On a PBX I'd like to have a sensor tell me how many open RTP ports there are so I can see if some are stacking up or our traffic is going to overload the server. RTP ports span a set range of ports so I'd like to be able to get a count of how many of those ports are open at regular intervals.

The only existing sensor that could give you that are the SNMP Custom Sensor. Could be a bit advanced to set up.

I'm game for that. Any pointers on the advanced setup?

I'm not an expert on advanced SNMP. The user manual would be a good place to start.

If the vendor supplies a .mib file, you can use PRTG's MIB Importer to import MIB (Management Information Base) files and convert them into OID libraries for PRTG.

The SNMP sensor will be able to work with the converted OID.
