When the U1960 serves as a tandem device, can the call source routing reanalysis function be implemented?

Call routes bind outgoing call prefixes to trunk groups to map outgoing call prefixes and trunks.

Configure call sources to enable users in the call sources to make outgoing calls through specified office routes. 1. Add call sources 1 and 2. config add callsource no 1 config add callsource no 2 2. Add users 5032?5049 to call source 1, and add new users 7000?7019 and non-DDI users 5050?5063 to call source 2. config modify subscriber dn 5032 callsourceno 1 number 18 config modify subscriber dn 5050 callsourceno 2 number 14 config modify subscriber dn 7000 callsourceno 2 number 20 3. Configure the route reanalysis function. When users 5032?5049 in call source 1 dial prefix 9 corresponding to office route selection code 1, calls are routed through the IAD332L-2. When users 5050?5063 and 7000?7019 in call source 2 dial prefix 9 corresponding to office route selection code 1, calls are routed through the PRA trunk. config add routeanalysis officeselectcode 1 callsourceno 1 officeno 4 config add routeanalysis officeselectcode 1 callsourceno 2 officeno 0

On the U1960 trunk gateway, configure a prefix (local call prefix) for the long number of a user on the registration gateway. The office route selection code used by the prefix is the same as that of the office route between the trunk gateway and the registration gateway. Note: The U1960 trunk gateway is used to forward the call request from the PSTN to the registration gateway of a user. To achieve so, the local call prefix for the called number must be configured on the U1960.

This problem occurs because the outgoing call permission of the incoming trunk is not enabled. For incoming calls through a trunk, configure the outgoing call permission of the trunk and configure number change for the calling numbers by running the following command: config modify trunkgroup no <0-6120> [restrict ] [outgoingright ] [clipredeal ] [cliindex <0-1023>] [domainType ] [callsourceno <0-255>] [trunklevel ]

The solution is as follows: Change the value of software parameter 269 to 0 and check whether a direct call to a carrier's number can be successful. If the call is rejected, the carrier network fails to authenticate the calling number, which leads to a failure to forward the call to an external user. In this case, contact the carrier to cancel the authentication.
