In Program 0928, set trunk group 1 for routing to a VoIP trunk.

Route Table No. 1 — Trunk Group 101
VoIP Trunk Group 101 will point to Program 0928, table (entry) 1.
As a result, if a user dials the VoIP number 401, trunk group 101 is referred by F-Route. Then, the system checks the Program 0928 set-
ting and seizes a trunk from system trunk group 10. The call goes to address 192.178.10.2.
Special programming will be required if a remote system has two or more VoIP PCBs.
Incoming Calls
When an incoming call is detected, the VoIP PCB will be searched for an idle port on the VoIP PCB. An incoming call can be connected
to any of the ports on the PCB, so the trunk service type has to be the same for all the trunks on the same PCB.
Basic system settings are essentially the same as ISDN trunks. The routing programing is also the same. However, as incoming calls
may have a called party number, it is recommended that DID service type be used (Program 0901, Items 14-17 and 32-35 set to 3).
Incoming calls may not have a called party number or the number may not exist in the DID table. When this occurs, the DID Error Routing
will be used. Refer to the
i-Series Software Manual
, P/N 92000SWG**, for information on programming DID trunks.
DID Error Routing Settings
In the past, if a called party number did not exist in the Setup message, ISDN DID trunks would reject the calls. With the VoIP
H.323 incoming calls, DID error routing is used to handle the Setup message for calls without a called party number.
For example, DID Table Area #1 is being used, routing to trunk ring group 10.

The first table is 0001.
