Important notices, privacy statements, and trademarks of Cisco Systems, Inc. can be found on cisco.com Page 4 of 48 Introduction Service Providers today, such as CableOne, are offering alternative methods to connect to the PSTN via their IP network. Most of these services utilize SIP as the primary signaling method and centralized IP to TDM POP gateways to provide on-net and off-net services. CableOne is a service provider offering that allows connection to the PSTN and may offer the end customer a viable alternative to traditional PSTN connectivity. A demarcation device between these services and customer owned services is recommended. As an intermediary device between Cisco Unified Communications Manager (Cisco UCM) and CableOne network, Cisco Unified Border Element (Cisco UBE) ISR 4331/K9 running IOS 16.07.01 can be used. The Cisco Unified Border Element 16.07.01 provides demarcation, security, interworking and session control services for Cisco Unified Communications Manager 11.5.1 connected to CableOne IP network. This document assumes the reader is knowledgeable with the terminology and configuration of Cisco Unified Communications Manager. Only configuration settings specifically required for CableOne interoperability are presented. Feature configuration and most importantly the dial plan are customer specific and need individual approach.  This application note describes how to configure Cisco UCM 11.5.1, and Cisco UBE on ISR 4331/K9 [IOS – 16.07.01] for connectivity to CableOne SIP Trunking service. The deployment model covered in this application note is CPE (Cisco UCM) to PSTN (CableOne) via Cisco UBE v12.0 [IOS-XE] 16.07.01.  Testing was performed in accordance to CableOne generic SIP Trunking test methodology and among features verified were – basic calls, DTMF transport, Music on Hold (MOH), unattended and attended transfers, call forward, conferences and High Availability.  The Cisco UBE configuration detailed in this document is based on a lab environment with a simple dial-plan used to ensure proper interoperability between CableOne SIP network and Cisco Unified Communications. The configuration described in this document details the important configuration settings to have enabled for interoperability to be successful and care must be taken by the network administrator deploying Cisco UCM to interoperate to CableOne SIP Trunking network.

Cisco UCM has a trunk configured to Cisco UBE’s Virtual IP Address. CableOne was used as the service provider with SIP trunk to the Cisco UBE using the WAN Virtual IP Address.  2 Cisco Unified Border Elements are used here for High Availability.  SIP Trunk transport type used between Cisco UBE and Cisco UCM is TCP and to CableOne is UDP.

Most of these services utilize SIP as the primary signaling method and centralized IP to TDM POP gateways to provide on-net and off-net services. Sparklight is a service provider offering that allows connection to the PSTN and may offer the end customer a viable alternative to traditional PSTN connectivity. A demarcation device between these services and customer owned services is recommended. As an intermediary device between Cisco Unified Communications Manager (Cisco UCM) and Sparklight network, Cisco Unified Border Element (CUBE) ISR 4331/K9 running IOS-XE 16.12.02 can be used. The Cisco Unified Border Element v12.7.0 provides demarcation, security, interworking and session control services for Cisco Unified Communications Manager (CUCM) 12.5.1 connected to Sparklight IP network. This document assumes the reader is knowledgeable with the terminology and configuration of Cisco Unified Communications Manager. Only configuration settings specifically required for Sparklight interoperability are presented. Feature configuration and most importantly the dial plan are customer specific and need individual approach. • This application note describes how to configure Cisco UCM 12.5.1, and Cisco UBE on ISR 4331/K9 [IOS-XE – 16.12.02] for connectivity to Sparklight SIP Trunking service. The deployment model covered in this application note is CPE (Cisco UCM) to PSTN (Sparklight) via Cisco UBE v12.7.0 [IOS- XE] 16.12.02. • Testing was performed in accordance to Sparklight generic SIP Trunking test methodology and among features verified were – basic calls, DTMF transport, Music on Hold (MOH), unattended and attended transfers, call forward, conferences and High Availability. • The Cisco UBE configuration detailed in this document is based on a lab environment with a simple dial-plan used to ensure proper interoperability between Sparklight SIP network and Cisco Unified Communications. The configuration described in this document details the important configuration settings to have enabled for interoperability to be successful and care must be taken by the network administrator deploying Cisco UCM to interoperate to Sparklight SIP Trunking network.

Cisco UCM has a trunk configured to Cisco UBE’s Virtual IP Address. Sparklight was used as the service provider with SIP trunk to the Cisco UBE using the WAN Virtual IP Address. • 2 Cisco Unified Border Elements are used here for High Availability. • SIP Trunk transport type used between Cisco Unified Border Element and Cisco UCM is TCP and to Sparklight is UDP.
