How does the U1900 reject some incoming calls?

To solve the problem, do as follows: 1. Run the show trunkgroup command to query the number of the trunk group through which the call is routed. 2. Run the following command to add a number change index for automatically adding 0 before the calling number: config add predeal index 2 changetype insert changepos 0 newdn 1 3. Run the config modify trunkgroup no 0 cliindex 2 command to associate the trunk group found in step 1 with the number change index configured in the preceding step. In this command, 2 is the number change index added in the preceding step.

When configuring the incoming call prefix, configure the calling number and called number change rules or the number mapping rule as required.

User A picks up the phone and dials *11*TN# (TN: number of user B for which user A answers the call).

1. By default, the U1900 cannot transfer an incoming call from an external user to another external user through the same trunk. 2. To enable this function, modifying the corresponding software parameter on the U1900: config softargu type 334 value 0. After software parameter 334 is modified, the U1900 can transfer an incoming call from an external user to another external user through the same trunk.

Yes.
