IAX2 Open Source Client

Greetings,

I am working on a project using IAX instead of SIP.

I need to find an open source IAX2 client that supports video calls for use on a Debian based system. I seem to only be able to find closed source (Zoiper) or open source that does not support video (SFLphone)

If anyone could point me in a useful direction, I would appreciate it.
