I have recently updated to the latest 3cx PBX version 15 with SP5 and all the updates, I have Snom 760 and Yealink 41/42 handsets, yealink phones work fine. I have noticed an issue with firmware version snom760 18.104.22.168 it keeps rebooting the handset every few minutes for no reason i have the same result on all the snom 760 handsets i have tested this on. I have spoken 3cx support whom are telling me to contact snom with syslogs etc however i only have this rebooting issue with firmware of 22.214.171.124 on snom 760 handsets. Anyone else with Snom 760 and 126.96.36.199 firmware working fine for them???
