Before we see how a CUCM translation pattern is configured, I suggest you to refresh your knowledge about the topic by checking the link here . A Translation Pattern can be set in routing mode or in blocking mode. We are going to configure an example of both in this article. For this, we are going to take as example the pattern 9999 and: expand it to a PSTN number once, then block it. Configuring a Routing Translation Pattern Under the translation pattern configuration menu, we create a new pattern, for example 9999. Then we set a Called Party Transform Mask of 9011442072431810, which emulates a PSTN number: Calling 9999 is successful will expand to a full number of 9011442072431810: Configuring a Blocking Translation Pattern We take the same pattern, and set it to blocking. We can add a custom cause code. And we try the call again. The line hangs up silently. What about an overlap with a route pattern? Trying to add a translation pattern that overlaps with a route pattern won’t ...

In this short post I am giving a solution to the HTTP Status 404 ccmadmin error in CUCM. This error occurs when the CUCM web server no longer responds. It may happen without prior notice and it can be a pain in the ass.   If you are running CUCM on Vmware and you’ve just installed CUCM, I highly recommend you take a snapshot, because it is possible that you will revert the image back to a previous point. Otherwise, here are the only options you’ve got: wait until the web server gets back online, which was recommended by a fellow engineer here . restart the web server from CLI. I’ll assume you are impatient so you choose option 2 :) By the way, to display the list of Cisco services in CLI, do a “utils service list” or better “utils service list page”, which allows you to browse the services page by page, by pressing the space bar. The web server service is called Cisco Tomcat . Sometimes you think Tomcat is started but it is playing tricks in t...

In this article I’m describing the implementation of site code dialing, in my CCNP Collaboration home lab. I am taking an example of one HQ with site code 801, and a branch office with site code 803.  The inter-site code I am going to use is the 0, to dial between sites. The purpose is to use inter site code dialing to reach other sites across the WAN, which is also called Toll Bypass . And if the WAN breaks then the communication takes place across the PSTN , which we also call PSTN fallback . CUCM configuration Gateway configuration Here is what the configuration would look like on the HQ gateway: and here is the part on the branch office site: In order to emulate PSTN, I set the following configuration: Testing the configuration First, when the WAN connection WAN is up between HQ and the branch site, we get the following result: and the WAN connection is disrupted, the communication falls back to PSTN:
