Bandwidth limitations

• Ensure that the upload speed of the Internet connection is sufficient.

Most home-based Internet connections have an upload bandwidth limit.In some situations, this limit may be as restrictive in comparison to the download bandwidth.If you generate a large amount of network traffic over your Internet connection, this traffic can impede real-time communications.

• Ensure that an appropriate codec is being used.

The G.711 codec provides an 8 kHz sampling frequency and uses 64 kbps of bandwidth.Other codecs, such as G.726 (32 kbps), G.729 (8 kbps), and G.723.1 (6.3 kbps) use much less bandwidth at the expense of smaller sampling frequencies.If you are having audio quality issues for a specific codec, selecting a codec that uses less bandwidth may be a solution.

• Ensure that the LAN containing the remote computer with Interaction SIP Bridge has sufficient bandwidth available.Other systems on the LAN could transfer large amounts of data that could cause delays at the switch or wireless access point.
