Not as much, but if you have any other outbound traffic over that
connection, it WILL still be a factor. Have you got a firewall/router
that provides any QoS features?

That might help to determine if the problem is in the Asterisk box or
the network. If you can make a local SIP client talk to your Phonejack
cleanly, and yet have problems with network connection, that could be a
factor.

Also, I recommend getting an account on IAXtel or FWD, and connecting a
softphone directly to those networks, and then into your system. That'll
stress your outgoing bandwidth, and potentially provide all kinds of
interesting information about what works and doesn't.

Cheers,

Jim.
