We’re running FreePBX 220.127.116.11 and have a mixed network of Yealink T48G and Sangoma handsets. Two of our Yealink phones no longer ring when calls come in; they go straight to “missed call” while the other handsets in the office are ringing. My sysadmin tells me that those two extensions show as busy before taking off for vacation. I have confirmed that DND is not on for either extension (by dialing *79 from both affected handsets.)
I’m a competent UNIX developer but not particularly savvy about Asterisk or FreePBX. How can I troubleshoot what’s going on?
