[Serusers] Re: Iqbal maybe you can help

[Ali Zaidi]

Hi,
 Thanks for reply, problem is fixed i reinstalled rtp from source, it seems 
that every element in place, only thing left is to put ser on public NOT in 
DMZ.
 I tried Mediaproxy before doing rtpproxy and i gave up. i will come back to 
mediaproxy some time in future.
 Thanks, 
Ali
