[Asterisk-Users] How does Asterisk handle connecting two IP end points?

2003-07-03 Thread Chip G
When a connection is carried between two IP end
points, does the Asterisk server incur CPU usage to
pass the voice bearing circuit between the two end
points? Is it possible to have Asterisk setup the call
but hand off the voice traffic to be handled directly
between the two end points?

Thanks!
Chip

IIRC asterisk by default will not participate in the call between two SIP phones.. It 
will help establish the session to the correct UA and then have nothing more to do 
with it unless the call is transferred to another UA in which case Asrerisk will again 
be involved in setting up the call.. 

So no when 2 SIP UA'a are connected there should be no CPU load on the Asterisk 
server..

Hope that helps..

Asterisk will be handling the signalling for the call, not the voice stream.
If you look at 'show channels' or 'sip show channels' while the call is up
you will see that Asterisk is aware of it.  Running tcpdump will show you
that the phones are still talking to Asterisk.

 So no when 2 SIP UA'a are connected there should be no CPU load on the Asterisk 
 server..

Well there is a minimum amount just for keeping track of the call, but per
call is very low.
