Simple Phone Dialer for Win10

I have an Ooma telephone system and a LSI Network-LSI PCI-SV92EX Soft Modem in a PCI/E slot on my Dell XE2 I5 Desktop with 32GB of memory running Windows 10.  I want to be able to use that modem and the microphone in my Logitech webcam to place and receive phone calls.  Can I do that with this modem?  (Some modems I believe are just for faxing.)  Given that I can use this modem to make VOIP calls through Ooma, could you recommend some easy to use dialing software.
Thanks,
Al
