Example
The following example enables the H.450 Tcl script for analog transfer using hookflash and sets a delay
time of 1 second:
call application voice transfer_app flash:app-h450-transfer.tcl
call application voice transfer_app language 1 en
call application voice transfer_app set-location en 0 flash:/prompts
call application voice transfer_app delay-time 1
!
dial-peer voice 25 pots
destination-pattern 9.T
port 1/0/0
application transfer_app
!
dial-peer voice 29 voip
destination-pattern 4…
session-target ipv4:10.1.10.1
application transfer_app
Configuring Trunk Access Codes
Note Configure trunk access codes only if your normal network dial-plan configuration prevents you from
configuring permanent POTS voice dial peers to provide trunk access for use during fallback. If you
already have local PSTN ports configured with the appropriate access codes provided by dial peers (for
example, dial 9 to select an FXO PSTN line), this configuration is not needed.
Trunk access codes provide IP phones with access to the PSTN during Cisco Unified CallManger
fallback by creating POTS voice dial peers that are active during Cisco Unified CallManager fallback
only. These temporary dial peers, which can be matched to voice ports (BRI, E&M, FXO, and PRI),
allow Cisco Unified IP Phones access to trunk lines during Cisco Unified CallManager mode. When
Cisco Unified SRST is active, all PSTN interfaces of the same type are treated as equivalent, and any
port may be selected to place the outgoing PSTN call.
Trunk access codes are created using the access-code command.
SUMMARY STEPS
1. call-manager-fallback
2. access-code {{fxo | e&m} dial-string | {bri | pri} dial-string [direct-inward-dial]}
Step 9
application application-name
Example:
Router(config-dial-peer)# application
transfer_app
Loads the application named in Step 1 onto the dial peer.
Step 10
exit
Example:
Router(config-dial-peer)# exit
Exits dial-peer configuration mode.
Timesaver Before exiting dial-peer configuration mode,
configure any other dial-peer parameters that
you need to set for this dial peer.
