Getting started with the ISDN gateway
Ensure you have correctly completed the physical setup of the ISDN gateway following the instructions
contained in the Getting Started Guide for the unit. You must also ensure that your endpoints and MCU
are correctly configured to operate with the ISDN gateway.
Before you can make calls using the ISDN gateway, you need to complete the setup of the unit using the
web interface as follows:
1.
Log into the ISDN gateway
: Use your browser to navigate to the IP address of the ISDN
gateway. Click
Change log in
and enter the user name 'admin' with no password. We
recommend that you change the admin user account to use a password as soon as possible.
2.
Set up the ISDN interfaces
:
a. Go to
Settings > ISDN
.
b. Select the
ISDN interface type
to match that of your installation: E1 is typically used in the
UK and mainline Europe, and T1 in North America. Use T1 (Japan) in Japan.
c. You may need to set other advanced ISDN settings. Only change these settings if you
know of a specific requirement to do so.
d. Click
Apply changes
.
e. If you made any changes on this page, you must restart the ISDN gateway before they
will take effect. Go to
Settings > Shutdown
and click
Shut down ISDN GW
.
3.
Configure ISDN ports
: Go to
Settings > ISDN ports
:
a. Set low and high channels:
•
If you have a fully-populated PRI (this is the normal case) set
Low
channel
to '1'
for all network types and
High
channel
to
Max
.
•
If you have a fractional PRI, where your provider offers a reduced number of B-
channels, enter alternative values as appropriate.
b. Set the
Channel search order
: When making calls, the ISDN gateway examines which B-
channels are free before placing a call. This search can be performed starting with the
high channel and working down, or starting with the low channel and working up. Your
ISDN provider will be able to advise which scheme to use, but the choice is not critical.
c. Click
Apply changes
and then, if required, repeat the above steps to configure further
ISDN ports. Select which port you wish to configure using the numbered links at the top
right of the page.
4.
Configure the dial plan
: The default behavior of the unit is to reject all calls. You must configure
a dial plan to allow permitted calls to be placed. The simplest configuration is to create a dial plan
that will connect any 'IP to ISDN' call that has been routed to the ISDN gateway to the number
that the caller has dialed (using any free enabled port) and that will connect any 'ISDN to IP' call
to the auto attendant of your MCU:
a. Go to
Dial plan > IP to ISDN
and click
Add rule
.
b. For
Rule
name
, type in a name for the new rule.
c. For
Condition
, select
Match
any
called
number
.
d. For
Action
, select
Call
with
the
original
called
number
.
e. Leave the other values unchanged. Click
Add rule
to add the rule to the dial plan.
