I have a VCS Expressway running in DMZ, and i am facing some issue with DNS SRV Records.
VCS Expressway Hostname:- VCSe
VCSE FQDN: VCSe.example.com
and i have a A Record configured for the same FQDN in Public DNS Server.
I have a sip domain configured as "cisco.com" in my VCS Expressway.
So what is the SRV Records i need to create in Public DNS Server.
It seems you haven't checked the link i sent you earlier.. Those documents a very self explanatory. Anyways the one we talked earlier is we were talking for signaling to send the calls to expressway as well as registration part.
In your deployment you have different domain for DNS and SIP domain. Also as you said you are having cluster of expressway and you want registration for endpoints as well then again i would suggest you to check the document for cluster creation on cisco webesite.
Now if you have a cluster for expressway then you need to create multiple srv records which would be pointing to each FQDN of cluster peer with equal weight. In a normal scneario use of common domain for different services are recommended.
The srv records would be seen someting like this.
_sips._tcp.company.com. 86400 IN SRV 1 1 5061 vcse1.company.com.
_sips._tcp.company.com. 86400 IN SRV 1 1 5061 vcse2.company.com.
_sip._tcp.company.com. 86400 IN SRV 1 1 5060 vcse1.company.com.
_sip._tcp.company.com. 86400 IN SRV 1 1 5060 vcse2.company.com.
_h323ls._udp.company.com. 86400 IN SRV 1 1 1719 vcse1.company.com.
_h323ls._udp.company.com. 86400 IN SRV 1 1 1719 vcse2.company.com.
_h323cs._tcp.company.com. 86400 IN SRV 1 1 1720 vcse1.company.com.
_h323cs._tcp.company.com. 86400 IN SRV 1 1 1720 vcse2.company.com.
_h323rs._udp.company.com. 86400 IN SRV 1 1 1719 vcse1.company.com.
_h323rs._udp.company.com. 86400 IN SRV 1 1 1719 vcse2.company.com.
However your case is different. In your deplyoment what you have to do is any request for the domain "cisco.com" should be resolved to FQDN of the VCS-Expressway peers with equal weight.
_tcp.gmail.com. IN SRV 20 0 5222 talk2.l.google.com.
so any request to gmail.com would resolve to talk2.1.google.com server.
same way you have to make it work.
