GUI for Asterisk


I already have Asterisk1.6 installed on my system. The OS used is Ubuntu8. I now want to use some GUI tools so that I can configure Asterisk further.

Can you suggest me some ways of doing it.

I have tried to use

  1. FreePbx
  2. AsteriskNOW

But both seem to install the complete Asterisk from scratch.

Are there any other free(GPL) tools which can be installed on top of Asterisk
