How much bandwidth for one SIP call?

How much bandwidth for one SIP call?

The amount of bandwidth you need to carry one call over SIP depends upon the CODEC you use.

Some Codec’s only use 40Kb per call but we will not sell this as the call quality is poor.

The calculation you should use is EASY – you need 100Kb per SIP call so for example 10Mb will carry up to 100 calls at the same time.
