Very sorry. They are leaving for anual trip these days and will back on next Monday.
I just check in a T41 with V73 firmware. It seems that phone send a correct capability. Not quite sure whether it's an issue in firmware 36.71.19.6.

.... .1.. .... .... = 100BASE-TX (full duplex mode): Capable
.... 1... .... .... = 100BASE-TX (half duplex mode): Capable
...0 .... .... .... = 100BASE-T4: Not capable
..1. .... .... .... = 10BASE-T (full duplex mode): Capable
.1.. .... .... .... = 10BASE-T (half duplex mode): Capable
0... .... .... .... = Other or unknown: Not capable

May I know who direclty sell phone to you? Maybe you can also contact them for an instant support. Our guys will check the issue in Monday.

Regards,
James

Tadiran Telecom sells to us directly.

Here is the output of the switch "sh lldp neighbors detail" It shows the phone Speed/duplex: 100baseTXHD. I have contacted Tadiran and they say it is a Yealink issue. Yealink generates the software for them. How is the phone performance being impacted by operating at half duplex?

Please have someone test the version I am using. 5/5/15

Thank you Mike

So is this a firmware issue? If it is, can Yealink please inform Tadiran Telecom of it so they can get updated firmware? I still have no resolution to the my issue. Mike Schrader 5/17/2015 7:06 pm PST

Yealink has confirmed that this is a bug in all T4x Tadiran branded firmware. A correction will come in the next firmware version. Mike Schrader 5/21/2015 5:51 am PST
