I have several portable touch computers with Ubuntu Linux 10.04LTS Lucid Lynx, the processor architecture is "i386". I used the TWINKLE VOIP client, and through SIP I can call these devices from an IP phone, and in the same way I can also call an IP phone from touch screen computers.
The problem is that I need a keyboard every time I need to dial a number. No on-screen keyboard function.
Is it possible to dial a sip number directly from a Linux terminal?
If possible, I will include the script in a small GUI application, so that the user will call numbers with my touchscreen GUI application.
