Voice Gateways
A voice gateway (VG) is another ATA device that enables incoming callers to call farther by using one
or more of its trunks, supporting two-stage dialing.
Incoming OBiTALK callers call the gateway first with a normal OBiTALK call, get the auto attendant,
and then dial the target number. For authentication, the auto attendant may ask the user to enter a
PIN before establishing the second call, or second stage.
A gateway is conceptually a trunk with its own digit map, and you can specify as many as eight
gateways. Address each gateway using its factory-assigned OBi Number and refer to a gateway and
its associated digit map with the short trunk name VG
n
and (Mvgn). You can use VG
n
and (Mvgn) in
call routing rules and digit maps just like other real trunks.
For more information on voice gateways, see the
Poly OBi Device Technical Reference
at Poly
Support.
Configure a Gateway for Direct Dialing
Configure a gateway with one-stage or direct dialing so that the caller can dial the target number
directly without going through the auto attendant.
Because a user can’t enter a PIN when direct dialing, you can configure an optional user ID and
password so the device can automatically authenticate with the gateway.
1. In the system web interface, go to Voice Services > Gateways and Trunk Groups.
2. In the Default column, clear the check boxes for AuthUserID and AuthPassword.
3. In the Value column, enter the values for AuthUserID and AuthPassword.
4. Select Submit.
5. Restart your system when you complete your changes.
Voice Gateway Examples
The following examples illustrate setting up voice gateways.
VG for all calls to numbers starting with 1
Setting up a voice gateway involves the following:
● Add the rule {(1xxx xxx xxxx):vg2} in the PHONE port's OutboundCallRoute parameter
to let the device dial out using VG2 when a caller dials any 11-digit number starting with 1.
● On the gateway side, add the corresponding rule {>(1 xxx xxx xxxx):sp1} to the PDMS-SP
Service InboundCallRoute parameter to make the call on its SP1 trunk.
You can change the last rule to {(290 333 100|200 444 101)>(1 xxx xxx xxxx):sp1}
if you want to limit the gateway to allow just the two stated caller numbers to make such calls.
