Hello Bala,

The only other way i can think of is sending the call to the DNS Server where it can resolve to multiple IP address using a DNS SRV file. Below is the section from CVP SRND which explains your scenario.

"When a call arrives at an Ingress Gateway, the dial peer can use DNS to alternate calls between the

two SIP Proxy Servers. The SIP Proxy Servers can also use DNS to distribute incoming calls among

multiple SIP Services. If SIP Proxy Servers are not being used, then the Ingress Gateway can use

DNS directly to distribute inbound calls among multiple SIP Services"

You can achieve this using the dial-peer Session Target.

dial-peer voice 75795 voip

      session target dns:cvp.callserver.com

Have a look at the below blog which explains the SIP Proxy Reduncancy, but it can also be done for CVP
