I use SPA962 with SPA932 and SPA942. I use the Server Type: RFC4235 on SPA932. Sip account is used on SPA942. IT works ok, SPA932 is correctly signalling the status, but there is a problem when i use DND on the SPA942 phone.
When I set DND at SPA942 on YES, SPA932 don't change the status of this line to BUSY. The SPA942 do not send any SIP information when i set on/off DND.
How can I set the config to watch DND mode on the phone ?
