
Routing IP-to-Tel calls (including voice and fax) to specific endpoints based on called
line extension number (local number). To enable this functionality, in the Trunk Group
Settings table, set the 'Channel Select Mode' field to Select Trunk by
Supplementary Services Table for the Trunk Group to which the port belongs (see
'Configuring Trunk Group Settings' on page 519).

Mapping local numbers (line extension number) with global phone numbers (E.164).
The endpoint can be configured with two numbers – local and global. The local
number represents the endpoint's line extension number (e.g., PBX extension
number); the global number represents the corresponding E.164 number used for the
IP side in the SIP message:
•
IP-to-Tel calls: Maps the called global number in the user part of the SIP
Request-URI in the incoming SIP message to the local number sent to the Tel
side. For example, the device receives an incoming IP call with a destination
(called) that is a global number 638002 and then sends the call to the Tel side
with the destination number manipulated to the corresponding local number of
402.
•
Tel-to-IP Calls: Maps the calling (source) local number of the Tel side to the
global number sent to the IP side (in the From and To headers of the outgoing
SIP message). For example, if the device receives a Tel call from line extension
local number 402, it changes this calling number to 638002 and then sends the
call to the IP side with this calling number. This functionality in effect, validates
the calling number.
Note:
•
If you have configured regular Tel-to-IP or IP-to-Tel manipulation rules (see
'Configuring Source/Destination Number Manipulation' on page 555), the device
applies them before applying the local-global mapping rules configured in the
table.
•
To allow the end user to hear a dial tone when picking up the BRI phone, it is
recommended to set the Progress Indicator in the Setup Ack bit (0x10000=65536).
Therefore, the recommended value is 0x10000 + 0 x1000 = 65536 + 4096 =
69632 (i.e., set the ISDNInCallsBehavior parameter to 69632).
The following procedure describes how to configure the Supplementary Services table
through the Web interface. You can also configure it through ini file (ISDNSuppServ) or CLI
(configure voip > gateway digital isdn-supp-serv).

To configure endpoint supplementary services:
1. Open the Supplementary Services table (Setup menu > Signaling & Media tab >
Gateway folder > DTMF & Supplementary >
Version 7.2
27. Configuring Supplementary Services
Supplementary Services).
