How to create an SRV record for the CSTA service

King, Harold Clyde (Hal)
I'm kinda stuck. I am tasked with creating an SRV record for the CSTA service. But I must be doing it wrong.

Here's what I thought it should be:
_csta_tcp.csta-example.com. 3600 IN SRV hostname.example.com.

Am I even close?

There's a typo in my record. It's _csta._tcp.csta-example.com. 3600 IN SRV hostname.example.com.

You have me dead to rights on that. I was trying to make an example and failed. Here's my record:
_csta._tcp.csta.example.com.   3600   IN   SRV   20   0   1040 hostname.example.com

The SRV record needs 4 data items; you've specified only one.

For an easy read: https://en.wikipedia.org/wiki/SRV_record

For something more formal: https://tools.ietf.org/html/rfc2782

Good luck!

Instead of "hostname.example.com", you need "hostname.example.com.", with a trailing dot.

OK I made mistakes. I’m sorry for wasting anyone's time, I really am.

I was trying to see if anyone had even made an SRV record for the CSTA service. My presentation of the dig example was a poor choice.

Re: How to create an SRV record for the CSTA service

Darcy Kevin (FCA)
CSTA? Are you talking about the Unify Openscape Voice stuff? If so, then that's a VoIP platform, the SRV records are used for SIP stuff. So the service name is "sip" or "sips". You can't just make up service names, out of thin air, for "dumb" devices that have service names baked into their code -- you have to publish records with a service name that they are going to be able to find.

Our SRV records for Openscape Voice look like, basically, 

_sips._tcp.{sip-domain}. 3600 IN SRV 10 0 5061 {target}

and/or 

_sip._udp.{sip-domain}. 3600 IN SRV 5 0 5060 {target}

I'm simplifying a bit here. Each of them has a primary (pref 5) and a failover (pref 10). 

sip                5060        tcp    SIP                                                                                                                                                       2014-04-09   [RFC3263]
sip                5060        udp    SIP                                                                                                                                                       2014-04-09   [RFC3263]
sip                5060       sctp    SIP                                                                                                                                                                    [RFC4168]
sips               5061        tcp    SIP-TLS                                                                                                                                                   2014-04-09   [RFC3263]
sips               5061        udp    SIP-TLS                                                                                                                                                   2014-04-09   [RFC3263]
sips               5061       sctp    SIP-TLS 
Talk to your Voice folks for the values to plug in for {sip-domain} and {target}, in each case.

Meh.  Don’t sweat it .. everyone has goofed in some manner at sometime or another.

Besides, we are team BIND!  We won't tell a-n-y-o-n-e.
