Configuring E&M Voice Ports
To configure E&M voice ports, use the following commands beginning in global configuration mode:
Step 4
Router(config-dial-peer)# session target
Assigns the session target for voice multicasting
dial peers. This is a multicast address in the range
of from 224.0.1.0 to 239.255.255.255 and must be
the same for all ports in a session.
The audio RTP port is an even number in the range
of from 16384 to 32767 and must also be the same
for all ports in a session. An odd-numbered port
(UDP port number + 1) is used for the RTCP traffic
for that session.
Step 5
Router(config-dial-peer)# ip precedence number
(Optional) Specifies the IP precedence.
Step 6
Router(config-dial-peer)# codec
Configures the codec. You must configure the same
codec on all dial peers in a session.
When the default codec g729r8 is used, it does not
appear in the configuration when the show
running-config command is used.
Command Purpose
Command Purpose
Step 1
Router(config)# voice class permanent tag
Defines voice class for transmit-receive mode.
Step 2
Router(config-class)# signal timing oos timeout
seconds disabled
Disables signaling loss detection. (Use the
disabled keyword in hoot and holler applications.
The seconds argument is not used in these
applications.)
Step 3
Router(config-class)# signal keepalive number
Specifies the keepalive signaling packet interval.
Step 4
Router(config-class)# exit
Exits voice-class configuration mode.
Step 5
Router(config)# voice-port
{slot-number/subunit-number/port} |
{slot/port:ds0-group-no}
Enters voice-port configuration mode and selects
the voice port to configure.
Step 6
Router(config-voice-port)# voice-class permanent tag
Assigns a previously configured voice class for a
Cisco trunk or FRF.11 trunk to a voice port (for the
port that is allowed to speak).
Step 7
Router(config-voice-port)# connection {plar | tie-line
| plar-opx} digits | {trunk digits [answer-mode]}
Ties the voice port to a multicast-session number.
Use the trunk keyword to specify a connection that
emulates a permanent trunk connection to a PBX.
The digits argument specifies the destination
telephone number. Valid entries are any series of
digits that specify the E.164 telephone number.
Step 8
Router(config-voice-port)# music-threshold number
(Optional) Sets the music threshold to make
voice-activated dialing (VAD) less sensitive. The
number argument is the on-hold music threshold in
decibels (dB). Valid entries are any integer from
-70 to -30.
