4 phones Yealink t48g Firmware Version 35.80.0.70 + FreePBX 13.0.49 , Asterisk Version: 13.5.0 + BLF
I've set up 4 t48g phones on my local network and remote network (2 Server : local server for testing, remote server is live ) . Everything seem to work fine . I can dial out, receive call, transfer .. call just fine . The only problem I have right now is BLF does not work at all .
All 4 phones
Phone 1: Extension 500, BLF:501,502,503
Phone 2: Extension 501, BLF:501,502,503
phone 3: Extension 502, BLF:501,502,503
phone 4: Extension 503, BLF:501,502,503
all the BLF keys registed and stay green
when I press on these BLF key , phone will dial extention but none of the phone BLF key change the status . They all stay green.
After spending 1 full day on google and on this forum . Here is what I did
I went into each phone webpage and make sure: Account -> Advanced -> SIP Server Type = Default
On Freepbx:
Settings->Advanced Settings->Display Readonly Settings + Override Readonly Settings = YES
Dynamically Generate Hints = YES
Reboot phones and servers . Everything seem to work find but BLF still does not work . Please help
