Either the secondary DNS server's zone file/database doesn't have the required records or the client lacks the secondary DNS server in it's network configuration. When validating the DNS records, ensure both the SRV and A records they resolve to are working.

Jonathan,

Thanks for your response,

We entered the secondary DNS information on call manager and IM presnece Server. you mean to say in config file i need to add the records?

No. The user's PC/laptop/mobile device needs to know about the secondary DNS server. Try doing a forward and reverse lookup for all of the records on the secondary server. Either the client doesn't know about the second DNS server or a record is missing.

Do i need to enter manually SRV for Secondary server?

I Verified the SRV record by DNS query , it resolving secondary. What is the next step of troubleshooting i can perform?
