So, I don't know if anyone else has had the joy of trying to set up a Snom M700 and pair a Snom M65 handset with it. The 3CX how-to's are horrible, lead you into dead ends only to find out the solution (which isn't mentioned in their how-to) is far off in a distant world living in some SNOM wiki page.... After almost 5 hours, I managed to bring my Snom M700 up to date with the latest firmware ("Important note 3 at http://wiki.snom.com/Snom_M700/Firmware, a 3CX support tech told me to look at (which mysteriously isn't mentioned on their "upgrade firmware" page for the Snom M700) ---- so that when I do follow 3CX's how to (https://www.3cx.com/sip-phones/snom-m300-m700-dect/) , at least the images match, so I can get *almost* through step one. Worse, they interchange the word "base" and "phone" so much I never know what they're talking about! Then I get to the part that is supposed to show how to "register a Handset to a Snom M700 Base Station": https://www.3cx.com/sip-phones/register-handset-snom-m700/ Open the web interface of your snom M700 base station. Navigate to “Extensions” If this is the first handset you are registering, check the “Idx 1” tick box and click “Register Handset(s)” ..... WAIT 3CX! If this is the first handset I am registering, THERE IS NO IDX 1 CHECKBOX OR ROW OR ANYTHING IN THERE.... which means.... "REGISTER HANDSET(S)" DOES NOT EVEN SHOW UP. 1.5 hours to set up entire phone system, upgrade firmware on yealink phones, configure extensions, ring groups, SIP trunks, Inbound/Outbound rules........ SIX HOURS TO [attempt to, still going....] GET A WIRELESS HANDSET TO WORK.
