From X The main benefit of this feature is to generate low-cost server certificates to identify the Expressway-E, thereby reducing the cost of Expressway-based deployments like MRA Mobile and Remote Access.
Due to the underlying validation mechanism this feature is most likely to be useful for MRA deployments. The configuration process is simple. You enter some information on the Cisco Expressway-E to create a certificate signing request CSRthen the Expressway's ACME client interacts with the certificate authority to request the certificate.
Expressway downloads the certificate and you click a button to deploy it. After this manual step, you can schedule renewal so that the certificate does not expire—because ACME certificates are deliberately short-lived. You can manage this risk with the Expressway's security features or, for highly secure environments, you can disable ACME and use the traditional CSR procedure with your preferred certificate authority.
ACME is a client server protocol that enables automated certificate management of web hosts. We currently work with the Let's Encrypt authority to generate server certificates.
We also use ACME to generate domain certificates for SNI multitenancyfor which the process is essentially the same as the server certificate process. The ACME Certificate Service on the Expressway-E is a different method of requesting and applying server certificates to Expressway-E than the method described in the other parts of this document.
The ACME certificate service follows this process, but it removes the cost and some of the manual effort. One caveat about the process is that the CA has to interrogate the submitting host to verify that it controls the domains in the CSR. Let's Encrypt only issues the certificate after it successfully reads all the challenge files.
Each Expressway-E peer starts a virtual Apache host, configured to serve only the challenge files. If the challenge exchange was successful, then the client downloads the signed certificate, stores it in a staging area, and notifies you that the certificate is ready to deploy.
Expressway-E signals to other internal processes that they need to reload the server certificate. You do not need to restart the Expressway-E.
Providing an automated renewal mode, that fetches a new certificate when two-thirds of the validity period has expired. There is no notification at the two-thirds time if the service is not in automated mode. You are responsible for submitting a new signing request. The Expressway processes that use the certificate can load the new certificate without restarting. Expressway-E does not drop TLS connections, and presents the new certificate for new connection attempts.All our cisco jabber calls are through expressway.

Accepted Solutions. Re: cisco jabber: call recording through expressway. Thank you for your reply.Unwanted automatic call hitting on my Expressway E.
Go to Solution. In short, you can block these types of calls by a combination of CPL and search rules, the relevant section in the admin guide is referenced in some of the threads. You won't be able to stop these calls hitting your E, but at least you can prevent these calls from succeeding, yes, they will show up in the call log, but that's it.
If you want to block all incoming external calls, then you would need to put it behind a firewall and not allow anything from external.
View solution in original post. SIP UDP is disabled by default by Cisco, and should only be turned on if you need to support voice services on the Expressway, it is not required for video.
An upside to having SIP UDP turned off is that outbound calls will connect quicker - only "downside" I have found is that I'm not able to call hostnames, ie. Turning off SIP udp will stop those particular calls, however, you won't be able to stop the H. They will still show up in your call history though, just like the ones in your screenshot.
None of those calls shown in your screenshot have succeeded by the way. Even though you specified an "Unauthenticated User", the built in web interface for the CPL rules are based on authenticated requests.
If you look at the generated CPL script, it uses "origin" as the source, it should read "unauthenticated-origin". You'll need to look in the search history of the calls to see if they appear as authenticated or unauthenticated.
Cisco Expressway Certificate Creation And Use Deployment Guide (X12.5)
If unauthenticated, you'll need to create a custom CPL script yourself to block these calls. This will prevent most of these unwanted calls, however as mentioned this will not stop all attempts. You can use CPL to prevent the remaining calls from consuming call licenses, there are some example CPL scripts in the forums depending on the how the incoming call is formatted.
Nikhil didn't block everything, the rules are based on source and destination, so the calls must match both fields in order to take affect. So because he used. Buy or Renew. Find A Community.

This is a very well known. Please rate replies and mark question s as "answered" if applicable.A vulnerability in the management web interface of Cisco Expressway Series could allow an authenticated, remote attacker to perform a directory traversal attack against an affected device.
The vulnerability is due to insufficient input validation on the web interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web interface. A successful exploit could allow the attacker to bypass security restrictions and access the web interface of a Cisco Unified Communications Manager associated with the affected device.
Valid credentials would still be required to access the Cisco Unified Communications Manager interface.

Include everyone in your meeting regardless of the system they use. Find out how.The following major Expressway-based deployments do not work together. They cannot be implemented together on the same Expressway or traversal pair :. Expressway-C uses round robin to select a node publisher or subscriber when routing home cluster discovery requests. That is, we do not support traversal zones, or Unified Communications traversal zones, between Cisco VCS and Cisco Expressway even though it is possible to configure these zones.
MRA is not currently supported over chained traversal connections using multiple Expressway-Es to cross multiple firewalls.
This means that you cannot use Expressway-E to give Mobile and Remote Access to endpoints that must traverse a nested perimeter network to call internal endpoints.
You should use the Expressway-E for this purpose. You could potentially place the Expressway-C in a DMZ that does not use static NAT, but we strongly discourage this deployment because it requires a lot of management on the inmost firewall.
We always recommend placing the Expressway-C in the internal network. Skip to content Skip to footer. Book Contents Book Contents. Find Matches in This Book. PDF - Complete Book 5.

Figure For a new hybrid connector host, you must register an Expressway box with the latest software release to the Webex cloud.
For existing connector hosts, we support the two latest major released versions of Expressway. Make sure that you update the Expressway software on your connector hosts as often as possible. You must also upgrade to the latest stable connector release as a prerequisite for technical support. You must keep your Expressway-C connector host for hybrid services up to date.
You can download the latest Expressway software, free of charge, from software. See the following tables for more information about the currently supported versions and what to expect when you need to upgrade your Expressways. See Upgrade the Connector Host Expressway used for your Hybrid Services for the correct sequence to upgrade your Expressways that are used for connector hosting. See the deployment guides for CalendarCallMessageand Serviceability for how to register your Expressway securely to the cloud, so that the Expressway can host hybrid connector software.
Expressway is the platform on which connector software is downloaded, run, installed, and upgraded automatically from the cloud. For connector upgrade management, see the related articles for upgrade schedules and release notes. For new Expressway connector hosts, you must register to the cloud using X You'll see an error message in Cisco Webex Control Hub if you try to register a version that's not supported for hybrid services.
For existing Expressway connector hosts that are already registered to the cloud, we support the two latest released versions —the most recent major release for example, X For Expressways that are at risk of being unsupported for hybrid services, you'll receive advanced notice on the Expressway that reminds you to upgrade to the latest version.
The Expressway version your hybrid deployment is running on determines the reminder that you see; both cases are covered in the following table. For Expressways that are one release behind the latest, you'll receive advanced notice on the Expressway that reminds you to upgrade the latest version. Connector software still automatically downloads, installs, and runs, and your deployment is still supported, but we recommend that you upgrade to the latest version at your earliest convenience.
For Expressways that are two releases behind the latest, you'll receive a warning that the version is no longer supported for hybrid services. Connector software still automatically downloads, installs, and runs, but your deployment is considered unsupported and at risk of not working until you upgrade to the latest version as soon as possible.
