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

Mon Nov 18 15:50:55 BDT 2013

Dear  Team  Member,

Thanks For your  Suggestion. I know voice  quality can not  improve  using
any firewall. firewall and  voice  quality is  both are different. i saw
if  network  any  firewall have  which  is  create  problem for  voice
termination.  but  firewall is  important to  secure the network. i want
to  know any  device which  can  support voice  termination.

and  for  voice  quality issue i  am not interest to  get  IPLC, without
IPLC how  i can  get  good  voice  quality from  public  internet in
Bangladesh. any one have any  Band width which  can  defer voice traffic
and  data  traffic  when it is  going  through any  pipe link. coz voice
traffic  will be  priority in  public  internet, how  i can   do  this, or
who can give  this  type  of  service.,

and  thanks  to  roman bhai, that  for  voice termination workshop agenda,.
It is  very  important for  Bangladesh.

FOr  routing we  are  using  Tier 1 provider. for  compression we  are
using  20 ms payload size for  g729 call.

Best Regards
Suvro
