The default firmware is based on some fairly old code because T46S has a number of bugs fixed that are still present in T46U default firmware. Not much help, I know.

We bought a batch T46U by mistake because reseller marketed them as T46S replacement, which is not really correct. We ran into some bugs in the default firmware. I opened a ticket and got a sensible response and support provided a firmware image that resolved our problems, but unfortunately until the firmware is officially published I can't tell the call centre to use it. So we are not buying any T4?U until this phantom model line appears on the support pages and we can re-evaluate our options. T54W seems like much better option than T46U IMO, and where we are only $20AUD more. If Bluetooth or WiFi is required then the cost of the adapter for T46U will offset that price difference.

I agree smuser. T46S is very similar. Our provider suggested using the T4xS templates for configuration.

Just odd that these new phones are out but no Yealink centric resources to get data sheets, firmware, config info, etc.

T54W is more expensive in US as well and we may end up just using that model instead of the 46U.

Agree also on the wifi and bluetooth being built in --- can be handy for clients that need that and will offset the cost. The one option missing on the T54W is the expansion module port which the T46U does have.

What features do you use on the 46U that are buggy? We have only put one in so far with no issues.
