local-bypass

Hi

What does local-bypass do? I noticed this is something to do with hairpin/dsp etc. Thanks

Re: local-bypass

Local by-pass allows local calls (calls between voice ports on a router or concentrator) to bypass (not use) the DSP to minimize use of system resources.

Re: local-bypass

Thanks. Just use the following illustration to help me understand. Does that mean if we use bypass the dsp won't be used in the following cases:

1. call between analog 1 and anlog 2 not need dsp at all?

2. Hairpin

scenario1:

analog1-(fxs-r1-pri)-pstn-analog2

scenario2:

hairpin case: call coming into one pri from pstn and route back to pstn using the same pri.
