the call needs to go on the SCN, the server will redirect it to
a proper analog gateway (such as the AT-VP504E FXO) that
will place the call to the SCN network.
X To dial a Forced SCN call:
1. Dial “**”.
2. Dial the telephone number as if you were using a standard
telephone, with country code and Area Code when required.
Examples:
**829-8749
**1-514-570-1234
A Forced SCN Call allows you to specify that the user you
want to reach is located on the SCN network. This leaves no
decisions to the server; it must find a proper gateway and
place the call on the SCN. This option can be useful only
when a SCN number is shadowed by a network number. This
type of call should not be used often.
Dialing an IP
Address
You can dial another AT-VP504E FXS without the help of the IP
Communication Server by entering its IP address. You will only be able
to reach the phone or fax connected to Port 1 of this AT-VP504E FXS
This procedure will only work if your AT-VP504E FXS is running the
SIP signalling protocol. See your network administrator for more
details.
X To dial an IP address:
1. Dial “***”.
2. Dial the numerical digits of the IP address and use “*” for the
“.” of the IP address.
3. Dial “#” to terminate the IP address.
For example, to dial 192.168.0.23, the user dials the following
digits:
Note: You can dial one star numbers *xx (such as *69). These
numbers will be automatically inserted in the Request-URL of the SIP
INVITE request.
Note: A forced SCN call will only be possible if an analog gateway
such as the AT-VP504E FXO is available on the IP network.
