Enhanced Cisco 810 Series Voice Features for Japan
The enhanced voice features described here are for the Japanese market only.
The first six features achieve PBX-like functionality within Cisco 811 and 813 routers. These routers
support two plain old telephone service (POTS) ports. The PBX functionality is in and between these
two ports.
The remaining features provide capability for silent fax calls, and support for the Personal Handy-Phone
System (PHS) Internet Access Forum Standard (PIAFS).
Intercom
This feature establishes a voice connection between the two POTS ports within the router. No B channels
are used for calling between ports, so the B channels are available for data calls. During an intercom call,
call waiting is disabled. If an external call comes to either POTS port, no call waiting tone is generated.
The calling party will hear a busy signal. Flashhook, DTMF keys and FLASHKEY are also disabled.
An intercom call is established by pressing **0# on the handset of either POTS port. If either port is busy
with an external voice call, the intercom call will not be established.
Redial
This feature allows the user on each POTS port to redial the last number dialed on that port. Redial is
activated when the user presses **4# on the handset. The router will store a number of up to 65 digits
for each port. Feature access codes starting with an asterisk (*), interactive voice response (IVR) digits,
or the pound (#) key are not stored.
The redial feature is supported separately on each POTS port.
Local Call Transfer
An external call received on either POTS port can be transferred to the other port. The transfer is initiated
with a flashhook press followed by pressing **0# on the handset.
This feature does not support conference calls.
Volume Adjustment
This feature allows the adjustment of the receiver volume on each POTS port. Volume adjustment is
configured by CLI commands, separately for each port.
To configure the telephone receiver volume on each port, use the IOS volume command in the dial-peer
configuration mode:
volume number
where number is a numeric value from 1 to 5 representing the volume setting ranging from -12 to 0
decibels (dB). The default setting is 3.
The following example configures the volume of the receiver on the router telephone ports 1 and 2:
router# configure terminal
router(config)# dial-peer voice 1 pots
router(config-dial-peer)# volume 4
router(config-dial-peer)# dial-peer voice 2 pots
router(config-dial-peer)# volume 2
The following is an example of the volume adjustment configuration output from the show
running-config command:
