>I'm pretty sure that with IC Verify you can do a host "pre-dial". This means that just before you do the final authorization (i.e. while the user is preparing to finish their submission) you could have IC-V 'pre-dial' the VAS host. This saves you the dial-out time which is the longest part of the transaction. The VAS host will keep the connection up for some interval (which you can't control but you can test) usually about 30 secs before disconnect. If IC-V doesn't have the pre-dial function, well then you can use a net-based c/c authorization service provider or pay for a (gulp!) leased-line connection to VisaNET. The development lab at Vital Processing Services (they now control VISANet) at 1-480-333-7878 may also be able to point you in other directions in terms of companies providing other solutions.
