Morning Tom No they don't..well not in so many words anyway...snip from the support site below. I created the protocol rules mentioned....tcp in and out...the software connects....the receiving party can hear me, but I can't hear them. No blocks in the logs. If I enable the allow all protocol rule, it works flawlessly. Same log entries. FW Client is installed......tried netmon...both on my pc and the isa box....couldn't get my head round it at all Change your port settings If you are experiencing one-way audio (where you cannot hear the other party or they cannot hear you) you may need to adjust the port settings on your Internet Telephone. Please upgrade to the latest version of the Internet Telephone software, which allows you to use specific ports if required. To download the latest version of the Internet Telephone software, click here To change your port settings open the phone and click on the 'i' button. Select 'Options' then 'Advanced'. The following three options will be displayed. RTP/RTCP ports 6801/6802 - When the phone is installed the setting will default to 'RTP/RTCP ports 6801/6802'. This will work for the majority of networks, broadband and DSL connections. Use the following RTP/RTCP ports - this option allows you to select specific ports to match your firewall configuration. Use this option if ports 6801/6802 are unavailable on your network. If you require assistance with the selection of the ports please contact your system administrator. Dynamically allocated RTP/RTCP ports - This option is not recommended for general use as it selects ports randomly and is therefore unlikely to work on a network with a firewall. -----Original Message----- From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxxxxxxxxx] Sent: Sunday, November 23, 2003 11:52 AM To: Isa Weblist Subject: [isalist] RE: Callserve Internet phone http://www.ISAserver.org Hi Steve, Let me guess -- their support site says to "open a port" with your "open port" button. Right? Arrrg. Thanks!
