what is the codec used for ?

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 ??

Thank you

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.

i would go 15% concurrency, i.e. 15% of your 80 employees on an external call at any given time.

Re: what is the codec used for ?

When you say analog line, is it pure POTS (FXO to be specific). If yes, one port can only handle a single call, inbound or outbound. So for 8 analog lines/8 analog ports, you can have a max of 8 calls inbound and outbound inclusive. I believe the solution would be underwhelming for 80 employee. You might need to look into a TDM circuit or better yet get a SIP trunk.
