Dear Kevin and all,

Thank you for a tip, it looks like I made a mistake in domain zone. I put whole subdomain record and it started to work.
Thanks again.

Best Regards

Temat: Re: Correct SRV configuration

The name "goyello.com" *itself* owns no SRV records. You never added any with that name.

"host" doesn't have any special knowledge of SRV records, and, besides, you didn't tell it what service and protocol, so it didn't even have enough information to construct the appropriate name to look up.

You have to treat the names of SRV records like any other DNS names, and spell them out completely. Look up _sip._tls.goyello.com and _sipfederationtls._tcp.goyello.com and you should find the relevant SRV records in the appropriate places.

Example lookups can be found at http://en.wikipedia.org/wiki/SRV_record

                                                                                                                                                                    - Kevin

P.S. 9.2.4 is really old. Upgrade.

Dear all,

I have named 9.2.4 . Everything is working fine. Unfortunately yesterday I faced issue with setting up SRV record.
Below is how I tried to configure it for MS Lync service:
_sip._tls        3600    IN    SRV    100 1 443 sipdir.online.lync.com.
_sipfederationtls._tcp    3600    IN    SRV    100 1 5061 sipfed.online.lync.com.
Everything looks like it is described in RFC2782:

Here is the format of the SRV RR, whose DNS type code is 33:
_Service._Proto.Name TTL Class SRV Priority Weight Port Target

The point is, that when I ask domain for SRV  record I receive:
$ host -t SRV goyello.com
goyello.com has no SRV record

Does anybody know where I made a mistake?
Thank you in advance for a help and tips.

Best Regards
