Search softphone

Hi all, I’m search a softphone to make video calls in Iax2. I prefer se free. Ekiga use sip and Zoiper is charges only. You have solutions?

An Internet search turned up the following: Comparison_of_VoIP_software

It appears that the Ring softphone handles both IAX2 and video. I’ve never used it and it appears that it is still in beta, but may be worth trying.
