[bdNOG] Call Center Voice quality improve in public internet and call center security

Palash vai is absolutely right. 

There are lots of other factor like BW, Compression mechanism, routing
mechanism etc. that can cause the poor quality of voice.

Dear Mr. Suvro,

Your voice traffic is passing from source to destination and vice versa
using different carriers' network. So, it would be really difficult to
ensure End-to-End voice quality over the Internet. No one will guarantee for
it. Still IPLC is the best solution for it though it is quite costly. There
is one alternative solution is to get international MPLS connectivity if any
SP can provide you the same in BD. As far as I know, there is no firewall
device or software which can improve the voice quality over the internet.
