J. Klein Posted February 4, 2021 Report Share Posted February 4, 2021 Hi everyone, Do I have to say more? Akuvox... Yah, the R26C with my T58a are not behaving. When the doorbell rings the T58 displays a black place holder for the video, but the video stream is not visible until the call is answered looking at the sip capture, the Akuvox video stream is there , its the t58 which is not displaying it at the ringing stage. Yealink has a new ROM 58.85.0.5 (up from 58.84) When upgrading, Kazoo will "downgrade it back to the older firmware. So, I deleted the 58 in Kazoo, did a factory reset, upgraded the firmware, and added the 58 as a SIP device on Kazoo NOT by selecting from the device list. then placed the sip credentials in the 58 and manually registered it. Just like I did with the Akuvox. I tested again and same results. Any ideas?! See video attached. T58a_Video_issue.mp4 Quote Link to comment Share on other sites More sharing options...
