–
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.
l
In the actual configuration, configure whether the phone number reported by the
MA5616 contains the centrex prefix according to the local standards. This function is
controlled by the one hundred and fourty-eighth control point of the Sipprofile. The options
of the parameter are 0 and 1, where 0 indicates that the phone number does not contain the
centrex prefix and 1 indicates that the phone number contains the centrex prefix. By default,
this parameter is configured to 1.
Precaution
The MA5616 supports the configuration of the centrex prefix through one of the following two
methods:
l
Method 1: Run the
sippstnuser servicedata parameters set
command to configure the
centrex prefix and centrex attributes of a centrex.
l
Method 2: Run the
local-digitmap add
command to add a direct centrex digitmap or a two-
stage centrex digitmap.
CAUTION
The system does not support the adding of a direct centrex digitmap and a two-stage centrex
digitmap at the same time. Add the corresponding digitmap according to the requirements.
When you add a direct centrex digitmap, the centrex attribute of the system is direct centrex.
When you add a two-stage centrex digitmap, the centrex attribute of the system is two-stage
centrex.
l
If both the operations are carried out successfully through the preceding methods, the
system adopts the configuration obtained through the
sippstnuser servicedata parameters
set
command.
l
If method 2 is adopted, the MA5616 uses the centrex digitmap to match the centrex prefix,
and then uses the call digitmap, namely, the normal digitmap, to match the phone number
dialed by the user.
Procedure
Step 1
Check whether the value of the control point of the Sipprofile needs to be changed. If the value
needs to be changed, run the
interface sip
command to enter the SIP interface mode, and then
run the
sipprofile modify
command to change the value to the required one.
Step 2
Configure the centrex call function of a centrex.
l
Configure the centrex call function by using method 1 in Precaution:
1.
In ESL user mode, run the
sippstnuser servicedata parameters set
command to configure
the centrex prefix and centrex attributes of a centrex.
2.
Run the
display sippstnuser servicedata
command to check whether the configuration of
the centrex parameters of a centrex is the same the planned configuration.
