Are there any H323 clients that are stable (don't crash all the time)?
I only found Ekiga, but people in my work group are telling me that it is unusable, because it is crashing all the time.
Is there a stable client? Can be commercial.

There are quite a few:
Vimprobable - WebKit and Vim-like keybindings. Comes in two versions.
dwb - a tiling web browser developed by an Arch Linux user (again, WebKit)
Conkeror - if you prefer Emacs bindings
Surf - another suckless product...
xombrero - "a minimalist web browser with sophisticated security features designed-in" (from the linked wiki page)
Try using Xournal:
Xournal is an application for notetaking, sketching, keeping a journal using a stylus. It is free software (GNU GPL) and runs on Linux (recent distributions) and other GTK+/Gnome platforms. It is similar to Microsoft Windows Journal or to other alternatives such as Jarnal, Gournal, and NoteLab.
Or if you don't mind a Java app, Jarnal:
Jarnal is an open-source application for notetaking, sketching, keeping a journal, making a presentation, annotating a document - including pdf - or collaborating using a stylus, mouse or keyboard. It is similar to Microsoft Windows Journal and to the earlier Mimeo whiteboarding and Palm notepad applications.
However, they are not so much of a whiteboard, but much more like note-taking applications.

For voice calls, you can try YATE. It was initially meant to work server-side, but with Qt-interface and heavily modular architecture, it works great as SIP, XMPP and H.323 client. It's also precompiled for Windows (if you've got any coworkers that use them) and works fine out of the box. On linux, you may try the latest git version, but compilation for h323 may be a bit tricky. AFAIK, there are also deb and rpm packages available.
There are many, many more things that you can do with YATE, you can find more info at their wiki and mailing list. Also, feel free to ask for anything on #yate channel on Freenode.
