Can anyone tell me if SIP services are usually a fee based service,
and/or if there are any reliable free services available?

The SIP services based on free and, or open standards mostly are
compatible; though this depends on an underlying implementation stack.
It is not mandatory for the ITSP, but most of these provide free PC to
PC calls for their registered users and, or even peers. However all
those calls which need to routed through PSTN Gateways are charged
legitimately, because they are required to pay for these to other telcos
who operate PSTN exchanges.
I have no experience with the quality, congestion and, or dependability
of any such services, but you may try the following yourself:

The granddaddy of free SIP calls, Jeff Pulver's Free Wold Dialup, is
still around, so is SIP Broker.

The inter "service provider" ties are still very scarce. Most of the
bigger VOIP services try to keep their customers from making direct
SIP calls to anyone but another of their customers. Some will have
access codes etc. to call customers of other service providers, others
will not. You might need to get a second SIP phone that isn't under
the control of a non-cooperating VOIP provider if you want to random
folks directly.
