For example i you have a SPA942 how you recommend i will configure the extensions for that phone
EX:

201 [LED1]
Line1[LED2]
Line2[LED3]
Line3[LED4]

I’ll recommend that all lines to use the same extension - but you have to ask your customer how the like to have.

I don’t use nor own this device. However, if this device can support four lines, then just register each line as an extension to your Asterisk PBX system. When each extension is called, then I believe the corresponding line on the device will be rung and its LED will lit up.
