[Asterisk-Users] GUI Tool

[m. smadi]

hi;

I am looking for  a well proven GUI tool to compose *.conf files 
including SIP, IAX2 and Zap channels.  I am considering
Asterisk Management Portal 
<http://www.voip-info.org/wiki-Asterisk+Management+Portal> and DeStar 
and ACTOS <http://www.voip-info.org/wiki-ACTOS>

Does anybody have exerience with any of these tools or can recommend one 
tool over the others?

thanks
