VoIP Bandwidth Calculation

VoIP Bandwidth Calculation

(OP)
We are in the process of linking or remote sites with a layer 3 MPLS links. The main office has a 1G connection and out of it 5MB is configured as EF. The rest of the sites are on 200MB links with 1MB EF. We hope to mark all Voice Traffic as EF (DSCP 46).

My quesiton is simple: How many g711 calls (conversations) can I put on a 5mb (ef) link? Even though G711 is 64K -22k overheads = 87k (approx). When calculationg bandwidth you x2 87K = 174k (approx).

1. When calcualting bandwidth, do you calculate bi directional for a coversation?
2. How many calls can happen simulteneously on a 5mb link?
3. If the link is full duplex, will this rule change.

Appreciate any help and explanation. I just need to justify my recomendaitons to the business.

Yes

You would only use full duplex.

Best bet, use a online bandwidth calculator, there are plenty out there.
