IntroductionService Providers today, such as Spectrum Enterprise1, are offering alternative methods toconnect to the PSTN via their IP networks. Most of these services utilize SIP as the primarysignaling method and centralized IP to TDM POP gateways to provide on-net and off-netservices.A demarcation device between these services and customer owned services is recommended.As an intermediary device between Cisco Unified Communications Manager and Spectrumnetwork, Cisco Unified Border Element (CUBE) ISR 4321/K9 running IOS 16.x can be used.The Cisco Unified Border Element 12.0.0 provides demarcation, security, interworking andsession control services for Cisco Unified Communications Manager 12.0.x connected toSpectrum network.This document assumes the reader is knowledgeable with the terminology and configuration ofCisco UCM (Cisco Unified Communications Manager). Only configuration settings specificallyrequired for Spectrum Enterprise interoperability are presented. Feature configuration and mostimportantly the dial plan are customer specific and need individual approach. This application note describes how to configure a Cisco Unified CommunicationsManager (CUCM) 12.0.x and Cisco Unified Border Element (CUBE) on ISR 4321/K9 [IOSXE – 16.6.1] for connectivity to Spectrum Enterprise SIP Trunking services. Thedeployment model covered in this application note is CPE (CUCM 12.0.x) to PSTN(Spectrum Enterprise). Testing was performed in accordance to Spectrum Enterprise generic SIP Trunking testmethodology and among features verified were – basic calls, DTMF transport, Music onHold (MOH), unattended and attended transfers, call forward, conferences andinteroperability with Cisco Unity Connection (CUC). The Cisco UCM configuration detailed in this document is based on a lab environmentwith a simple dial-plan used to ensure proper interoperability between SpectrumEnterprise SIP Trunking Service(s) and Cisco Unified Communications. The configurationdescribed in this document details the important configuration settings to have enabled forinteroperability to be successful and care must be taken by the network administratordeploying Cisco UCM to interoperate to Spectrum Enterprise SIP Trunking services.This application note does not cover the use of Calling Search Spaces (CSS) or partitions onCisco UCM.

Call FlowIn the sample configuration presented here, Cisco UCM is provisioned with four-digit directorynumbers corresponding to the last four DID digits. No digit manipulation is performed on the CiscoUBE.For incoming PSTN calls, the Cisco UBE presents the full ten-digit DID number to Cisco UCM.The Cisco UCM picks up the last 4 significant Digits configured under SIP Trunk and routes thecall based on those 4 digits. Voice calls are routed to IP phones; Fax calls are routed via a 4-digitroute pattern over a SIP trunk that terminates on the Fax Gateway and in turn to the VentaFaxclient connected to the Fax Gateway.CPE callers make outbound PSTN calls by dialing a “5” prefix followed by the destination number.For outbound fax calls from the analog fax endpoint, Cisco fax Gateway sends to Cisco UCM theDID with leading access code “5”. A “5.@” route pattern strips the prefix and routes the call withthe remaining digits via a SIP trunk terminating on the Cisco UBE for Voice call or Fax. For PBXto PBX via Spectrum Enterprise, Caller dial 5 prefix followed by the target 1 10Digit DID for thatextension number, 5 was stripped and the 1 10 digits number was send to Cisco UBE, CiscoUBE sends the full 1 10 digits DID under Dial Peer 20 to Spectrum network which will direct backto Cisco UBE and handled same as normal incoming PSTN call. For International calls samepattern 5 followed by 011, country code and calling number is used.Figure 3: Outbound Voice CallDial Peer 40YYYYCisco XXXXYYYYSpectrumCUCMCUBEFigure 4: Inbound Voice Call 2016 Cisco Systems, Inc.
