The host offering the service

The host offering the service is the CUP server FQDN, just as you have it there

DearI didnt understood ??

Dear

I didnt understood ?? what are you trying to explain.

I have just shown in attachment 1 server configuration but actually i have 2 CUP servers so what will be the destination SRV in the trunk configuration.

You need to create two SRV

You need to create two SRV records. Point them to your two CUP servers. You can assign priority and weights to them to choose a preferred one or you can make the weights and priority the same for calls to be load balanced to both servers offering the service

Yes you can and should use

Yes you can and should use SRV actually. Ignore my previous post..You need to use the SRV cluster name in the destination field..ie (mjec.com)

You also need to configure DNS reverse lookup rules for both of your CUP servers

I dont see any confusion. the

I dont see any confusion. the destination address needs to be your domain. In that domain ensure you have SRV service configured. I dont what else to explain

In my previous post i was asking the destination SRV records of the links  what they have entered is different than the domain name, so i was asking you if you can elaborate more on the links.

CUCM will send a SRV DNS

CUCM will send a SRV DNS query to DNS for the device hosting the cup service. Your DNS will send a request with the names of the cup servers you have configured for the service.. This log sows a sample trace od how cucm obtains the cup servers hostname and ip address after sending DNS query
