Dears,
I have CUP publisher and subscriber.
I have created a sip trunk in our CUCM 8.6.2. In the section SIP Informaiton, there is a destination box. 1* is required ip address and port. To the right of this is a + button, that adds a new destination address and port destination. How is this second one used? Is it a round robin, or is it use 1* till 1* fails, then fail over to 2?
When we should use SRV records.I hope in a multinade but for my scenario how i can make a use of this feature.
In Jabber client login server address what ip address i shld put so that incase of failure of any server the jabber client should't put the redundant server ip address again to login, the failover should occur transparently without any changes on the jabber client
Thanks

Well, you did not create an SRV to point to SIP port 5060 of the CUPS servers. Build something like:
CUPS to CUCM
_sip._tcp.CUPS.abc.com SRV service location:
priority = 10
weight = 0
port = 5060
svr hostname = vCUPSub1.abc.com
_sip._tcp.CUPS.abc.com SRV service location:
priority = 10
weight = 0
port = 5060
svr hostname = vCUPSPub.abc.com
and then use CUPS.abc.com as the destination of the SIP trunk.

DNS SRV for CUPS/IM&P HA has been discussed plenty of times before

It is top down, if you want load balancing for IMP use SRV.

I am little bit confuse, I have created below configuaration in the DNS server, now i want to know what is should feed in the destination address of the sip trunk.
What will be my SRV destination address ???. according to the below configuartion.
_cuplogin._tcp.abc.com SRV service location:
priority = 0
weight = 0
port = 8443
svr hostname = cups-sub.abc.com
_cuplogin._tcp.abc.com SRV service location:
priority = 0
weight = 0
port = 8443
svr hostname = cups-pub. abc.com
CUPS to CUCM
_sip._tcp.CUCM.abc.com SRV service location:
priority = 10
weight = 0
port = 5060
svr hostname = vCUCMPub1.abc.com
_sip._tcp.CUCM.abc.com SRV service location:
priority = 10
weight = 0

svr hostname = vCUCMSub1.abc.com

Hello Chris,
Thank for the reply.
CUPS to CUCM
_sip._tcp.CUPS.abc.com SRV service location:
priority = 10
weight = 0
port = 5060
svr hostname = vCUPSub1.abc.com -----> i think this should be replaced by svr hostname = cups-sub.abc.com
_sip._tcp.CUPS.abc.com SRV service location:
priority = 10
weight = 0
port = 5060
svr hostname = vCUPSPub.abc.com----->i think hostname should be replaced by svr hostname = cups-pub.abc.com
CUPS to CUCM
_sip._tcp.CUCM.abc.com SRV service location:
priority = 10
weight = 0
port = 5060
svr hostname = vCUCMPub1.abc.com
_sip._tcp.CUCM.abc.com SRV service location:
priority = 10
weight = 0
port = 5060
svr hostname = vCUCMSub1.abc.com

I did not know you hostnames so I left it up to you.
_cuplogin is used by Jabber clients as that is the default connection they will use.

Dear Chris,

You dont need to add _cuplogin anywhere, that is built into Jabber client and will be used natively unless you change the CUPS destiantion in jabber-config.xml.

Hello
I am using Jabber 9.2 and the issue what i am facing is same according to the link below,
Does anyone even know where this value is stored so I can remove it?
11-01-2013 01:00 PM
The config is stored in jabber-config.xml file which Jabber downloads from TFTP (CUCM server), if you have not modified the file then it should just point to your _cuplogin srv assuming you select on prem CUPS not webex Connect.
Can you resolve the srv with nslookup?

Hello chris,
I was just checking jabber.config.xml file on TFTP of call manager, I did'nt found this file, I was surprise so i went to see in my previous client presence server installation i checked in CUCM i didnt find any jabber-config.xml file but the jabber is working fine for that client.
I think the jabber-config.xml is uploaded in TFTP only when customized jabber is required please confirm ???
Thanks

If it is not there that means the default is used which means reliance on _cuplogin srv or statically entering server during loign.

Hello,
For previous client there was only one server so i was using the ip address but now in this case i have a redundant server so i am using SRV records and also I am selecting CUPS and not webex,still on pressing the default button the value comming is https://loginp.webexconnect.com/cas/auth.do . It is irritating and i dont know from where to remove the link.
Thanks
