How to configure the U1900 so that the short numbers of outgoing calls are displayed?

For details, see section 6b "Configuring Prefixes" in the eSpace UC V200R003 IPT Quick Configuration Guide .

You can configure the maximum length of the called number when configuring outgoing prefixes.

Configure the call source to enable users in the call source to make outgoing calls through a specified office route. The specific configuration is as follows: 1. Run the following commands to add call sources 1 and 2: config add callsource no 1 config add callsource no 2 2. Run the following commands to add users 5032 to 5049 to call source 1 and add users 7000 to 7019 to call source 2: config modify subscriber dn 5032 callsourceno 1 number 18 config modify subscriber dn 7000 callsourceno 2 number 20 3. Run the following commands to add rerouting analysis. In this way, when users 5032 to 5049 in call source 1 dial prefix 9 corresponding to the office route selection code 1 to make outgoing calls, calls are routed through office route 4, and when users 7000 to 7019 in call source 2 dial prefix 9 corresponding to the office route selection code 1 to make outgoing calls, calls are routed through office route 0. config add routeanalysis officeselectcode 1 callsourceno 1 officeno 4 config add routeanalysis officeselectcode 1 callsourceno 2 officeno 0

The following uses the U1930 as an example. Commands for modify the outgoing call rights for a single user: [%eSpace U1930(config)]#config modify subscriber dn 6101 priorlevel default operateout del outgoingrights local //Delete the outgoing local call right for user number 6101. [%eSpace U1930(config)]#config modify subscriber dn 6101 priorlevel default operateout del outgoingrights local&ddd //Delete the outgoing local and national toll call rights for user number 6101. [%eSpace U1930(config)]#config modify subscriber dn 6101 priorlevel default operateout add outgoingrights local //Add the outgoing local call right for user number 6101. [%eSpace U1930(config)]#config modify subscriber dn 6101 priorlevel default operateout add outgoingrights local&ddd //Add outgoing local and national toll call rights for user number 6101. [%eSpace U1930(config)]# config modify subscriber dn 6101 priorlevel default operateout add outgoingrights Inter&local&ddd //Modify the outgoing call rights for user number 6101 to outgoing intra-office, local, and national toll call rights. Commands for modify the outgoing call rights for multiple users in batches: [%eSpace U1930(config)]#config modify subscriber dn 6101 priorlevel default operateout del outgoingrights local number 100 //Delete the outgoing local call right for 100 user numbers starting from 6101. [%eSpace U1930(config)]#config modify subscriber dn 6101 priorlevel default operateout add outgoingrights local number 100 //Add the outgoing local call right for 100 user numbers starting from 6101. %eSpace U1930(config)]# config modify subscriber dn 6101 priorlevel default operateout add outgoingrights Inter&local&ddd number 100 //Modify the outgoing call rights for user numbers starting from 6101 to outgoing intra-office, local, and national toll call rights. Note: inter indicates the intra-office call right, local indicates the local call right, ddd indicates the national toll call right, and idd indicates the international toll call right.

The calling number is displayed as a short number by default. You cannot modify the configuration to change the short number to a PSTN number.
