asterisk users - Dec 2007 - new Asterisk installation with openvox 1.2 or 1.4?

Hi

i need to install a server with this hardware:

1	OpenVox B800P
1	OpenVox A800P01
4	OpenVox FXS-100	FXS100	
4	OctWare SoftEcho	SOFTECHO
  	
Do you suggest 1.2 or 1.4 branch?

Is now 1.4 stable ?

I've tried 1.4 the last year but i've experienced many problems with
misdn drivers.

Thanks
