[asterisk-users] Grandstream GXP2000 BLF

[Cary Fitch]

We have a system running SNOM 360s, and BLF works fine.

We are trying Grandstream GXP2000s and like the phones for what they are,
but can't get the BLF to work.

The IB just says to set to BLF and put in the phone number.  We have tried
variations like adding @xxx.xxx.yyy.zzz, but no lights light.

Does anyone have the "magic incantation" to get the BLF to work?
