Introduction
Service Providers today, such as Cox Business, 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 a centralized IP to TDM gateway to provide on-net and off-net services. Cox is a service provider offering that allows connection to the PSTN and may offer the end customer a viable alternative to traditional PSTN connectivity via either analog or T1 lines. A demarcation device between these services and customer owned services is recommended.
· This application note describes how to configure a Cisco Unified Communications Manager Express (Cisco Unified CME) v12.6, Cisco Unity Connection 12.0.1 with connectivity to Cox SIP trunk service. The application note also covers support and configuration example of Cisco Unity Connection (CUC) messaging integrated into the Cisco Unified CME. The deployment model covered in this application note is Customer Premises Equipment (Cisco Unified CME/CUC) to PSTN (Cox). Cox provides inbound and outbound call service.
· Testing was performed in accordance to Cox test plan and all features were verified. Key features verified are: inbound and outbound basic call (including international calls), calling name delivery, calling number and name restriction, CODEC negotiation, intra-site transfers, intra-site conferencing, call hold and resume, call forward (forward all, busy and no answer), leaving and retrieving voicemail (Cisco Unity Connection), Cisco auto-attendant (Cisco Unity Connection), fax using T.38 and G.711.
· Consult your Cisco representative for the correct IOS-XE image and for the specific application and Device Unit License and Feature License requirements for all your Cisco Unified CME.

Network Topology
Figure 1 Network Topology
· The network topology includes the Cisco Unified CME, Unity Voicemail system and 4 Cisco Endpoints. Cisco Unified CME has a trunk configured to Cox IP Address. Cox was used as the service provider with SIP trunk to the Cox eSBC LAN IP Address.
· SIP Trunk transport type used between Cisco Unified CME to Cox eSBC is UDP.
Cisco Unified CME Settings:
Setting Transport from Cisco Unified CME to Cox eSBC Voice Mail Support Session Refresh
