[Asterisk-Users] PRI Bridging and Recording

[Garth van Sittert]

Hi All

Does anyone have any ideas around what processing power is needed when 
bridging PRI channels and recording?
I am not sure how the bridging takes place with and without recording?
I basically have a situation like this:

        Telko <----> Asterisk <-----> Legacy PBX

Where the lines are PRI's between Telko and Asterisk and Asterisk and 
the Legacy PBX.
At what level does bridging happen? Do the streams get passed directly 
between to two PRI ports?  How would recording effect this?  Tap into 
the streams etc?
If someone could explain a bit more on the architecture around this, 
that would be great.

Thanks
Garth
