Creating an Outgoing Phone List
For ISDN, V.25bis, and Hayes connections, the router uses the outgoing phone list
to place a call to a remote router. Outgoing phone lists are associated with a
specific circuit, not with the physical line. The lines in the pool can be used by
many circuits, which is why the telephone numbers are part of each circuit’s
configuration and not the line’s configuration.
To create an outgoing phone list, navigate to the backup-circuit prompt and enter:
out-phone-number phone-number
<
string
>
string is a numeric string; maximum of
25 characters. Do not enter space, special,
or alphabetic characters in the telephone number.
For example:
backup-circuit/8/1/1# out-phone-number phone-number 9786665432
You can also include a subaddress/extension to further identify the remote router.
For ISDN calls, this subaddress is useful when there are several routers at a
destination site, but the ISDN provider only assigns the destination one phone
number. An incoming call must specify the number and subaddress to reach a
specific router.
To configure an extension, navigate to the out-phone-number prompt and enter:
subaddress-extension
<
string
>
string is a numeric string; maximum of
25 characters. Do not enter space, special,
or alphabetic characters in the telephone number.
For example:
out-phone-number/backup/8/1/1/9786665432# subaddress-extension 456
For ISDN configurations, go to the next section; otherwise, go to
“Setting Up the Caller Resolution Table
” on page 3-19.
