Configuration Tasks
16
Cisco IOS Release 12.1(5)T
Configuring for Receive Only Mode (Optional)
To configure Cisco Hoot and Holler over IP as receive-only mode, perform the following steps:
Configuring Relevant Interface (Serial/Ethernet) (Required)
To configure either the serial or Ethernet interface, perform the following steps:
Step 11
Router(config-voice-port)# signal { wink-start |
immediate | delay-dial }
Configures the signaling type for E&M voice
ports. The default is wink-start. Select
immediate for the Cisco Hoot and Holler over IP
application. In the immediate-start protocol, the
originating side does not wait for a wink before
sending addressing information. After receiving
addressing digits, the terminating side then goes
off-hook for the duration of the call. The
originating endpoint maintains off-hook for the
duration of the call.
Step 12
Router(config-voice-port)# voice-port
router-slot/voice-slot/VIC-port
Selects another voice port.
Step 13
Router(config-voice-port)# voice-class permanent tag2
Uses voice class tag2 for the receive-only port.
Step 14
Router(config-voice-port)# connection trunk
multicast-session-number
Ties the voice port to the same multicast-session
number as in Step 12.
Step 15
Router(config-voice-port)# music-threshold threshold
(Optional) Sets the music threshold to make VAD
less sensitive.
Step 16
Router(config-voice-port)# operation 4-wire
Specifies 4-wire operation. (2-wire is the default.)
