How can I do a factory reset of the EXP40? I recently upgraded my T46G from firmware version 28.71.0.105 to version 28.71.0.108 and performed a factory reset of the T46G.
However, after doing the reset, some of the BLF lights on the EXT40 were still lit, while some were completely out (even though all keys were cleared in the web interface and all keys on the LCD were blank). After re-entering all of the DSS keys on the EXT40 (I have all 40 keys on the EXP40 set to BLFs), some of them show correct BLF status while others don't. Some will continuously show red (whether the extension is in use or not), some will continuously show green (again, whether the extension is in use or not), and others will not show any status at all (the light will be out completely). What's even more perplexing is that some BLFs will work just fine, showing correct status.
I've reset to factory defaults on the T46G twice and see the same issue. Between the two resets, different BLFs worked/didn't work, so I wouldn't imagine it's has anything to do with the specific extensions being monitored by the BLFs. Moreover, non-Yealink phones are monitoring the same BLFs without issue. Perhaps there is some incompatibility between the new firmware for the T46G (28.71.0.108) and the existing firmware for the EXP40 (6.16.0.0)?
Is there something which needs to be done to reset the EXP40 to factory defaults other than resetting the T46G to factory defaults?
