1 Audience 

This document is intended for the SIP trunk customer’s technical staff and Value Added Retailer (VAR) 

having installation and operational responsibilities. 

2 Introduction 

This Configuration Guide describes configuration steps for Cox SIP trunking to a Cisco UC-520 PBX. Cox 

SIP trunking is a scalable and efficient IP trunking telecommunication solution for your business that 

provides all the traditional services such as Direct Inward Dialing, Hunting, Calling Name, Calling Number, 

Local/Long Distance and Business Continuity options, including: 

Burstable Trunk Capacity – Dynamically increases call capacity during peak busy periods so your 

customers never receive a busy signal. 

Call Forward Always – On the trunk group pilot number for all calls in case of an outage (i.e., 

flood, fire, loss of power, etc.). 

Call Forward Not Reachable – On the trunk group pilot number that operates on a per-call 

contingency basis to forward the call to any PSTN number (i.e., call center or alternate office 

location) during temporary call completion impairments. 

Route Exhaustion – Automatic reroute of trunk group calls to any PSTN phone number (i.e., a call 

center) if calls can’t be completed to the PBX. 

Support for geo-redundant PBX deployments and automatic reroute of SIP trunks to the backup 

customer data center. 

All calls are routed over Cox’s national fiber network with guaranteed Quality of Service (QoS); calls never 

traverse the Internet.

3 SIP Trunking Network Components 

The network for the SIP trunk reference configuration is illustrated below and is representative of a Cisco 

UC-520 PBX configuration. 

Figure 2 - SIP Trunk Lab Refernce Network 

Note: The UC520 PBX provides the DHCP server for dynamic IP address assignment for the SIP phones; 

however, the Cox Enterprise Session Border Controller (E-SBC) requires a static LAN IP address that 

must be manually assigned by the LAN network administrator. This is accomplished in the UC520 

configuration by constraining the DHCP IP address range and assigning an IP address outside of the 

DHCP pool. 

The lab network consists of the following components: 

UC520 PBX for voice features, DHCP, routing, firewall, SIP proxy and SIP trunk termination. 

Various SIP phones on the local LAN. 

The Cox E-SBC is the Edgewater Networks (www.edgewaternetworks.com) EdgeMarc appliance. 

The EdgeMarc is the service demarcation point between customer’s LAN network and Cox’s 

WAN network and provides firewall/NAT traversal, B2BUA and SIP Application-level gateway. 

The EdgeMarc has diverse routes to a primary and secondary Acme SBC. 

Acme Packet Net-Net 9200 Session Border Controllers (SBC).

4 Features 

4.1 SIP Registration Method 

Cox Network requires support for SIP REGISTER. This will allow the IP-PBX to call from and to the 

network. The Cisco UC520 supports SIP Register with authentication. Cox implementation team provides 

the Pilot number and the authentication key, which should be provisioned in the UC520. How to configure 

these in the UC520 are shown in section 6.3.5 

4.2 Features Supported 

Basic calls using G.711ulaw 

Calling Party Number Presentation and Restriction 

Call Transfer 

Call Forwarding 

RFC2833 transcoding 

Fax and modem inband G.711 

4.3 Features Not Supported 

PBX Account Codes are not supported via Cisco Configuration Assistant (CCA). They may be 

supported by Cisco Command line interface (CLI). For configuration purposes it is recommended 

to only use CCA. 

PBX Authorization Codes are not supported via CCA. They may be supported by Cisco CLI. For 

configuration purposes it is recommended to only use CCA. 

T38 fax is not supported via CCA. T38 fax can be supported via Cisco CLI. For configuration 

purposes it is recommended to only use CCA.

5 Caveats and Limitations 

Cisco UC520 hairpins both call legs during call transfer, meaning the SIP sessions are not 

released after transfer. The sessions are released when the calls are released. 

Cisco UC520 must be configured with “modem passthrough nse code g711ulaw” globally or per 

dial peer in order for the modem tones to work properly, see detail description in section 6.6.1 

Cisco UC520 must have “sip-profiles 1000” removed from “voice service voip sip” once the CCA 

configures the sip trunk in order for voice mail and auto-attendant to work, see detailed 

description in section 6.6.2 

Cisco UC520 must have modem line configured as User Phone in Ports Analog Port Settings in 

the CCA, see detailed description in section 6.3.6
