We have installed a new Samsung 100 with PRI and the customer has a problem when they pause in the middle of dialing for more than three seconds between digits. They will get a recording " cannot complete your call as dialed". We have had no luck with the carrier in increaseing the interdigit timing. We have turned on the LCR feature so the digits will be pulsed all at once and this is working fine. Has anyone had this problem and solved it another way? I am afraid that in future installations I may have reason not to use LCR.
