Problem Change Firmware T48s from SFB to SIP - Lars Maschke - 11-18-2021 08:01 PM Dear Community, I tried the new firmware 66.9.0.100 for "Skype for Business" on T48s. This was just for trying SFB. I can't reset the phone to the normal SIP-Version firmware 66.86.0.15. This does not work. There is still the SFB-version installed. How can I change this behavior? Thanks in advance Lars RE: Problem Change Firmware T48s from SFB to SIP - jeff.smith@singlesrc.com - 01-10-2022 08:04 AM (11-18-2021 08:01 PM)Lars Maschke Wrote: Dear Community, Did you ever figure anything out?
