That essentially means that not all telephone companies throughout the world are the same. The UK has its standards, the US has theirs, etc, etc. Your * fxo interface has to connect to the telephone company's pstn and use matching parameters "if" you want your fxo interface to work correctly. If they don't match you're likely to incur echo, weird signaling problems, etc. The standards often times include such things as the type of signaling used on the pstn line, the impedence (600 ohms is the US standard) used in designing the central office equipment and pstn cabling, etc. The x100p fxo card is limited by the chip design on the card to US standards, although some are using the card in the UK where different standards exist. The tdm04b (fxo) card uses a different set of chips, and has to be told which international standard to use. Since * seems to default to US standards, you will need to change that to uk standards. Might start by reviewing the contents of /usr/src/zaptel/zaptel.conf.sample looking for #loadzone=uk in that file. That file would have been copied to /etc/zaptel.conf on your system when you installed asterisk.
