You have implemented 5-digit forced authorization codes to all international route patterns on Cisco Unified Communications Manager.
Your users report that after entering the FAC codes, they must wait for more than 10 seconds before the call is routed.
Which procedure eliminates the wait time?

Because it immediately stops taking digits and route the digits to CUCM, otherwise the call occurs after the interdigit timer expire which is 15 seconds by default.

The issue described in the question indicates that there is a delay of more than 10 seconds before a call is routed after entering the forced authorization codes (FAC) for international calls. This delay can be caused by various factors such as overlapping route patterns, incorrect configuration of service parameters, or delays in call setup by the long-distance telephone service provider.
Option A suggests that the delay may be due to overlapping route patterns. When a call is placed, Cisco Unified Communications Manager looks for a matching route pattern to determine the destination. If there are overlapping route patterns, the system may need to take extra time to decide which route pattern to use. Therefore, it is recommended to check for any overlapping route patterns and remove them to streamline the call routing process.
Option B suggests that reducing the T-304 timer in the Cisco Unified Communications Manager Service Parameters may help to reduce the wait time. The T-304 timer determines the time that the system waits for the user to input digits before sending the call to the route list or route pattern. By reducing the timer to 5000 milliseconds, the system may send the call to the route list or pattern faster, resulting in a shorter wait time.
Option C suggests that the delay may be caused by the long-distance telephone service provider. In this case, it is recommended to contact the service provider and request that they reduce the call setup time to 5 seconds.
Option D suggests that adding a hash (#) sign to the end of the FAC codes may signal the end of dialing, allowing the system to process the call faster. However, this option may not necessarily eliminate the wait time, as the delay may still be caused by other factors.
Option E suggests that educating the users to press the # sign after entering the FAC codes may help to reduce the wait time. By doing so, the system may process the call faster, as it can detect the end of dialing and send the call to the route list or pattern sooner.
Overall, the best option for eliminating the wait time would depend on the specific cause of the delay. If the delay is caused by overlapping route patterns, option A would be the most effective. If the delay is caused by service parameters, option B would be the best choice. If the delay is caused by the long-distance telephone service provider, option C would be recommended. Options D and E may be helpful in certain situations, but they may not be effective in all cases.
