SIP User's Manual 18. GW and IP to IP
5. Define IP Group #4 for the remote IP-PBX users:
a. From the 'Type' drop-down list, select USER.
b. In the 'Description' field, type an arbitrary name for the IP Group (e.g., IP-PBX).
c. In the 'SIP Group Name' field, enter the host name that is used internal in the
device's database for this IP Group (e.g., RemoteIPPBXusers).
d. From the 'Serving IP Group ID' drop-down list, select 3 (i.e. the IP Group for the
IP-PBX).
Figure 18-57: Defining IP Group 4
Note: No Serving IP Groups are defined for ITSP-A and ITSP-B. Instead, the
Outbound IP Routing table (see 'Step 9: Configure Outbound IP Routing' on
page 377) is used to configure outbound call routing for calls originating from
these ITSP IP Groups.
18.9.2.6 Step 6: Configure the Account Table
The Account table is used by the device to register to an ITSP on behalf of the IP-PBX. As
described previously, the ITSP's requires registration and authentication to provide service.
For the example, the Served IP Group is the IP-PBX (IP Group ID #3) and the Serving IP
Groups are the two ITSP's (IP Group ID's #1 and #2).
