Introduction
•This application note provides interoperability information and documented configurations for a toll bypass solution using Cisco IOS Voice
Gateways tunneling QSIG over SIP between two Avaya PBXs. The integration consists of two Cisco IOS Voice Gateways connecting to the
Avaya PBXs using T1 QSIG trunks. The IOS gateways establish the QSIG connection between the two PBXs via SIP. Since QSIG is not
dependant of the physical layer interface, this app note applies to both T1 and E1. This integration also demonstrates use of the
Cisco Unified Border Element (CUBE) in the SIP connection between the two Cisco IOS Voice Gateways. Figure 1 shows the integration
topology.
•Interoperability was verified using a single CUBE. In a production deployment, two CUBEs will be required: one at either side of the toll
bypass network. Each CUBE is acting as a point of demarcation between the service provider network and the privately managed networks.
The topology in Figure 1 reflects this deployment. This application note includes a sample CUBE configuration that was used in the
verification with a single CUBE. It can be used as a guide in a production deployment with two CUBEs. The outcome of limitations and
features will not change with a second CUBE in the topology. However, modifications to CUBE and/or IOS Voice Gateway configurations
are necessary to point VoIP dial-peers to the proper session target IP addresses, based upon the implemented dial plan.
•The following basic call and supplementary services features were verified: proper establishing and disconnecting of calls, calling name and
number presentation and restriction, alerting name, call transfer (consult and blind), call forwarding (all, busy, and no reply), callback
functionality, and voicemail access with MWI de/activation. All of the above features are tested with join or reroute schema in both internal
(local) and external network. Please note that this document does not address performance and scalability, which are part of a broader criteria
for a deployment-ready solution.
•This application note uses the C3825 and C3845 IOS-voice-gateway. However other Cisco voice gateways are also an option to use since the
voice gateway implementation does not depend on the platform. Below is a list of Cisco platforms capable of voice gateway functionality
and CUBE functionality: Care must be taken when selecting a voice gateway platform depending on the capacity and capability required
for the intended deployment.
- Cisco 1861 Integrated Services Router
- Cisco IAD2400 Series Integrated Access Device
- Cisco 2800 Series Integrated Services Routers
- Cisco 3700 Series Multi-service Access Routers
- Cisco 3800 Series Integrated Services Routers
- Cisco AS5350XM Universal Gateway
- Cisco AS5400XM Universal Gateway

Limitations
The following section lists known limitations, caveats, or integration issues.
•Call Forwarding by Join, Local and Network/External: The Forwarding called numbers are not displayed on Final Destination phones
and the Final Destination Connected numbers are not updated at the Original side. These are the normal behavior on Avaya digital
display telephones.
•Call Forwarding by Reroute, Network/External: The Original Calling number and the Forwarding Called Name and Number are not
displayed on Final Destination phone. Also, The Final Destination Connected Name and number are not updated at the Original side.
This is the normal behavior on Avaya digital display telephones.
