|Description:||How do I calculate the bandwidth required by one outbound call with my current requirements ?|
What is required for my upload and download bandwidth?
1. Using only G.729A/B codec from Digium.
2. Using only IAX2 Protocol IP Phones.
3. My Asterisk Server is placed in a Data Center.
Is my theory correct to say that IPv4 requires 20 octets, UDP requires 8 octets, RTP requires 12 octets (we are using IAX2 so there is no RTP)
so 28 x 8 = 224 bits and for 20milliseconds of 2 voice packets will require
224bits x 50= 11.2kbps and adding the 8kbps for using G.729AB 20ms will come to a total of 19.2kbps per outbound call.

The bug tracker is not a support forum. Please go through the mailing list archives on finding information on bandwidth usage or try one of the bandwidth calculators online, such as the asteriskguru.com one. Thanks.
