for example, the long number is 1234567890, 7-digit is 4567890;4-digit is 7890

1. Config the CalleePrefixConfiguration 456 with Intra-officecall

Hi,

please see below configuition guide for configuring prefix:

When you control outgoing call rights of users by configuring prefixes, pay attention to the following:

  1. Prefix rights must be distinguished clearly. That is, prefixes with lower rights cannot contain prefixes with higher rights. For example, a prefix with the local call right cannot contain a prefix with the ddd call right.
  2. Configure the minimum outgoing call rights for users based on the service requirements.
The following assumes that the local call, national toll call, and internal toll call prefixes for outgoing calls from the PBX1 to PSTN are 9, 90, and 900 respectively. When a user dials 9 + international toll number, the gateway matches outgoing prefix 900 because an international toll number generally starts with 00. The gateway determines that the user does not have international toll call rights and restricts the call. This prevents toll fraud.

Common toll fraud mode: A user dials 9 + nest dialing prefix of the carrier (such as 17900, 17901, 17909, 17911, 17951, 10193, 12593, 197, 11808) + international toll number to make an outgoing call.

Prevention measure:
  1. Confirm all dialing modes that will be considered as international toll calls with the carrier.

  2. Configure international toll prefixes required by services as idd prefixes.
  3. If there are international toll prefixes that are not required by services, ask the carrier to restrict the outgoing call rights of these prefixes. If the carrier cannot restrict the outgoing call rights of these prefixes, configure rights that no intra-office user has for these prefixes.
  4. On the gateway, configure prefix 9 as a local prefix, 9 + nest dialing prefix + 0 as a national toll prefix, and 9 + nest dialing prefix + 00 as an international toll prefix.

    For example, when an intra-office user dials 9 + 17909 + international toll number, the gateway matches international toll prefix 91790900. The gateway determines that the user does not have international toll call rights and restricts the call. This prevents toll fraud.

Configuration example: All calls with call numbers starting with 00, 1790900, 1180800, 462600, and 44000 are considered as international toll calls. The carrier cannot restrict the outgoing call rights of these prefixes. Users always dial prefix 9 to make outgoing calls to the PSTN. When making international toll calls, users always dial prefix 900 or 917909. The idd prefixes should be configured as follows:

  • 9: local
  • 90: ddd
  • 900: idd
  • 91790900: idd
  • 91180800: cus31. Use 32-level customized rights to control outgoing calls. No intra-office user has the cus31 outgoing call right.
  • No prefix for outgoing calls to the PSTN starts with 4.
The following describes how to configure prefixes 9, 90, 900, 917909, 9179090, and 91790900.
  1. Log in to the LMT and access the command tree.
  2. Configure the number change index 1:the first digit of the number is deleted.

    config add predeal index 1 changetype delete changepos 0 changelen 1

  3. Set the call attribute of prefix 900, 91790900 to idd.

    config add prefix dn 900 callcategory basic callattribute idd cldpredeal yes cldindex 1 officeselectcode 3 minlen 0 maxlen 32

    config add prefix dn 91790900 callcategory basic callattribute idd cldpredeal yes cldindex 1 officeselectcode 3 minlen 0 maxlen 32

  4. Set the call attribute of prefix 90 to ddd.

    config add prefix dn 90 callcategory basic callattribute ddd cldpredeal yes cldindex 1 officeselectcode 2 minlen 0 maxlen 13

  5. Set the call attribute of prefix 9 to local.

    config add prefix dn 9 callcategory basic callattribute local cldpredeal yes cldindex 1 officeselectcode 1 minlen 0 maxlen 12

  6. Set the call attribute of prefix 91180800 to idd and cus31.

    config add prefix dn 91180800 callcategory basic callattribute idd&cus31 cldpredeal yes cldindex 1 officeselectcode 1 minlen 0 maxlen 32
