Cpanel is a bit tricky when adding SRV records because when you add the domain name to the name part, within WHM, during saving it actually removes it which is confusing.
Name | TTL | Priority | Weight | Port | Target |
_sip._tls.domain.com. | 10 | 10 | 1 | 443 | sipdir.online.lync.com |
_sipfederationtls._tcp.domain.com | 10 | 10 | 1 | 5061 | sipfed.online.lync.com |
So in WHM make sure you add them in the format below.
NOTE: When you save the dns record and go back to it, the domain. part will be taken out but if you do a SRV check you will see they will be working just fine.
