[SR-Users] Unregister with Multiple Contacts

[Charles Phillips]

Sorted it.  I needed to loop through the contacts, then select the correct ruid based on $ci

For completeness, here is my solution:

reg_fetch_contacts("location", "$fu", "un_reg");
    $var(i) = 0;
    while ($var(i) < $(ulc(un_reg=>count))) {
        $var(ul_callid) = $(ulc(un_reg=>callid)[$var(i)]);
        $var(ul_ruid) = $(ulc(un_reg=>ruid)[$var(i)]);
        if ($var(ul_callid) == $ci) {
            xlog("L_INFO", "Unregistering contact $tu Ruid: $var(ul_ruid)\n");
            unregister("location", "$fu", "$var(ul_ruid)");
            $sht(regs=>$fU@$fd~$ci)=$null;
        }
        $var(i) = $var(i) + 1;
    }
