Garth<br><br>In Cape Town we're assisting at a site where we have two PRI's coming in from Telkom and going out to a legacy PBX, CPU is a 2.8Ghz the card is a Digium TE406P so that the echo cancellation is handled by the hardware rather than server. Monitoring is at teh channel level and with Asterisk
1.2 you should look at MixMonitor record audio & mix natively as the call is in progress to avoid the need to spawn
external processes which will cause cpu usage spikes.<br><br>The set-up has to be in serial, you can't 'vampie' the lines. So this is potentially a point of failure so we install the Junghanns ISDNguard that can take in four BRI or PRI and send our four to an Asterisk server and four to a back up device. A serial connection listens for a heart beat on the Asteirsk server and switches over on failure.

Hi All<br><br>Does anyone have any ideas around what processing power is needed when<br>bridging PRI channels and recording?<br>I am not sure how the bridging takes place with and without recording?<br>I basically have a situation like this:
<br><br> Telko <----> Asterisk <-----> Legacy PBX<br><br>Where the lines are PRI's between Telko and Asterisk and Asterisk and<br>the Legacy PBX.<br>At what level does bridging happen? Do the streams get passed directly
<br>between to two PRI ports? How would recording effect this? Tap into<br>the streams etc?<br>If someone could explain a bit more on the architecture around this,<br>that would be great.<br><br>Thanks<br>Garth<br><br>_______________________________________________
