Thanks for your information and glad to here that this issue 2 was fix.
For issue 1, please kindly send PCAP,syslog,config,bin files soon.

For question 2 with this method 'account.1.sip_server_mode = ', the default value is 0.
If we set this value is 0, then the phone will make A record query in IPV4 environment.
If we set this value is 1, then the phone will make A record query in IPV6 environment.

Now our global customer is using IPV4 environment. Anyway, i will add this case into our FAQ, then it can help our customer.


Files sent now for question 1.

For question 2, can you request to developers as a feature request there be a value of 2 created which does an autodetect and can work with both types of address? It seems odd to me to have a default settings which does not work with both IPv4 and IPv6 and actually forces IPv4 SIP only.
Many other applications work with dual-stack or single stack environments by default so it would be good if Yealink phones can be the same.


Dear Reuben

I'm sorry we can't do more troubleshooting without syslog(level 6) and PCAP files.

After set the IPV6 configuration, the phone will reboot. After reboot, please go to settings->configuration to enable syslog level as 6 and start PCAP feature, you can push the phone to register.

Then you can reproduce the issue and export all files to me.

Thanks for your help.
