The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco Expressway Series (Expressway) is designed specifically for comprehensive collaboration services. It features established firewall-traversal technology and helps to redefine traditional enterprise collaboration boundaries, to support our Cisco vision of any-to-any collaboration.
Expressway offers the following primary features and benefits:
A typical Expressway system is deployed as a pair: an Expressway-C with a trunk and line-side connection to Unified CM, and an Expressway-E deployed in the DMZ and configured with a traversal zone to an Expressway-C.
Expressway is available on a dedicated physical appliance such as a CE12100, or as a virtual machine (VM) on a Cisco UCS server.
Each Expressway can be configured as one of two types, which offer different capabilities.
Expressway-C delivers any-to-any enterprise wide conference and session management and interworking capabilities. It extends the reach of telepresence conferences by enabling interworking between Session Initiation Protocol (SIP)- and H.323-compliant endpoints, interworking with third-party endpoints; it integrates with Unified CM and supports third-party IP private branch exchange (IP PBX) solutions. Expressway-C implements the tools required for creative session management, including definition of aspects such as routing, dial plans, and bandwidth usage, while allowing organizations to define call-management applications, customized to their requirements.
The Expressway-E deployed with the Expressway-C enables smooth video communications easily and securely outside the enterprise. It enables business-to-business video collaboration, improves the productivity of remote and home-based workers, and enables service providers to provide video communications to customers. The application performs securely through standards-based and secure firewall traversal for all SIP and H.323 devices. As a result, organizations benefit from increased employee productivity and enhanced communication with partners and customers.
It uses an intelligent framework that allows endpoints behind firewalls to discover paths through which they can pass media, verify peer-to-peer connectivity through each of these paths, and then select the optimum media connection path, eliminating the need to reconfigure enterprise firewalls.
The Expressway-E is built for high reliability and scalability, supporting multivendor firewalls, and it can traverse any number of firewalls regardless of SIP or H.323 protocol.
Standard features on Expressway include the following:
Cisco does not support the installation of any additional Cisco or third-party software, applications, or agents on Expressway (VMs or physical appliances), unless we state explicitly otherwise. Non-Expressway products may corrupt the Expressway code and must not be installed.
Expressway supports on-premises and cloud applications and is available as a dedicated appliance or as a virtualized application on VMware, with additional support for Cisco Unified Computing System (Cisco UCS) platforms.
Expressway has these virtualized application deployment types:
See Cisco Expressway Virtual Machine Installation Guide on the Expressway Installation Guides page.
The Expressway is also available as a dedicated CE Series appliance based on UCS hardware. For example, the CE1200 appliance based on a UCS C220 M5L, operates as a medium capacity or large capacity Expressway.
The Cisco VCS series is not supported on CE1200 appliances.
Changing the default system size
For appliances deployed as Expressway-E you can manually change the default system size of appliances from Large to Medium, or the other way round. This capability was introduced to mitigate an issue with demultiplexing ports for media traversal on appliances with a 1 Gbps NIC (SFP module) that are configured as Medium systems.
To change the size of the appliance, go to System > Administration settings page and select the required size from the Deployment Configuration list.
See Cisco Expressway CE1200 Appliance Installation Guide on the Expressway Installation Guides page.
If you upgrade a Medium appliance with a 1 Gbps NIC to X8.10 or later, Expressway / Cisco VCS automatically converts the system to a Large system. This means that Expressway-E / Cisco VCS Expressway listens for multiplexed RTP/RTCP traffic on the default demultiplexing ports for Large systems (36000 to 36011) and not on the demultiplexing ports configured for Medium systems. In this case, the Expressway-E / Cisco VCS Expressway drops the calls because ports 36000 to 36011 are not open on the firewall.
From X8.11.4 you can manually change the system size back to Medium, through the System > Administration settings page (select Medium from the Deployment Configuration list).
Before X8.11.4, the workaround is to open the default demultiplexing ports for Large systems on the firewall.
This guide describes the various features, services, and capabilities of Expressway. It assumes a fully equipped version of Expressway, so your deployment may not support all of the items described.
The guide only applies to the Cisco Expressway Series product. For information about Cisco VCS, please refer to the X12.5.x Cisco VCS Administrator Guide on the Cisco TelePresence Video Communication Server Maintain and Operate Guides page.
Most configuration tasks on Expressway can be done through the web user interface or the command line interface (CLI). The guide mainly describes how to use the web user interface. Some features are only available through the CLI, and these are described where relevant.
