I am working a FreePBX system that implements Cisco SPA 300 series and 500 series solely. I have been trying to find more information regarding programming the line buttons for special features, like call pickup, and the lower 4 programmable buttons, but I can't seem to find any proper documentation. Any help would be greatly appreciated.
Also if anyone has experience with provisioning these devices in a FreePBX environment I would love any and all pointers on that as well.
A Hopeful PBX admin
