Thank you. It might be the right way.
Unfortunately I am not familiar with the syntax of php. 
When I put the code around it as you wrote, I will see the code written on the page.
Perhaps it is just a small change.
 <{if $annonce.suspend > 0}>  
<{$smarty.const._MD_CATADS_PUB_SUSP}> <{else}> <{$smarty.const._MD_CATADS_CONTACT}>  
<{$annonce.msg_contact}> <{$annonce.maillink}> <{$annonce.pmlink}> <{$annonce.phone}><{/if}>  
It would be the optimum, when the guest would see a message like "you must be a registered member to answer ..." instead of the buttons.
