2 thoughts on - Yealink T26 And T28 Panels

• Hi!
  I frequently use the newer T48G and T46G phones with the EXP40 expansion module. There are issues, if you are logged into the phone via the webinterface as an admin. Among other things, the display is not properly updated and wrong numbers may get dialed. Some time ago, there was a firmware update and I am not aware of any stability issues at the moment.

  How do you supply power? 3 expansion modules + the phone and a cheap POE switch could be critical. It may not be the power itself, but the correct handling of energy saving states.

• Originally we used just POE but now each of the 3 panels has its own PSU

  Hi!

  We have a strange a strange issue at a client they have 3 panels on their phone and every so often the panels reboot themselves yet the phone stays on.

  We decided to replace the T26 for a T28 to see if it fixes the issue and still have the exact same issue.

  Has anyone seen this before?
