Here's a web interface (click-to-dial) for creating .call files (part of 
XRMS, an open source CRM package):

function lookupCID($thelookupCID) {

        $lookupCID_sip_array = parse_ini_file("/etc/asterisk/sip.conf", 
true);

        while ($v = current($lookupCID_sip_array)) {
                if (isset($v['crm_username'])){
                        if($v['crm_username'] == $thelookupCID) {
                                $thelookupCID = key($lookupCID_sip_array);
