A company-wide rollout of any new application including Cisco Jabber can be fraught with challenges that may or may not be readily apparent to the organization. Even small issues can potentially jeopardize the success of an entire project. For this article, we will look at how proper planning and modeling can help eliminate these issues before they become big.
If you are a sports fan like me, particularly American football, the number 12 is synonymous with excellence. From Joe Namath, Terry Bradshaw and Jim Kelly to Tom Brady, the number 12 is identified with some of the best players ever to hit the field.
Recently, Cisco released Jabber 12. In this article, we will look at all that is exciting and new in Jabber version 12.0, and see if it lives up to the magic of the number 12.
Update:It has been recently announced that the changes that Apple would make to the iOS notification architecture after iOS 11 will not currently affect Jabber notifications for IM and calls for customers that have not yet upgraded their infrastructure to support Apple Push Notifications (APNs). However, it is still recommended to upgrade.
Push Notifications are required both for Cisco Jabber for iPhone and iPad clients that connect from within the enterprise network as well as for clients that register to an on-premise deployment via Expressway's Mobile and Remote Access (MRA) feature.
In this third article, we will expand upon what we learned in part 1 and part 2 regarding Jabber and how to renew your CA-signed certificates. In this final article, we will examen the certification process within Cisco Expressway.
It is important to note that for Jabber Mobile and Remote Access (MRA) feature as well as for Business to Business calls (B2B), it is mandatory to have a CA-signed certificate on the Expressway-Edge node. On the other hand, there is no such requirement for Expressway-Core. However, Stack8 recommends a CA-signed certificate to be used on both Expressway servers.
Another requirement is to cross upload all Root and Intermediate certificates on both nodes in order for the Secure Traversal Zone to be active and communication between two Expressway nodes to work.
Do not forget to verify, every time you renew your certificates, if there is a change on the Root or any of the Intermediate certificates and Upload all new chain certs in the Trusted Certificates section of the server.
