Hello to the experts.\nTo start out with I don't know much about VOIP. We have a user who is\nconnected to DSL through Frontier with a speedstream 5200 adsl modem.\nWe are able to get out Axxess IP Phone Plus phone to show up on the\nnetwork.\nThe problem is that we are only getting one way communication. We can\nhear the end party perfectly, they just cannot hear us over this\nphone.\nWe believe we have opened all the appropriate ports on the firewall to\nallow voice traffic through. We have tried using a packet sniffer,\nand\nunfortunately we don't see squat getting blocked from this user.\n\nAll help is greatly appreciated. Please post back to this original\nstring.\n\nScott\nLost in communication.
