Configuring received numbers
The Public Received number length and the Private Received number length (refer to “Basic
parameters” on page 77 ) determine the number of digits that the SRG50 retains for call processing.
The retained digits are mapped to the DN using fields provided on the Target Lines panel. (For
more information on target lines, refer to “SRG50 terminology” on page 15 ).
To map received numbers to the DN
1 On the SRG50 Element Manager, navigate to Configuration > Telephony > Lines > Target
Lines (Figure 12) .
2 Select the target line of the DN for which you want to configure the received numbers.
3 In the Pub. Received # field, enter the retained received digits for calls originating from the
PSTN.
4
In the Priv. Received # field, enter the retained received digits for calls originating from the
private network (that is, the VoIP trunks). This number is usually the same as the DN.
Note: If the retained digits are the same as the DN, the fields ( Pub.
Received # field and Priv. Received # field) can be left blank.
