The Edge appliance proxies the request through the Core to the REST API on Unity Connection.

CHECK TFTP CLIENT CONNECTION REGISTRATION

If the Jabber client is provisioned with visual voicemail, the Jabber client will submit registration requests to the Edge appliance using the already established TLS connection on port 8443. Successful registration is required for voice/video call functionality. Registration requests are sent to the Edge appliance, which is then proxied through the Core appliance to the UCM cluster node(s). If the Jabber client is provisioned as a voice/video soft phone, the client will attempt to establish a connection on TCP port 5061. Registration requests are sent to the Edge appliance, which then proxies the transaction through the Core appliance to the IM&P cluster node(s). If the Jabber client is provisioned for IM&P presence services, the client will attempt to establish a connection on TCP port 5222. This configuration information is used to complete the service registration phases. At this point, the proxy connection is established and the client will start downloading configuration information from the UCM cluster. Once the client establishes a TLS connection to port 8443 on the Edge appliance, the user credentials are authenticated. In a properly implemented solution, this query should return one or more records that point to your Expressway Edge (or VCS-E) cluster.Īssuming everything is configured correctly and fully operational, the Jabber client will attempt to establish a TLS connection to one of your Edge appliances. If the client fails to receive a positive response to the UDS/cuplogin queries, it will then send a DNS SRV query for _collab-edge._. In an MRA scenario, where a client is outside of the corporate network, the above SRV records should not be resolvable. _cuplogin._: Legacy record that points to XMPP service on IM&P service _cisco-uds._: Points to the UDS service on a UCM cluster Once the service domain is known, the Jabber client will go through the sub-process of Service Discovery. The service domain is usually specified by the user the first time they attempt to log into Jabber, though the service domain can also be administratively assigned in the jabber-config.xml file. For example, if my JID is then the service domain is . The service domain is derived from the Jabber ID (JID) assigned to the end user. Specifically, the Jabber client will query for specific DNS service records (SRV record) based on the assigned service domain.

At this stage, the client is trying to determine if it is inside the corporate network or outside. Upon initialization, the Jabber client enters into a “Service Discovery” mode.

Procedures were originally developed with the 10.x version of Jabber running on Mac OS X and Windows. We are also roughly following the sequence of transactions that are actually used by a Jabber client. This blog entry is focused on a scenario where we are using corporate presence services and UCM for call control. Establish Visual Voicemail connectivity.

If you need a review of the architecture with a walk-through of the Jabber client discovery and registration process, then a PDF of that presentation is available here.Īt a high-level, the MRA registration process follows this flow: I presented on the MRA registration process during a NetCraftsmen Cisco Mid-Atlantic User Group (CMUG) meeting last year. Proper troubleshooting technique requires that you have a thorough understanding of how things should work during normal operations. These procedures can be used to validate the initial deployment or they can be used to troubleshoot connectivity problems for an individual user. This blog entry captures procedures I use when troubleshooting or validating an MRA deployment. And, like most things, the first time you deploy MRA there are a few “gotchas” that can eat up a significant amount of troubleshooting time. Like most things, there are a lot of moving parts working together to create a relatively seamless user experience.

The Cisco Mobile and Remote Access (MRA) feature is a “client edge” solution that allows external software and hardware clients to register to enterprise Cisco Unified Communication (UC) solutions without requiring a VPN. He was kind enough to let us repost it here, and we think many technologists will find it valuable. The following blog post originally appeared on, a site where our own William Bell writes about unified communication technologies. Editor’s Note: Sharing expertise with other industry professionals is part of being a true Master Craftsmen, and so it’s an important aspect of the NetCraftsmen mission.
