EHS36 with Plantronics Savi720 on T38G

[Yealink Support]

Hi Stefan,
Please try to upgrade EHS36 firmware with below firmware on T38:
ftp://yealinkftp:yealinkftp@ftp.yealink.....0.162.rom

How to upgrade EHS36:

1.Upgrade T38G to the firmware 38.70.0.162:

ftp://yealinkftp:yealinkftp@ftp.yealink.....0.162.rom

2.Set a DSS key as Zero-sp-Touch

3.Press DSS key, it will prompt “Update Expand”, then press OK button, and it will prompt "Please insert expansion!"

4.Connect EHS36 to T38G, then it will ask connect it again.

5.And it will wait some time(please wait patiently, during this, please don’t reconnect it again.)

6.When upgrade finished, it will display "Update Success!"

If the problem is still, i am afraid we need logs to analyze the problem, and we just tested with Plantronics Savi 740, but didn't test with Savi 720, so we are not sure whether it works or not.
Could you provide PCAP trace, syslog(level 6) and config.bin these three file to us, so we can analyze?
Before you export the syslog, please set log level as 6, and reboot the phone, then click Start,and reproduce the issue, then click Stop,and export the trace, syslog, config,bin to us.
These three files are very important for us, hope you can kindly understand.
Thanks.
