Jabber Client Connectivity Without VPN
The mobile and remote access solution supports a hybrid on-premises and cloud-based service model, providing a
consistent experience inside and outside the enterprise. It provides a secure connection for Jabber application traffic
without having to connect to the corporate network over a VPN. It is a device and operating system agnostic solution
for Cisco Jabber clients on Windows, Mac, iOS and Android platforms.
consistent experience inside and outside the enterprise. It provides a secure connection for Jabber application traffic
without having to connect to the corporate network over a VPN. It is a device and operating system agnostic solution
for Cisco Jabber clients on Windows, Mac, iOS and Android platforms.

C and Expressway-E, and how to discover the Unified CM servers and IM&P servers used by the service.
Installing Expressway Security Certificates and Setting Up a Secure Traversal Zone
To support Unified Communications features (such as mobile and remote access or Jabber Guest), there must be a
Unified Communications traversal zone connection between the Expressway-C and the Expressway-E. This involves:
Unified Communications traversal zone connection between the Expressway-C and the Expressway-E. This involves:
■
Installing suitable security certificates on the Expressway-C and the Expressway-E.
■
Configuring a Unified Communications traversal zone between the Expressway-C and the Expressway-E
For information about how to do this, see:
■
not already have a secure traversal zone in place)

Note that if XMPP federation is to be used, the IM&P servers need to be discovered on the Expressway-C for all the
relevant information to be available when generating certificate signing requests.

Setting Up the Expressway-C
This section describes the configuration steps required on the Expressway-C.
Configuring DNS and NTP Settings
Check and configure the basic system settings on Expressway:
1.
Ensure that System host name and Domain name are specified (System > DNS).
2.
Ensure that local DNS servers are specified (System > DNS).
3.
Ensure that all Expressway systems are synchronized to a reliable NTP service (System > Time). Use an
Authentication method in accordance with your local policy.
