asterisk users - Mar 2005 - Comparing Callmanager to Asterisk

Callmanager does nothing than construct and tear down calls and the
actual RTP stream does not flow through the Callmanager but is direct
from IP device to IP device.  How does this work with Asterisk?  I read
something that lead me to believe that Asterisk has to process the
entire call, is this the case?

The simple answer is :
Depends on how you configure it. If you set your sip account as
"canreinvite=yes", it will behave as CallManager.

But it also depends on other things, like if it's SIP calling a SIP
you can have direct IP to IP flow. But a SIP calling an
IAX/MGCP/H323/ZAP will be different : Asterisk will stay in the middle
to handle conversion.

Even a SIP calling a SIP that use a different codec will have asterisk
stay in the path.

Wait, maybe I shouldn't have read this email to begin with !
