Hi Kevin,
I will get back to you later with the information for question 1.
For question 2, these phones are semi-live, currently testing them in my home environment so I am able to make changes and test things out quite easily.
I have only configured these phones via the web interface so far but I will be provisioning by config file at a later date. Does this sip_server_mode option appear in the web interface at all?
Thanks,
Reuben

This is Kevin from Yealink support team, nice to know you.
For question 1, we need your help to export syslog,config.bin,pcap files to me. You can refer to the FAQ to get those files.

NOTE: I need your help to export those files in 2 scenario(global address and link address for gateway), then i can do a comparison.
For question 2, please kindly help use this parameter 'account.X.sip_server_mode=1' to provision your phone. Please change X to corresponding line. Default value is 0, so it will not DNS on IPV6 environment.
If the issue still exist, please kindly send files to me.
May i know how many phones in your side now? Is there new projects so you are testing yealink phones? Can you share me more information about it.
BR
Kevin
