Yes.

Add your health check as a normal resource.

Stop. That sounds like a monitoring task of a resource. You have to add this 
checks to the monitoring part of the SIP Proxy and / or openHA.

Basically:
Health checks are for testing the health or a cluster node, i.e. CPU load, 
free space on a partition or something like that.
If you want to check a resource (application) then you have to improve the 
monitoring function of the according Resource Agent.
