Finally got Gizmo to work properly
I finally got Gizmo to work properly, that is, make outgoing phone calls from Gizmo.
In the past few months, the GNU/Linux Gizmo client kinda crapped out—I could receive incoming calls, but couldn’t make a successful outgoing call or do anything on the dialpad (in or out). It probably has to do with some protocol change—the GNU/Linux version hasn’t been updated since 2007.
So, I tried installing the Windows version under Wine, and it looks like it’s working better than the outdated GNU/Linux version, so I guess I’ll use this from now on (or at least until the Gizmo credit I have runs out).
P.S. I also got ALSA properly set up on my system with software mixing. Now I don’t have to periodically kill Firefox to kill its child Flash processes which are hogging the sound card.
