Use the TCP Port Range window to specify the range of port numbers allowed for TCP media for the system. This port range is used by the SBC to advertise the TCP ports on which it can accept connections. A unique unused port from this range is included in the SDP media line in the offer or answer sent towards an MSRP UA. Refer to Configuring MSRP Support for more information.
On the SBC main screen, go to All > System > Media > TCP Port Range. The TCP Port Range window is displayed.
