In order to monitor VoIP between two locations, you need to specify the links that you want to monitor using OpManager, that is, specify the source and target. The source router (Cisco router with IP SLA agent enabled) must be discovered in OpManager first. Only if this router is discovered in OpManager with valid SNMP read and write community strings configured, you will see the router listed as a source device and you will be able to pick so that you can successfully add a VoIP monitor.
