I have had the same issue on 2 new FreePBX installs with Commercial Endpoint Manager installed.
Phones provision happily EXCEPT the BLF side of things.
I create BLFs to monitor extensions and do call parking and set all to account 1
What happens though is the account numbers on the phone handset increment.
On DSS key page of yealink, Line one get account N/A, Line 2 gets account 1, Line 3 get account 3 and so on.
Anyone else come across this?
Both are new installs of FreePBX within the last month.
Using latest firmware on phones provided by EPM and latest distro.
All system and module updates are done.
I’ve had issues with the phones coming with newer firmware and it essentially downgrading when grabbing the config from Endpoint Manager. This caused some of the Yealinks (T41S and T46S) to have a similar issue. The fix was to factory reset the phone and when it pulled the config, it was fine.
In my instance, they came with v82 and downgraded to v81. And FYI, anything higher than 81 has some BLF issues, due to a forced standard adherence
I guess if there is a buggy firmware version then i would have thought that EPM would not allow you to upgrade to it or would give you the lower version that works as most recent …
