Bandwidth Requirement

[Brainchild]

We are in the process of setting up a call center in India. Can anyone on the forum help me to decide on my bandwidth requirement. We have already bought the calling minutes from a vendor who does not provide broadband connectivity. For 10 seater outbound process, is it necessary to go with IPLC? We are trying to manage with broad band. But my current connection gives me latency of 280 to 500 ms at varying time of the day, which I believe is not sufficient for good quality calls, can anyone help me on this ASAP please,

Regards

Hi,

Ideally for 10 seaters if you are using VoIP you can take 24 Kbps per call over WAN using G729 Codec for compression for 10 seater 24*10=240Kbps

again it depends on calling ratio i.e. how your dialer will pace calls to your agents i.e. if there are 10 agents and if the pacing is 1:2 i.e. per agent 2 calls then you can calculate the bandwidth per call as per the ratio.

You can use 1 Mbps for 10 Agents which works perfectly with G729 but I would recommend to go for a 2 Mbps ILL - Dedicated or Private link so that additional bandwidth comes handy when you do a expansion.

Broad band is not suitable for sending calls due to many factors like delay, latency and drops it is ideal to go for a lease line - dedicated

300 ms is bench mark for VoIP calls if the latency goes beyond 300ms then there will be issues like voice breaks , cracks ,echo and jitter
