Making Calls with the VIU-323
Example
80 #001 7654321*
Where 80 is the gateway service prefix, #001 is the IMUX profile, 7654321 is the phone
number for both the first and second channels of the unit you are calling and * is the 2nd
number delimiter. (You don't have to dial the phone number twice because the phone
numbers are the same for both channels.)
Dialing Through Two Gateways to a Remote LAN Endpoint
When you are dialing through a second gateway to an H.323 endpoint on a remote LAN, if:
!
You are making a BRI call, and
!
The default bandwidth of the calling VIU-323 is 2x64 Kbps, and
!
The default bandwidth of the receiving unit is also 2x64,
then you don't have to change the bandwidth. You must, however, dial:
!
The gateway's service prefix, followed by
!
The remote gateway's phone number; then
!
When you are prompted by an IVR message (for example), dial the extension of the
remote endpoint followed by a hash mark
Example
80 7654321 (IVR prompt) 6666 #
Where 80 is the gateway service prefix, 7654321 is the phone number of the second
gateway, and 6666 is the extension of the remote unit.
Note: Since it is not common that the default outgoing bandwidth of a VIU-323 is 2x64
Kbps, you will probably have to change the outgoing bandwidth. Similarly, it is also
uncommon that the bandwidth of an H.323 device is 2x64 Kbps, so you will probably
have to change the incoming bandwidth.
Changing Outgoing Bandwidth
When you make a call, it is transmitted from the calling VIU-323 at the default outgoing
bandwidth, which is set during VIU-323 configuration; however, if the endpoint you are
calling is set to a different bandwidth, or if you must go through a gateway which requires a
different bandwidth, you can change the default bandwidth of the calling VIU-323 by
adding a prefix to the dialing stream.
