Access the second EXTender 7000 and set the Gateway Port Offset. For example, if you have eight
EXTended phones on the first remote set the Gateway Port Offset to 8. This indicates to the second
remote to use ports 9-16 on the Gateway.

Use the MCK Bandwidth Calculator to compute the number of local calls in this 2 to 1 configuration.
5.
When the calculator computes the number of local calls that can be made from your extended tele-
phones, simply remember that this number represents the number of local calls that can be made by
BOTH
remote units.
De-hairpinned Calls
When a Local Call is made, once it has been established, it will become Hairpinned (status is shown as "H"
on the UI). When the user presses a PBX feature key, the call becomes de-hairpinned (status changes to
“D”) and is directly connected to the PBX. Each de-hairpinned call will use some bandwidth.
Use the MCK Bandwidth Calculator to determine how many "Possible Calls That Can Access PBX Fea-
tures" for this 2 to 1 configuration. When the calculator computes the number of "Possible Calls that Can
Access PBX Features", simply remember that this number represents "Possible Calls That Can Access
PBX Features" shared by BOTH remote units.
Example:
For example, if the possible number of de-Hairpinned calls is 6, the first EXTender 7000 could allow 4 de-
Hairpinned calls, while the second EXTender 7000 could allow only 2 de-Hairpinned calls.
Example:
For example, if the possible number of Hairpinned calls is 6, the first EXTender 7000 could allow 4 Hair-
pinned calls, while the second EXTender 7000 could allow only 2.
Note, the maximum number of
Hairpinned calls is unlimited, de-hairpinned calls is limited to 12 when using RVPoIP
.
