2600Hz Employees Isaac Posted May 6, 2016 2600Hz Employees Report Posted May 6, 2016 Hi everyone, In an effort to improve the performance of call pickup on certain Yealink models, we've identified that Yealink phones provisioned with our new provisioner are using firmware too old to support our "fast-pickup" feature (which reduces the amount of time it takes to pickup a call that has been parked to roughly under one second). The older firmware doesn't do this, so picking up parked calls takes many seconds when it could be much faster. After much research and testing we've narrowed down the cause to a specific issue in Yealink's firmware on T22, T26 and T28 model phones and T4x series phones running firmware version x.72.0.xx to x.73.0.50 or x.80.0.95.We've done some initial testing with a few customers and in our lab and the new firmware appears to work well and doesn't break any other features. Thus, we're scheduling a maintenance for tomorrow night, May 6th, 2016 after 5pm Pacific, to roll out the new firmware to Yealink phones. Yealink phones will typically pick up this firmware update within 24 hours. The specific models affected are the following: T22, T26 and T28 from x.72.0.80 to x.73.0.50 T4x series from x.72.0.xx to x.80.0.95 This update should be transparent to most users, but if you have any issues with it, please let us know.
FASTDEVICE Posted May 6, 2016 Report Posted May 6, 2016 Thanks for sharing Issac. The Yealink support site shows the most current firmware for the T28P is x.73.0.50. Is the firmware you are referencing even new than that? If so, will it be posted to their site or somewhere else for manual upgrade?
2600Hz Employees Isaac Posted May 6, 2016 Author 2600Hz Employees Report Posted May 6, 2016 @FASTDEVICE. The version we are upgrading to is x.73.0.50 for the T28.
