© 2023 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information
for any outbound call. If all outbound
calls that use the hookflash functionality
are on the same server, it is
recommended to use the param dial-
peer command.
When multiple matches are possible on
hookflash, enable peer parameters
callXXXX TRUE for DSAPP to interpret
hookflash to SIP supplementary service
Example:
Router(config)#application router(config-
app)#service dsapp
Router(app-global)#param dialpeer 100
Router(app-global)#param callWaiting TRUE
Enables call waiting feature.
param callConference string
Enables call conference feature.
param callTransfer string
Example:
Router(config)#application router(config-
app)#service dsapp
Router(app-global)#param dialpeer 100
Router(app-global)#param callWaiting TRUE
Router(app-global)#param callConference TRUE
Router(app-global)#param callTransfer TRUE
Enables call transfer feature.
Configuring the Outbound VoIP Dial-peer
Outbound dial-peer is configured like regular voip dial-peer for SIP. In addition to the parameters
required, the following configurations are required:
• service dsapp– specifies this dial-peer will be controlled by dsapp application
• session transport tcp – specifies only TCP signaling is supported now
• voice-class sip extension gw-ana – used to interop with CUCM
• voice-class sip bind control source-interface GigabitEthernet0/0/1 – need this interface’s mac
as the base mac
