The SIP Trunk Group can also have a Use the TCP Port Range configured that indicates window to configure a range of values to use when allocating TCP portsTCP ports to use for a specific SIP trunk group. 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 MSRP Session Setup for more information.
To View and Edit the TCP Port Range

Base Server Port | Indicates Specifies the start of the range of TCP ports to ports to use for media. The value ranges from this trunk group. This value must be within the system-level TCP port range. Values between 1-65534 are allowed and the default value is none. The value none indicates that this particular control is not applied and the port range specified by the system wide TCP Port Range settings are usedIf the value is set to none, the value is inherited from the system-level TCP Port Range. | Max Server Port | Indicates Specifies the end of the range of TCP UDP ports to use for RTP/RTCP media . The value ranges from for this trunk group. This value must be greater than the value of Base Server Port and within the system-level TCP port range. Values between 1-65534 are allowed and the default value is none. The value none indicates that this particular control is not applied and the port range specified by the system wide TCP Port Range settings are used.If the value is set to none, the value is inherited from the system-level TCP Port Range. |
