Example
#00 80 7654321*7654322
Where #00 is the dialing prefix, 80 is the gateway service prefix, 7654321 is the phone
number of the first channel of the unit you are calling, * is the 2nd number delimiter, and
7654322 is the phone number of the second channel.
or dial:
#00 80 7654321*2
Where the delimiter * is followed by the digits of the second number that differ from the
first number dialed, in this case the number 2.
Dialing Through a Gateway and IMUX
When you are calling through a gateway and an IMUX to a unit that has a different
bandwidth, dial:
!
The dialing prefix, followed by
!
The gateway's service prefix, followed by
!
The IMUX profile, followed by
!
The phone number of the receiving unit; if this is a 2x64 Kbps call, this will be
!
The first channel phone number, followed by
!
The 2nd number delimiter.
!
If the second channel phone number is different from the first, you dial the digits
of that number that differ from the first number after the 2nd number delimiter. If
it's the same as the first, don't dial it.
Example
The calling VIU-323 is set to 384 Kbps but the receiving unit is set at 128 Kbps; dial:
#10 80 #001 7654321
Where #10 is the prefix that sets the bandwidth to 128 Kbps, 80 is the gateway service
prefix, #001 is the IMUX profile, and 7654321 is the phone number of the remote unit.
Changing Incoming Bandwidth
When making calls between two VIU-323s, you can force the VIU-323 receiving the call to
change its default bandwidth to match the bandwidth of the VIU-323 making the call.
To do this, add a dialing suffix after the phone number of the remote VIU-323. Dialing
suffixes are for non-restricted bandwidths only and are described in the following table:
