In item.php following lines are related to phone numbers:
<?php
$item_extra = veronika_item_extra( osc_item_id() );
?>
<?php
if(osc_item_user_id() <> 0) {
$item_user = User::newInstance()->findByPrimaryKey(osc_item_user_id());
}
$mobile_found = true;
$mobile = $item_extra['s_phone'];
if($mobile == '' && osc_item_user_id() <> 0) { $mobile = $item_user['s_phone_mobile']; }
if($mobile == '' && osc_item_user_id() <> 0) { $mobile = $item_user['s_phone_land']; }
if($mobile == '') { $mobile = __('No phone number', 'veronika'); }
if(trim($mobile) == '' || strlen(trim($mobile)) < 4) {
$mobile = __('No phone number', 'veronika');
$mobile_found = false;
}
?>
I could not find any issue there.
