asterisk users - Feb 2006 - Dial command to connect two channels and bypassasterisk server

If Asterisk is in the public network, it will work. The problem is when Asterisk
is behind NAT and one of the client is also behind the same NAT.

thanks for the information Peter, its really helpful. Also I have one more
question - do you have any idea how many such simultaneous calls can an asterisk
server handle (say running od 2.6Ghz, 1GB Ram, fedora machine)?
 
Thanks,
Nitin

You can enable this on a per-peer basis with:

sip peers:
canreinvite=yes

iax peers:
notransfer=no 

Check the iax.conf.sample and sip.conf.sample files for usage.

No, it won't. If one of the clients is behind a NAT firewall, you cannot
tell that firewall to start accepting media directly from the other client.

In some situations it _may_ work, but it is not reliable.
