That's because you have skype installed, skype Does this. It looks good from my view.(see attachement in the below post)

Try else to set the numbers between ""  or set the html code on in the table object and split the numbers so they won't look like a tel. nr.

like this:

137-46.314 becomes <span>137-</span><span>46.314</span>

or use this:

<span>137&shy; 46.314</span>

or

set this in the head section of the page: (step3 then properties, then expert tab, then head section)

<metaname="SKYPE_TOOLBAR"content="SKYPE_TOOLBAR_PARSER_COMPATIBLE"/>
