I updated one of our SNOM870 VOIP handsets to FW 8.7.5.35 and now cannot access the phone's administrative interface. The web access works and the phone finds the SIP proxy but many of the visible settings have changed such that the unit is no longer registered for the correct user. Further the communications SRTP settings of the unit are not compatible with the network.
The SNOM forums are closed to all but resellers. I have asked on the FreePBX forums but have had no useful response. So I would like direction as where else I can seek assistance.
