When the U1900 trunk-based call barring uses the 32-level customized call rights, how to configure the restrict parameter?

To configure password-based call barring on the U1980, perform the following steps: 1. Add the service rights. a. Add the password-based call barring service rights for users. b. Log in to the LMT command tree and access the config mode. c. In the command input area, run the config modify subscriber command. d. Set Dn to the user number that needs to use the password-based call barring service and PwdCallLimit to Yes. e. Click Execute. 2. Enable the call barring function. c. In the command input area, run the config modify prefix command. b. Set PwdCallLimit to Yes. c. Click Execute. 3. Set the password-based call barring prefix. a. In the command input area, run the config add prefix command. b. Set the call attribute to PwdCallLimit. c. Click Execute. To delete password-based call barring on the U1980, perform the following steps: 1. Log in to the LMT command tree and access the config mode. 2. In the command input area, run the config modify subscriber command. 3. Set Dn to the user number whose password-based call barring service needs to be deleted and PwdCallLimit to No. 4. Click Execute.

When U1900 or SoftCo users make outgoing calls through a trunk, the call duration cannot be restricted on the trunk. You can run the following commands to modify the service rights for users one by one or in batches to restrict the duration of a single call with external users. 1. To add the outgoing call duration restriction service right, run the following command: config modify subscriber dn [subpbxno <0-251>] [callertimelimit <0-300>] [calledtimelimit <0-300>] [number <>] Parameters of the outgoing call duration restriction service: dn: User number subpbxno: PBX number. The default value is 0. callertimelimit: Call duration when the user is the calling party, in minutes. calledtimelimit: Call duration when the user is the called party, in minutes. number: Quantity of user numbers to have the service modified in batches. Note: To view the restriction on the call duration, run the show subscriber command. If only the call duration restriction for the calling party is configured, the outgoing call duration is restricted only when the user is the calling user. If only the call duration restriction for the called party is configured, the call duration is restricted only when the user is the called user. If the call duration restrictions for both the calling and called parties are configured, the call duration is restricted regardless of whether the user is the calling or called user.
