Command line (non-gui) softphone?

Hi all,

Are there any command-line based softphone out there that can interact with the Asterisk server? I’ve tried Xten, SJphone, IaxLite, and Idefisk. But they are all GUI based. I wanted to install a softphone in my Asterisk server, but my linux machine is a server edition (non-desktop with no X windows). I couldn’t use any of these GUI-based softphone here?!?!

Thanks in advance!
