RE: Protocol specification with DNS SRV
Hi Evan,

We are having same issue. See our dns srv config in dns server.

_sips._tcp.sip 20 10 5061 sip2.demo.com 180 Domain
_sips._tcp.sip 10 10 5061 sip1.demo.com 180 Domain
_sip._tcp.sip 10 10 5060 sip1.demo.com 180 Domain
_sip._tcp.sip 20 10 5060 sip2.demo.com 180 Domain
_sip._udp.sip 10 10 5060 sip1.demo.com 180 Domain
_sip._udp.sip 20 10 5060 sip2.demo.com 180 Domain

so in grandstream if set transport to udp it always query for below entries
_sip._udp.sip 10 10 5060 sip1.demo.com 180 Domain
_sip._udp.sip 20 10 5060 sip2.demo.com 180 Domain

so in grandstream if set transport to TCP it always query for below entries
_sip._tcp.sip 10 10 5060 sip1.demo.com 180 Domain
_sip._tcp.sip 20 10 5060 sip2.demo.com 180 Domain

so in grandstream if set transport to TLS it always query for below entries
_sips._tcp.sip 20 10 5061 sip2.demo.com 180 Domain
_sips._tcp.sip 10 10 5061 sip1.demo.com 180 Domain

Which gives us much better control and it is simple as well. We are trying to find similar way in yealink but unfortunately if we set port to 0 and transport to dns-srv phone only looks for UDP entries. Can you give us better way to do this procedure?

Thanks,
Muhammad Yousuf

This is Evan from Yealink Support Team, nice to know you!

For your question, please set the port of SIP server as 0, and try again.


If not help, please reproduce it and offer us the diagnosis files(level 6 local log / pcap / config.bin). Below is the FAQ about how to get the files:

Please let me know if anything I could help.

Best Regards,
Evan You
