T32G - Slow Directory Response Times?

[Heisenberg]

Hello,

We are currently in the process of trialing a VoIP system using a couple of Yealink phones, T32G and T46G.

The T32G seems to be quite slow when responding when navigating within the directory (tested with both LDAP and local directory), whereas the T46G responds pretty much instantly. Obviously I expected a slight difference between the two, but the lag on the T32G is noticeable and rather annoying.

This seems to be the only feature of the phone that runs like this, otherwise it is pretty responsive.

Is this a known issue and/or are there any known workarounds?

Worth noting the phone is on the latest firmware.

Thanks!
