<br>
<br>Relating to this thread, I'd like to know if there is any equipment that can shape up QoS traffic without affecting Non-QoS traffic at carrier networks where bandwidth is in hundreds of Mbps to tens of Gbps.

<br>> Dear� Team� Member,
<br>>
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.
<br>> 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.,
<br>>
<br>>
<br>> and� thanks�
to� roman bhai, that� for� voice termination workshop agenda,. It is� very�
important for� Bangladesh.
<br>>
<br>> FOr� routing we� are�
using� Tier 1 provider. for� compression we� are� using� 20 ms payload size for�
g729 call.
