How do I know which entry to use version 81 in provisioning.

Dear Sir,

Thank you for your detail info.

After checked the parameters you describe, it is correct for the phone.

Can you kindly provide the level 6 syslog, config.bin and pace trace when you do auto provision, so that we can locate the problem. Thank you.
About how to get the three files, please refer to the FAQ below:

Please also provide the directory .xml file to me.You can send it to Lucia@yealink.com.

Beside, please check for me if you use the parameter "directory_setting.url " to do provision, can it work well?

Thank you for your info in advanced.
