Use the noform of this command in order to delete the translation rule. Issue the voice translation-rulecommand in global configuration mode in order to define a translation rule for voice calls. If an incoming H.323/SIP call is associated with a Source IP Group with a translation profile defined, then the translation profile of the Source IP Group overrides the global translation profile for incoming VoIP calls. VoIP Incoming-The translation profile can be defined globally for all incoming VoIP (h323/sip) calls in order to perform number translation. This translation profile has a higher precedence than the translation profile of a voice port and trunk group in case a channel also belongs to a voice port and/or trunk group with the translation profile defined. Non-Facility Associated Signaling (NFAS) Interface-The translation profile can be defined for an NFAS interface through the translation-profilecommand line from the global voice service potsconfiguration in order to perform the number translation for incoming and outgoing NFAS calls. If a voice port is also a trunk group member, then the incoming translation profile of a voice port overrides the translation profile of a trunk group. Voice Port-The translation profile can be defined in a voice port in order to perform number translation for incoming and outgoing POTS calls. Source IP Group-A translation profile can be defined in a source IP group in order to perform number translation for incoming VoIP calls.ĭial Peer-Two different translation profiles can be defined in a dial peer in order to perform number translation for incoming and outgoing calls. If an outgoing translation profile is defined in a trunk group, the number translation is done while the outgoing call is setup. Trunk Group-Two different translation profiles can be defined in a trunk group in order to perform number translation for incoming and outgoing POTS calls. Once a translation profile is defined, it can be referenced by: You can define these types of call numbers in a translation profile:Įach type of call number in the profile can have different translation rules. New translation rules can be referenced by a translation profile. Only registered Cisco users can access internal Cisco tools and information. Note: Use the Command Lookup Tool to find more information on the commands used in this document. This section presents you with the information used to configure the features described in this document. Up to 128 translation rules can be defined. Up to 1000 translation profiles can be defined. Up to fifteen translation rules can be defined per translation rule table. The keywords NULL and ANY are not supported in new translation rules, but these keywords can be replaced by regular expressions similar to SED. New translation rules come after regular expression that match in a way similar to SED:Īn escape sequence similar to UNIX via backslashes is supported. These rules are specified with a special keyword called 'reject'. Another ability of the translation rules is the ability to block calls on specific numbers. The SED utility is used to check for a match based on the match pattern. The translation rules replace a sub string of the input number if the number matches the match pattern, number plan, and type present in the rule. This document describes highlighted features and configurations for new Voice Translation Profiles and specific examples for the most common scenarios. See the "Related Information" section for more information on SED. The Stream EDitor (SED) utility is used to translate numbers. Central to the new scheme is the ability to perform regular expression matches and replace sub strings. If you mix the old and new schemes, you can have unforeseen results. Cisco strongly recommends you only use one scheme of translation rules. The older translation rules are to be gradually phased out of the system. Voice Translation Profiles introduce a new scheme to translate numbers. Refer to the Cisco Technical Tips Conventionsfor more information on document conventions. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. The information in this document is based on the Voice Gateways that run Cisco IOS®Software Release 12.2(11)T or later. There are no specific requirements for this document. This document describes how to configure number translation with the Voice Translation Profiles.
