Dear Experts,

Having issue with SIP HA, if Secondary becomes Primary agent can not hear any voice .

what are the field to be checked

[genesysguru]

What SIP HA method are you using and is this on Windows or Linux. Check you HA scripts are working and the VIP interface up/down is OK. Also ensure that everything is configured to use the SIP VIP address where relevant. After that it is a case of understanding the SIP signalling and following the RTP streams.

Is your RM or MCP running on same server as the Genesys SIP server?

Yes , RM/MCP and SIP running on same machine

As I know, Windows NLB has a limitation, where the cluster IP address:port is not accessible from cluster node which is stopped/non-active at this moment
