softphone app for mac alternatives

[iris_failsafe]

So the cable company sold my mom VoiP phone service, she has a Mac (QS g4) and she asked is this program compatible with mac, they assure her that yes, of course when they went to install it it was Windows only, the problem is that she is already subscribe for the service so is there a compatible programme for mac instead of softphone

Thanks

Which cable company, don't they usually provide an ethernet to POTS hardware solution rather than a PC client?
