FusionPBX Custom Configs (134.209.72.226)

Yealink T48S Provisioning — Critical Fixes

Problem: BLF buttons never applied from provisioning

Root cause: nginx rewrite for {mac}.boot stripped the file= param, so FusionPBX served the full 122KB config as a boot file. Yealink ignores DSS keys in .boot files — they only apply from .cfg files.

Fix 1: nginx rewrite (in /etc/nginx/sites-enabled/fusionpbx)

OLD: rewrite "^./provision/([A-Fa-f0-9]{12})(.boot)$" /app/provision/index.php?mac=$1; NEW: rewrite "^./provision/([A-Fa-f0-9]{12})(.boot)$" /app/provision/index.php?mac=$1&file=%7b%24mac%7d.boot;

Fix 2: {$mac}.boot template

Created: /var/www/fusionpbx/resources/templates/provision/yealink/t48s/{$mac}.boot Content: boot file with includes pointing to y000000000065.cfg and {$mac}.cfg Phone flow: {mac}.boot (164 bytes) → y000000000065.cfg → {mac}.cfg (full config applied)

Fix 3: y000000000065.cfg template changes

features.auto_linekeys.enable = 0 (prevents phone overriding BLF keys)

Fix 4: All y000000000000.boot templates

overwrite_mode = 1 (forces re-provision on every reboot, default was 0)

Fix 5: External sofia profile

manage-presence = passive (not true — BLF SUBSCRIBEs delegate to internal profile)
Fix: UPDATE v_sip_profile_settings SET value='passive' WHERE profile=external AND name='manage-presence'
Then delete /var/cache/fusionpbx/FusionPBX.configuration.sofia.conf and reload sofia

Park buttons use Speed Dial (type=13) not BLF — BLF for park requires mod_presence which is not installed. Speed Dial works: press during call parks it, press idle retrieves.

mod_presence

NOT installed — FreeSWITCH built from source at /usr/src/freeswitch-1.11/
Basic extension BLF works via manage-presence=true on internal sofia profile
Park slot BLF would require mod_presence — workaround: Speed Dial buttons
