For question 2, you need to use AutoP to provision this phone.
For question 1, waiting for all the files.

To follow this issue better, i hope you can send e-mail to me Kevin@yealink.com.
It would be better if you can share me more inoformation about yout test plan. Is there a new projects?

Hi Kevin,

Question 2 is resolved - by adding account.1.sip_server_mode = 1 . After adding this I was able to register with an IPv6 only hostname for my SIP server.

This setting doesn't seem to be documented anywhere. Can this be added to the documentation so the next person who runs into this problem can find it?

Also why is it that the IPv6 DNS lookups are disabled by default? This seems to be a little odd, I think it would make more sense to request DNS lookups over IPv6 first if IPv6 is configured on the device, rather than completely disable the IPv6 resolvers entirely.

Thanks,
Reuben

Hi Reuben

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.

BR
