Making Calls with the VIU-323
Making a BRI call through Two Gateways to a Remote LAN
Endpoint
If the bandwidth of the calling VIU-323 is 2x64 Kbps and the receiving VIU-323's
bandwidth is 384 Kbps, dial:
!
The first gateway's service number, followed by
!
The phone number of the remote gateway;
When you are prompted by an IVR message (for example), dial:
!
The extension of the remote VIU-323, followed by
!
The dialing suffix.
Example
80 7654321 (IVR prompt) 4444 00
Where 80 is the service prefix of the first gateway, 7654321 is the phone number of the
remote gateway, 4444 is the extension of the remote VIU-323, and 00 changes the receiving
VIU-323's bandwidth to 2x64 Kbps.
Changing Both Incoming and Outgoing Bandwidth
In some cases, you must dial both a prefix and a suffix. Because the network sets bandwidth
availability at any particular time, you may have to use lower bandwidths during peak
hours. You may therefore have to use a prefix to force the outgoing call to a lower
bandwidth and a suffix so that the VIU-323 you are calling can receive the call. Remember
that you can only use a suffix when calling from one VIU-323 to another.
Example
If both VIU-323's are set to 384 Kbps, but the call doesn't go through, send the call at 128
Kbps by dialing the following:
#10 80 7654321 (IVR prompt) 4444 10
Where #10 changes the calling VIU-323's bandwidth to 128 Kbps, 80 is the service prefix
of the first gateway, 7654321 is the phone number of the remote gateway, 4444 is the
extension of the remote VIU-323 and 10 changes the receiving VIU-323's bandwidth to
128 Kbps.
Note: The dialing suffix (when used) must match the dialing prefix (when used); for
example, when the prefix is #20, the suffix, if necessary, must be 20; when the prefix
is #00, the suffix, if necessary, must be 00.
