(Optional) Configuring the Centrex

Centrex refers to a virtual user group. The MA5600T/MA5603T/MA5608T supports the following functions: Members in a centrex can call each other by dialing short numbers, and members in a centrex can call the members outside of the centrex by dialing centrex prefix + the complete phone number. Generally, a softswitch issues centrex parameters. If a softswitch does not issue centrex parameters, use the parameters preset on the MA5600T/MA5603T/MA5608T. These parameter values must be the same as these on the softswitch.

Context
  • Centrex prefix: When attempting to call a user in another centrex group, a user must dial the centrex prefix before dialing the called number. A centrex prefix contains 0 to 9 digits.
  • The function that the members in a centrex can call each other by dialing short numbers need not be configured on the MA5600T/MA5603T/MA5608T through the command line interface (CLI).
  • The function that the members in a centrex can call the members outside of the centrex by dialing centrex prefix + the complete phone number can be supported only when the SIP protocol is used.
  • The centrex attribute of a centrex can be direct centrex or two-stage centrex. The similarity and difference are as follows:
    • Similarity: When the members in a centrex need to call the members outside of the centrex, they must dial the centrex prefix.
    • Difference: If the centrex attribute is set to two-stage centrex, the members in a centrex can hear the dial tone again after dialing the centrex prefix. If the centrex attribute is set to direct centrex, no out-group dial tone is played.

Procedure

  1. Configure the centrex call function for a centrex group.

    The MA5600T/MA5603T/MA5608T supports the configuration of the centrex prefix through one of two methods. In method 1, configure the centrex prefix and centrex attributes for a single user in ESL user mode. In method 2, configure the centrex prefix and centrex attributes for all the users in global config mode. When both methods are used, method 1 takes effect.

    • Use method 1:
    1. In ESL user mode, run the sippstnuser servicedata parameter set command to configure the centrex prefix and centrex attributes of a centrex group.
    2. Run the display sippstnuser servicedata command to check whether the centrex parameter settings of a centrex are the same as the data plan.
    • Use method 2:
      NOTE:

      If method 2 is used, the MA5600T/MA5603T/MA5608T uses the centrex digitmap to match the centrex prefix, and uses the call digitmap, or the normal digitmap, to match the phone number dialed by a user.

    1. In global config mode, run the local-digitmap add command to configure a direct centrex digitmap or a two-stage centrex digitmap.

      NOTE:
      • The system does not support the adding of a direct centrex digitmap and a two-stage centrex digitmap at the same time. Add a digitmap based on site requirements.
      • When you add a direct centrex digitmap, the system centrex attribute is direct centrex. When you add a two-stage centrex digitmap, the system centrex attribute is two-stage centrex.

    2. Run the display local-digitmap command to check whether the local digitmap is the same as the data plan.
  2. Check whether the value of the sipprofile control point 148 is the same as the data plan.

    Run the display sipprofile syspara detail command to check whether the value of control point 148 is the same as the data plan. If they are different, run the sipprofile modify command in SIP mode to change the control point value.
    NOTE:
    • The sipprofile control point 148 can be set to 0 or 1. When it is set to 0, a phone number does not contain a centrex prefix; when it is set to 1, a phone number contain a centrex prefix. By default, it is 1.
    • Run the if-sip attribute basic sipprofile-index 0 command to specify a user-defined profile for the current SIP interface, and run the sipprofile modify command to change the value for the sipprofile control point 148.

MA5600T/MA5603T/MA5608T

Assume that the centrex prefix of the MA5600T/MA5603T/MA5608T user with phone number 88627792 is 8100, the centrex attribute is two-stage centrex, and the control point of the Sipprofile uses the default value.

To configure the centrex call function for such a user by using method 1, do as follows:

huawei(config)#esl user
huawei(config-esl-user)#sippstnuser servicedata parameter set 0/2/1 telno 88627792 centrexprefix 8100 centrexflag dialsecondary
huawei(config-esl-user)#display sippstnuser servicedata 0/2/1 telno 88627792
  ----------------------------------------
  F /S /P                 : 0/2/1
  telno                   : 88627792
  centrexno               : -
  centrexprefix           : 8100
  centrexflag             : dialsecondary
  mwimode                 : deferred
  hottime(s)              : 100
  hotlinenum              : -
  dialtone                : normal
  cfbnum                  : -
  cfnrnum                 : -
  cfunum                  : -
  cfnrtime(s)             : 100
  displayname             : -
  permanent-hold-mode     : norecall
  permanent-hold-time(s)  : 20
  ---------------------------------------------------

To configure the centrex call function for such a user by using method 2, and plan the digitmap body to (8100) and the digitmap name to huawei1 for the two-stage centrex digitmap according to the centrex prefix, do as follows:

huawei(config)#local-digitmap add huawei1 second-centrex (8100)
huawei(config)#display local-digitmap all
  ------------------------------------------                                    
  Name    : huawei1                                                             
  Type    : second-centrex                                                      
  Body    : (8100)                                                              
  Protocol: sip                                                                 
  ------------------------------------------   

(Optional) Configuring the System Parameters

This topic describes how to configure the system parameters including the overseas version flag and message waiting indication (MWI) mode according to the local standards to ensure that the response of the user terminal complies with the local standards.

Procedure

  1. Run the system parameters command to configure the system parameters.
  2. Run the display system parameters command to check whether the system parameters are the same as those in the data plan.

Example

To configure the overseas version flag (system parameter 1) to Hong Kong (parameter value 1), do as follows:

huawei(config)#system parameters 1 1                      
huawei(config)#display system parameters 1
  ----------------------------------------------------------------------------- 
  Parameter name index: 1     Parameter value: 1                                
Mean: Overseas version flag, 0:China, 1:HongKong, 2:Brazil, 3:Egypt,
4:Singapore, 5:Thailand, 6:France, 7:Britain MSFUK, 8:Britain ETSI, 9:Bulgaria,
10:Reserved, 11:Austria, 12:Hungary, 13:Poland, 14:Turkey, 18:Belarus,
20:Germany                                  
  ----------------------------------------------------------------------------- 

(Optional) Configuring the Overseas Parameters

By default, the overseas parameters are configured according to the Chinese standards. In the actual service configuration, the attributes such as the upper and lower thresholds of the flash-hooking duration can be configured according to the local standards to ensure that the response of the user terminal complies with the local standards.

Procedure

  1. Run the oversea parameters command to configure the overseas parameters.
  2. Run the display oversea parameters command to check whether the overseas parameters are the same as those in the data plan.
Example

To set the upper flash-hooking threshold (overseas feature parameter 0) to 800 ms (in compliance with the Hong Kong standard) and the lower flash-hooking threshold (overseas feature parameter 1) to 100 ms (in compliance with the Hong Kong standard), do as follows:

huawei(config)#oversea parameters 0 800
huawei(config)#oversea parameters 1 100
huawei(config)#display oversea parameters
{ <cr>|name<U><0,99> }: 1                                                          
                                                                                
  Command:                                                                      
          display oversea parameters 1                                           
    ----------------------------------------------------------------------------- 
  Parameter name index: 1     Parameter value: 100                               
  Mean: Hooking lower threshold(ms), reference: China:100, HongKong:100
