Introduction
Service Providers today, such as Cbeyond, 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. Cbeyond is a SP
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. The Cisco Unified Border
Element provides demarcation, security, interworking and session management services.
This application note describes how to configure a Cisco Unified Communications Manager (CUCM) 10.5 with a Cisco Unified Border
Element (CUBE) for connectivity to Cbeyond SIP trunk service. The deployment model covered in this application note is CPE (CUCM
10.5/CUBE) to PSTN (Cbeyond). This document does not address 911 emergency outbound calls. For 911 feature service
details contact Cbeyond directly.
Testing was performed in accordance to Cbeyond and all features were verified. Key features verified are:
o Basic Calls
o Basic Calls with Calling Name and Number as allowed or restricted
o DTMF Relay
o Call Conference
o Call Transfer (Blind, Attended, Early Attended)
o Hold and Resume
o Voice Mail
o Simultaneous Calls
o Auto Attendant
o International calls
o G.711 FAX G3/SG3
o Call Forwarding - Find Me (Unconditional, Busy, No Reply)
o Dial Plans
o PRACK with SDP early-media cut-through
The Cisco Unified Border Element configuration detailed in this document is based on a lab environment with a simple dial-plan used to
ensure proper interoperability between Cbeyond SIP network and Cisco Unified Communications. The configuration described in this
document details the important commands to have enabled for interoperability to be successful and care must be taken, by the network
administrator deploying CUBE, to ensure these commands are set per each dial-peer requiring to interoperate to Cbeyond SIP network.
This application note does not cover the use of Calling Search Spaces (CSS) or Partitions on Cisco Unified Communications Manager.
To understand and learn how to apply CSS and Partitions refer to the cisco.com link below:

Caveats
• Cbeyond’s network negotiates G.711-µlaw for voice and fax.
• The Cisco IP phones used in the test do not support blind transfer, hence only Semi-Attended and Attended transfer were tested.
• Cbeyond’s network does not allow anonymous caller in FROM header. For Calling ID restriction test, the voice-class sip-profile
command was used in the CUBE to replace FROM header with an assigned DID account. Cbeyond will restrict the caller ID based on the
SIP Privacy Header.
• During CUBE HA test, incoming calls from Cbeyond work correctly while switching between active and standby CUBE, but outgoing
calls to Cbeyond’s network does not work until the newly activate CUBE completes the SIP trunk registration process.

Configuration
Configuring Cisco Unified Border Element (CUBE)
Network Interface and CUBE HA
Configure CUBE High Availability (HA) using HSRP (Hot Standby Router Protocol). Two identical ISR G2s equipped with UC
Technology Package License installed, 1G DRAM memory and Cisco IOS software release 15.1.2t or later are required. Both
routers must be physically located on the same Ethernet LAN. The CUBE configuration of both routers need to be identical except
slight difference in HSRP configuration between the Active and standby routers. In our lab test, Dual-Attached deployment is used
as shown in chapter Network Topology.

SIP trunk registration
With the implementation of SBCs in Cbeyond’s network, a PBX must be capable of sending all SIP messages to an “outbound
proxy” that is independent of the addressing of the target, ie. the “Registrar or SIP Proxy”. For Cbeyond’s interop testing, the
“outbound proxy” is an SBC with FQDN sip-proxy-fca.atl0.cbeyond.net. All requests must be sent to this address. However, this
FQDN should not be populated anywhere in the SIP message being sent. The target URI of Cbeyond’s SIP server, sipconnect-
fca.atl0.cbeyond.net, should be populated in the appropriate headers of the SIP message.
The PBX must be configured with FQDNs rather than IP address for devices on Cbeyond’s network. The PBX must be able to
register to the Cbeyond SIP trunk service.

Media Passing Through CUBE(media flow-through vs. media flow-around)
Default CUBE configuration enables CUBE to work in media flow-through mode (this mode was used in this certification test). In
order to enable flow-around mode, please perform the following actions:

Device Pool
Navigate to System > Device Pool and click on Add New to create the Device Pool. In our test, we created G729 and G711 Device Pools associated with newly added G729 and G711 Regions based on the preferred codecs in the Audio Codec Preference Lists. All SIP/SCCP phones and SIP trunks to VG224 are configured with G711 device pool and the SIP trunk to
CUBE is assigned to G729 device pool.

Off-net calls via Cbeyond’s network
Off-net calls are served by SIP trunks configured between CUCM and SBCs in Cbeyond’s network. Calls are routed via CUBE. SIP Trunk Security Profile
Go to System > Security > SIP Trunk Security Profile and click on Add New. Cbeyond_ Non Secure SIP Trunk Profile is used in
this test.
Figure 20 SIP Trunk Security Profile
Parameter Value Description
Incoming Transport Type TCP + UDP
Outgoing Transport Type UDP SIP trunks to Cbeyond SBC should use UDP as a transport protocol for SIP. This is configured using SIP Trunk Security profile, which is later assigned to the SIP trunk itself.
Incoming Port 5060 5060 is the default fprt for TCP/UDP

SIP Profile
Navigate to Device > Device Settings > SIP Profile and modify default SIP Profile by clicking on a Copy button.
Cbeyond_SIP_PROFILE was created in this test and will be later associated with the SIP trunk.

SIP Profile Cbeyond_SIP_PROFILE SIP Profile configured earlier
DTMF Signaling Method RFC 2833 RFC 2833 is supported for DTMF transport to/from Cbeyond
Reset the trunk after the configuration is completed. Apply same procedure to create SIP trunks to Cisco Analog Gateway VG224.
Dialplan
CUBE translates 10 digits dialed number from Cbeyond’s network to 4 digits extension. Hence there is no need to configure
Translation Pattern under Call Routing. For outgoing call from Cisco CUCM a Route Pattern must be configured. Cisco IP phones
dial 9+10/11 digits PSTN number to access PSTN via CUBE. “9” is removed before being sent to CUBE; the same applies to
outbound fax call from VG224. In order to test calling number privacy, a separate route pattern (679.@) was created to have
Calling Line ID Presentation set to “Restricted”. For incoming fax call to VG224, Route Pattern 2903 is configured.
Navigate to Call Routing > Route/Hunt > Route Pattern and press Add New button to create Route Patterns
