APPENDIX D: IOS Dial-peer configuration via CLI
APPENDIX D: IOS Dial-peer configuration via CLI
Introduction:
This appendix goes over a feature in the UC520 software (IOS) called dial peers which are the core for
routing calls out the IP network (VoIP) or TDM interfaces (POTS) such as FXO, T1 / E1 PRI on the
UC520. Essentially the dial-peers in the configuration define the dial plan for calls going through the
UC520. The appendix will introduce this concept of dial-peers and some basics.
NOTE: In general, dialplan customization should be done through the CCA. This is section is
intended only as a reference to users who have a high degree of IOS and CLI experience. If IOS
CLI must be used, please make sure to follow the Out-of-Band Configuration Guidelines posted
below:

Objective:
The default configuration on the UC520 as well as Cisco Configuration Assistant (CCA) does leverage
dial-peers for a lot of the call routing / dial plan functionality. The objective is to show what the dial-
peer CLI pushed down means to a certain extent. It will also go over a couple of examples of using dial-
peers such as for least cost routing or translating digit strings. All configurations will be done using the
command line interface (CLI). After completion of this lab – you should have a simplistic overview of
dialplan and call routing in UC520 / SBCS.
