Step 4
Router(config-voiceport)# ring frequency {25 | 50}
(FXS only) Selects the ring frequency, in hertz
(HZ), used on the FXS interface. This number must
match the connected telephony equipment and may
be country-dependent. If not set properly, the
attached telephony device may not ring or it may
buzz.
The keyword default is 25 on Cisco 2600 series,
Cisco 3640 and Cisco 3660 routers.
Step 5
Router(config-voiceport)# ring number number
(FXO only) Specifies the maximum number of
rings to be detected before an incoming call is
answered by the router.
The default is 1.
Step 6
Router(config-voiceport)# ring cadence {[pattern01 |
pattern02 | pattern03 | pattern04 | pattern05 |
pattern06 | pattern07 | pattern08 | pattern09 |
pattern10 | pattern11 | pattern12] | [define pulse
interval]}
(FXS only) Specifies an existing pattern for ring, or
defines a new one. Each pattern specifies a
ring-pulse time and a ring-interval time. The
keywords and arguments are as follows:
• pattern01 through pattern12 name pre-set
ring cadence patterns. Enter ring cadence ? to
see ring pattern explanations.
• define pulse interval specifies a user-defined
pattern: pulse is a number (one or two digits,
from 1 to 50) specifying ring pulse (on) time in
hundreds of milliseconds, and interval is a
number (one or two digits from 1 to 50)
specifying ring interval (off) time in hundreds
of milliseconds.
The default is the pattern specified by the cptone
locale that has been configured.
Step 7
Router(config-voiceport)# description string
Attaches a text string to the configuration that
describes the connection for this voice port. This
description appears in various displays and is
useful for tracking the purpose or use of the voice
port. The string argument is a character string from
1 to 255 characters in length.
The default is that there is no text string (describing
the voice port) attached to the configuration.
Step 8
Router(config-voiceport)# no shutdown
Activates the voice port. If a voice port is not being
used, shut the voice port down with the shutdown
command.
