Cisco Jabber Guest can be deployed in combination with Cisco Expressway-E and Cisco Expressway-C or in combination with Cisco VCS-E and VCS-C. To simplify the documentation, we reference only Cisco Expressway-E and Cisco Expressway-C throughout this guide.
The mobile and web clients use the same interfaces when interacting with Cisco Expressway/Cisco TelePresence Video Communication Server (VCS) and Cisco Jabber Guest. To simplify the documentation, we reference only the web client throughout this guide.
Deploy Cisco Jabber Guest with an existing Cisco Unified Communications Manager installation.
Cisco Unified Communications Manager 8.6.x or later
Cisco Jabber Guest requires that your Cisco Unified Communications Manager be configured to work with Cisco Expressway.
Cisco Jabber Guest Server
Cisco Expressway-C X8.2 or later
Cisco Expressway-E X8.2 or later
Without Cisco Expressway-C and Cisco Expressway-E, you are limited to testing with clients that can directly access the network on which the Cisco Jabber Guest server is homed.
You cannot use the same Cisco Expressway-C and Cisco Expressway-E pair or cluster for both Cisco Jabber Guest and Expressway for Mobile and Remote Access.
For more information, download the Cisco Expressway Administrator Guide, deployment guides, and release notes or see the online help for complete information on configuring the options available on your Cisco Expressway.
Cisco Jabber Guest is deployed as a virtual server using the Open Virtualization Format (OVF) standard for packaging and distributing virtual appliances that run in a virtual environment. It requires VMware vSphere as the hypervisor. Cisco publishes the distribution as an OVF file with the file extension .OVA, which stands for Open Virtual Appliance. This file contains the OVF template for the application. The OVF template defines the virtual machine’s hardware and is preloaded with required software.
A server platform that meets VMware’s Compatibility Guide for VMware vSphere 5.x or later is required. The Cisco Jabber Guest virtual machine uses a 64-bit distribution of CentOS 6.8. Make sure that the server platform uses CPUs that are capable of 64-bit instructions.
Cisco Jabber Guest Server is supported on any Full UC Performance CPU, beginning with Intel Xeon Processor 5600 with a minimum physical core speed of 2.53 GHz or higher and any Restricted UC Performance CPU, beginning with Intel Xeon Processor E5 2609 v1 with a minimum physical core speed of 2.4 GHz or higher. For more information on Full UC performance CPUs and Restricted UC Performance CPUs, see the Processors/CPUs section in UC Virtualization Supported Hardware.
Cisco Jabber Guest is allowed on server models meeting required specifications, including Cisco Business Edition 6000 (BE6000), Cisco Business Edition 7000 (BE7000), and UC on UCS Tested Reference Configurations with a Full UC Performance CPU. BE6000M (M2) UCS C200 M2 TRC#1 is not supported. For more information, see Virtualization for Cisco Jabber Guest Server. Cisco Jabber Guest Server must follow the application co-residency and virtual-to-physical sizing rules in the Unified Communications Virtualization Sizing Guidelines.
Cisco Jabber Guest supports all virtualization software described in Purchasing/Sourcing Options for Required Virtualization Software.
If Cisco Jabber Guest Server is installed on a Cisco Business Edition 6000 server or Cisco Business Edition 7000 server, it must follow the additional co-residency rules in the Cisco Business Edition 6000 and Cisco Business Edition 7000 Co-residency Policy Requirements.
See the VMware developer documentation for additional configuration and hardware requirements. We highly recommend using the Cisco Unified Computing System (CUCS) to simplify and maximize performance.

Cisco Expressway-E with a single NIC—SIP traffic goes to the Cisco Expressway-C and media flows over a port range between the Cisco Expressway-E and the Cisco Expressway-C.
Cisco Expressway-E with dual NIC—SIP traffic goes to the Cisco Expressway-E and media flows through the traversal zone between the Cisco Expressway-E and the Cisco Expressway-C.
Only the Cisco Expressway-E with dual NIC deployment supports NAT/PAT between the Cisco Expressway-E and the Cisco Expressway-C.
Cisco Jabber Guest can be pointed directly to Cisco Unified Communications Manager for lab deployments only; configure a SIP trunk on Cisco Unified Communications Manager for this deployment. This option is best suited to a lab deployment in which the goal is to familiarize yourself with Cisco Jabber Guest without the additional overhead of configuring Expressway. However, without configuring Expressway, Cisco Jabber Guest is not supported in a production environment.
SIP traffic is sent to the Cisco Expressway-C.
Cisco Expressway-E is single NIC only.
Cisco Expressway-E in static NAT mode is optional and requires additional configuration on the Cisco Jabber Guest server.
Cisco Expressway-E is used for TURN services and reverse proxy, not call control.
Media flows between the Cisco Expressway-E and the Cisco Expressway-C over port range, not a traversal zone.
SIP traffic is sent to the Cisco Expressway-E.
Cisco Expressway-E is dual NIC only.
Cisco Expressway-E in static NAT mode is optional and requires additional configuration on the Cisco Jabber Guest server.
Cisco Expressway-E is used for TURN services, reverse proxy, and call control.
Media flows between the Cisco Expressway-E and the Cisco Expressway-C through a traversal zone.
In a production environment, Cisco Jabber Guest requires that your Cisco Unified Communications Manager be configured to work with Cisco Expressway.
![]() Note | If Cisco Expressway-E is used for reverse proxy functionality, the Cisco Jabber Guest URL looks like https://expressway-e.example.com/call where expressway-e.example.com is the FQDN of Cisco Expressway-E. |
The following are examples of call control flow for the two supported deployments of Cisco Jabber Guest Server.
SIP flows between the Cisco Jabber Guest server and the Cisco Expressway-E. This requires bi-directional TCP traffic between the two servers over 5060 (SIP over TCP) or 5061 (SIP over TLS). The SIP traffic then goes over the traversal zone to the Cisco Expressway-C.
We recommend that you disable SIP and H.323 application-level gateways on routers/firewalls carrying network traffic to or from a Cisco Expressway-E.
Because media hairpins between the two Cisco Expressway-E NICs, the TURN traffic and SIP traffic must reside on the same Cisco Expressway-E server. You must configure the static NAT address, DMZ external address, and DMZ internal address of the Cisco Expressway-E on the Cisco Jabber Guest server.
The web client uses TURN relays allocated on the Cisco Expressway-E to tunnel media into the enterprise. Media is sent and received in STUN encapsulated packets to the TURN server through UDP port 3478.
The Cisco Jabber Guest client allocates a call resource through HTTP to the Cisco Jabber Guest server.
The Cisco Jabber Guest server requests short-term TURN credentials from the Cisco Expressway-C through a secure HTTP request. Administrator credentials are used for authentication. The configured domain must be on the Cisco Expressway-C with Jabber Guest service enabled.
The Cisco Expressway-C creates the TURN credential and passes it to the Cisco Jabber Guest server.
The Cisco Expressway-C propagates the TURN credential to the Cisco Expressway-E through the SSH tunnel (port 2222).
The Cisco Jabber Guest server responds to the Cisco Jabber Guest client with the TURN credential and TURN server (Cisco Expressway-E) address (DNS or IP).
The Cisco Jabber Guestclient uses the TURN credential to allocate the TURN relay on the TURN server.
The following diagram is an example of the media flow for a Cisco Expressway-E with single NIC deployment of Cisco Jabber Guest.
Cisco Jabber Guest media does not go through the traversal link between Cisco Expressway-E and Cisco Expressway-C.
If the Cisco Expressway-E is behind a NAT, additional configuration is required on the Cisco Jabber Guest server to avoid the media flowing to the static NAT address. Turn on Static NAT mode and configure the static NAT address and DMZ external address of the Cisco Expressway-E on the Cisco Jabber Guest server. This allows media to be sent to the DMZ external address of the Cisco Expressway-E, avoiding NAT reflection on the outside firewall.
The following diagram is an example of the media flow for a Cisco Expressway-E with dual NIC deployment of Cisco Jabber Guest.
Media flows through the traversal zone between the Cisco Expressway-C and the internal NIC of the Cisco Expressway-E. It hairpins on the Cisco Expressway-E to the external NIC of the Cisco Expressway-E, and then is STUN/TURN wrapped before being sent to the client browser.
If the Cisco Expressway-E is behind a NAT, additional configuration is required on the Cisco Jabber Guest server to avoid the media flowing to the static NAT address. Turn on Static NAT mode and configure the static NAT address, DMZ external address, and DMZ internal address of the Cisco Expressway-E on the Cisco Jabber Guest server. This allows media to be sent to the DMZ external address of the Cisco Expressway-E, avoiding NAT reflection on the outside firewall.
HTTP and HTTPS traffic from Cisco Jabber Guest clients in the Internet is sent to ports 80 and 443 TCP respectively. Therefore the firewall between the Cisco Expressway-E and the public Internet must translate destination port 80 to 9980 and destination port 443 to 9443 for all TCP traffic that targets the Cisco Expressway-E address.
The Cisco Expressway-E redirects HTTP requests on port 9980 to HTTPS on 9443.
80/443 TCP are the standard HTTP/S administration interfaces on the Expressway. If the Cisco Expressway-E is administered from systems located in the Internet, then the firewall translation must also distinguish by source address and must not translate the destination port of traffic arriving from those management systems.
You also need to ensure that appropriate DNS records exist so that the Cisco Jabber Guest client can reach the Cisco Expressway-E. The FQDN of the Cisco Expressway-E in DNS must include the Cisco Jabber Guest domain. The Cisco Jabber Guest domain is the domain that is configured on the Cisco Expressway-C.
For more information on port usage for Firewall Traversal, refer to the Cisco Expressway IP Port Usage for Firewall Traversal Guide.

The Cisco Expressway-E administrator currently uses port 80 and therefore, incoming requests from the Cisco Jabber Guest client to Cisco Expressway-E on port 80 must be remapped to port 9980 using a firewall (or similar) in front of Cisco Expressway-E. For the mobile client, using 9980 in call links is not supported; you must use port remapping on your firewall to remap port 80 to port 9980.
The Cisco Expressway-E administrator currently uses port 443 and therefore, incoming requests from the Cisco Jabber Guest client to Cisco Expressway-E on port 443 must be remapped to port 9443 using a firewall (or similar) in front of Cisco Expressway-E. For the mobile client, using 9443 in call links is not supported; you must use port remapping on your firewall to remap port 443 to port 9443.

Inbound firewall rules are required to allow media to flow from the Cisco Expressway-E to Cisco Expressway-C.
You may find that two-way media can still be established even if the inbound from Cisco Expressway-E (DMZ) to Cisco Expressway-C (private) firewall rules are not applied. This is because the outbound media creates a pinhole in the firewall; however, these rules are required to support uni-directional media (that is, only from outside to inside).

Cisco Jabber Guest only supports a three-server cluster. Three operational servers are required for full redundancy.
Configure the reverse proxy to send requests to only one server in the cluster at a time. You set the order in which requests are sent on Cisco Expressway-C, from the Priority field in . Give each Cisco Jabber Guest server a different priority. Requests are sent to a different server only if a server becomes unresponsive.
Cisco Jabber Guest can be administered from any server in the cluster. To simplify troubleshooting, we recommend that you use one server in the cluster for administration purposes.
