Switchvox - How to place contacts on Sangoma Phone's Line Keys

Sangoma phone models D50 and D70 feature a Busy Lamp Field (BLF) sidecar that can be used for speed-dialing contacts configured in the Switchvox or Asterisk system. For added contacts space, these BLF contacts can be moved to begin at the unused Line Keys next to the phone's main display.

These instructions assume that the Sangoma phone is configured via DPMA and has a configured contacts list. Instructions for configuring a contacts list can be found here: https://sangomakb.atlassian.net/wiki/spaces/Phones/pages/21037279

To enable contacts listing on unused line keys, do the following:

1. In the phone's configuration section in res_digium_phone.conf, add the following line: blf_unused_linekeys = yes

2. Reload the Sangoma Phones for Asterisk Module in Asterisk: module reload res_digium_phone.so

3. Reconfigure the phone, either from the phone's interface or from Asterisk using DPMA: digium_phones reconfigure phone <phone name>

When the phone reconfigures, the contact list entries will appear on the unused line keys on the phone's main display.
