Mon Sep 15 06:36:45 CEST 2014

Hi,

It appears that my last two messages have gone in moderation. Anyways, Can
you please tell me, how can i setup rtpengine on Ubuntu machine? After
installation - What configurations will i have to change?

I have lurked the internet a lot but did not find any tutorial on this.
Would appreciate any help on this.

Regards
