I need to understand the usage of voice codec:
what i know the analog line bandwidth is 64 kbps when iam using g711ulaw codec for example or g792 it's will compress the voice traffic to 8 kbps is that mean 1 analog line can handle 8 calls in one time ??
is 8 analog line enough for a company has 80 employee ??
no. one RTP stream per analog port, be it g729 or g711.
80 people I would aim for 15-20% concurrency, but 15% would be enough, so 15% of these employees would be on an external call at the same time.
no one rtp stream per analog port be it g711 or g729
i would go 15% concurrency, i.e. 15% of your 80 employees on an external call at any given time.
