for good :(

Luckily, I got a bunch of Cisco ATA190 that are unlocked, so I can use them instead ! #voip #telco #phone

After hours and hours to understand how they work and trying to find some information online, I finally figured out how to use an ATA190 with #FreePBX and #asterisk !

Basically, you need to send an XML file with TFTP. I will publish an article about it :D
