Ranga, Can you tell me how you have implemented VoIP, I mean I would like to understand your network flow. I am in coming week is going to put VoIP. We have Toshiba digital EPABX and I am going to use FXO and FXS cards. Your suggestion would be really useful. Mukul ""Ranga"" wrote in message

Re: VoIP quality and Requirement [7:20497]

MJ here a table with some bandwidth figure for your traffic, as the others state 150ms is about the max delay after that then you can't guarantee quality. One major things to look for would be your qos on the local tail, read up on CBWFQ techniques they should help prioritise your voip traffic r

Re: VoIP quality and Requirement [7:20497]

Thanks Sasa, Well this will help me to calculate. Where you got all these stats ? are they in the same book that you have reffered, can u tell me the Author and publication also. Can we have RTP compression at 2 Internet routers if they are connected Via Internet ? Moreover normally delay is 500

Re: VoIP quality and Requirement [7:20497]

Mukul, usually, one voice packet is 20 bytes. Add to that 40 bytes for RTP+UDP+IP headers. So, for 8 Kbps voice stream, you would have to add 16 Kbps for overhead. That is total 24 Kbps. RTP header compression could shrink that to 11-12 Kbps, but it is possible to use it only on PtoP links, betwe

Re: VoIP quality and Requirement [7:20497]

Dear thomas, I understand that for very good quality the delay should not be more then 150 msec. But for Internet based Leased lines and that too spaneed across the different countries, the above figures are not just possible specially in Asian region. I have seen people having VoIP on msec 5
