OpManager-8 VoIP Monitor help needed

OpManager-8 VoIP Monitor help needed

We have OpManager8 build 8052 and I have some questions regarding VoIP Monitor.
I setup some monitors (one through an MPLS network and another via IPSEC tunnel) that work fine but when I configure additional monitors configured the same way for additional MPLS and IPSEC tunnel sits they do not collect data. Whe I click on the "Troubleshoot" link I do see that the SNMP creds and source router are green and successful.
