When test phone is on hold, there is no audio between it and phone B.Ĭompatibility with the Yealink T58V is the same as with all previous Yealink devices. When C picks up, audio must work in both ways between test phone and C. B must be released correctly after the transfer. An example of a test case would be the following:Ĭall must be transferred correctly to C. Compatibility TestingĪt OnSIP, we put each of the phones we use through a multi-step interoperability test in which we apply ~30 test cases. We spoke to a remote employee who uses video phones every day and he remarked that this is probably the best video quality he had seen from this office to his. When on a call, the video is smooth and avoids the tendency of looking excessively blocky when interoping with other manufacturers. The specs say that the phone performs at 720p (30fps), and we could clearly see that throughout our test calls. This is not quite eliminated from the current model, though the echo is not as pronounced on the Yealink T48G phone. We’ve never had an issue with Yealink phones, aside from complaints of echo in smaller rooms while using the speakerphone. Yealink CAM50 camera: Two megapixel, plug and play, adjustable, with privacy shutter and LED indicator.Video codecs: H.264 High Profile, H.264, VP8.Full-duplex hands-free speakerphone with AEC.DTMF: in-band, out-of-band (RFC 2833), and SIP INFO.Five-way video/audio mixed conferencing.Remote office, hot desking, intercom, paging.Anonymous call, anonymous call rejection.The Yealink T58V also boasts many other features, including: Most desk phones are used in conjunction with a full computer, so you’ll most likely be using whatever mail client you have available there. The feature seems "value added" rather than something from which you’ll get full functionality. The mail client worked, but we found it a bit clunky. Leveraging Android 5.1.1, the T58V gives you access to a calendar, a mail client, and a browser. If you want, you can record just your face during a video call by maximizing your own video, rather than the remote video, during the call. In a welcome twist, you can also record your video calls in addition to your audio calls. From what we can see, the V designation means that the detachable video camera comes included in the box. The T58 phone line is available in both "A" and "V" designations. The Yealink T58V supports up to 16 SIP accounts, built-in Bluetooth 4.0+, and 802.11 WiFi. Apparently some people have figured out how to sideload APKs, but we did not attempt to do so ourselves. Unlike Grandstream, Yealink doesn’t provide its own sanitized version, so you won’t be killing time with Candy Crush on conference calls. Although the phone is based on Android, there doesn’t appear to be a way to access the Google Play store. Our reviewer was not very familiar with Android devices, so the user interface took some manual reading to figure out how to access much of the “nonphone” functionality. ![]() Both the camera and the screen itself are individually adjustable (up to 50 degrees), so you can easily find a comfortable viewing angle for the device. The text and color displays are very sharp. The Yealink T58V has a 7-inch (1024 x 600) adjustable touchscreen-the nicest we've seen on a SIP device and probably why the phone is so expensive. The big attention grabber on the device is the screen. The spacing between buttons is also wider, so you’re less likely to incorrectly enter a number. Call handling features like transfer, do not disturb, and volume are on the left side of the phone, while the audio controls for headset, mute, and speakerphone are on the right. Yealink says that the new layout is more intuitive, and we can see that there was some thought put into where the buttons were placed. The design is very similar to the last line of phones, the Yealink T4x series, but with a different button layout. ![]() This device is ready, right out of the box, for serious business-grade voice and video calls.īut how does the Yealink T58V fare in an actual business setting? We conducted a comprehensive review to find out. The phone also has built-in Bluetooth 4.0+ for headsets and mobile devices. ![]() The T58V comes with a 7-inch 1024 x 600 touchscreen and support for up to 16 VoIP accounts. The phone boasts the best video communication and screen we have yet seen for a desk phone. The SIP-T58V is the newest high-end media phone from Yealink.
