0x01E6 Source T.38 Port

Use this TLV to specify the local T.38 port number for the fax relay. This TLV can be set on-the-fly. There is no default value for this TLV (i.e., no default T.38 port will be assumed). Therefore is imperative for the Host to resolve this port number as early as possible to ensure the proper fax relay operation. If this port number is not specified (in time), the fax relay will fail.
