Make an URL out of the Telephone field.

Hi,

I am trying to work out howto make an URL that is clickable out of the Telephone item in VSM the best option would be to have it work systemwide (e.g. when searching for a contactnumber etc) but ill be really happy if i can get it done in the call detail screen alone.

I pinpointed the field in the *.HTM export of the call detail screen but i dont know howto get it working:

<DIV class="Size-Small" iwtype="field-string" iwpropsize="Size-Small" fieldid="USER_REF$AR_PERSON.TELEPHONE" readOnlyIsreadOnly="1"><LABEL for=USER_REF$AR_PERSON.TELEPHONE>Telefoon</LABEL> <INPUT tabIndex=1 class="Field" readOnly name=USER_REF$AR_PERSON.TELEPHONE ismMandatory="false" ismReadOnly="1" maskid> </DIV></TD>

Is it possible to convert it to an URL from this point in the application or do i need to work from a different viewpoint?
