Symptom: An outer-office user makes a call to an intra-office user through a trunk, and the called party's phone rings. When the called party does not answer the call within 20 seconds, the system announces that the call is restricted.
Step 1 Run the show trunkgroup command to view the call permission of the eSpace U1900 trunk of the original called party. If the trunk does not have the outgoing call permission, run the config modify trunkgroup no xxx restrict yes outgoingrights inter&local command to modify the permission.
Step 2 Run the show subscriber dn xx type newservice command to check whether intra-office users have the permission on the service of call transfer to the UMS voice mailbox on no reply (VOICEMAIL_CFU). If no, assign the permission.
Step 3 If the fault persists, contact the service provider.
