We are replacing PRI's with IP Flex. The IP Flex will give us a presence in other states. Customers call a local number in their state (555-444-3333) and we recieve the call on our IP Flex, 4 digit did (3333) that I will route to our operator. We can make local calls back to that state through the IP Flex if we send out CLID of our local number (555-444-3333). The only way I can see to do this is to program a key to send out (555-444-3333). Is there a way to send out CLID per NPA or RLI? We are CS1000, 4.5.
