I'm experiencing difficulty upgrading the m300 basestations as well as the added m25 phones on m325 packs.
I'm following this wiki: http://wiki.snom.com/FAQ/snom_M/update_using_dect_snom_com
Using an example instance, I entered the following in
Address of Firmware Server: http://dect.snom.com
Firmware Directory: <empty>
I left the m25 fields blank for now as I want to upgrade the base stations first.
Required Version: 324
I currently have
Now if I click ok, pretty much nothing happens - the box reboots, which takes only seconds, then its still the old Firmware Version.
If I do the same for 355, the box blinks orange for about 13 minutes and then reboots, however the old Firmware is still installed.
We tried the upgrade with "324", "0324", "0324" Branch "12", also with Branch "0012", but nothing seems to happen to the handset (even after some minutes). The syslog says:
loc3 .Info 2017-03-15T19:13:12Z 173-[ VoIP Number of configurations parsed: 6]
loc3 .Info 2017-03-15T19:13:12Z 173-[ DECT Number of configurations parsed: 0]
but no action seems to be taken on the m25 handset. We made sure the handset was in the loading station at all time and was not doing any calls or such. We restarted the handset and the basestation also once or twice, with no effect.
You should be able to upgrade headsets from any firmware version to latest 355B21 (We recently released B22)
Please configure as shown
I recommend you also to enable syslog to DEBUG mode to see http request. Maybe you are getting any error when downloading headset firmware.
