Hello to the experts.
To start out with I don't know much about VOIP. We have a user who is
connected to DSL through Frontier with a speedstream 5200 adsl modem.
We are able to get out Axxess IP Phone Plus phone to show up on the
network.
The problem is that we are only getting one way communication. We can
hear the end party perfectly, they just cannot hear us over this
phone.
We believe we have opened all the appropriate ports on the firewall to
allow voice traffic through. We have tried using a packet sniffer,
and
unfortunately we don't see squat getting blocked from this user.

All help is greatly appreciated. Please post back to this original
string.
