Viewing Core dumps CUCM Core dumps, ah yes! The boring stuff. Some times an unavoidable part of a troubleshooting process. they can be particularly useful if you see certain services restart on your server for no apparent reason. This is a quick little post on how to obtain core dumps and how to capture their output and what to look for once you have the output. What are they? Core dumps occur when a Linux process…
Read MoreCall recording configuration in CUCM Call recording. This boils down to capturing RTP streams and somehow matching a certain RTP stream to an extension and or user ID, so it can be archived properly on a recording server. In order to do this, two things will need to be in place: Some form of RTP stream replication/forking, so that a conversation can take place as well as a recording of this same conversation at the…
Read MoreAutomatic Call recording using DMS and Verint In this post I want to show how to set up call recording in CUCM, using DMS in conjunction with, for instance, Verint. But before I do this I want to dig into the theory behind this setup. DMS stands for Dual Media Streaming. Call recording solutions that use DMS, make use of a phone’s ability to fork an incoming call, to a second destination, such as…
Read MoreVCS architecture, components, call control and integration with CUCM VCS, Video Communications server or is it just a fancy Gatekeeper? Well at least its not called “vucs” (video unified communications server). Has Cisco finally realised that they are misusing the word unified? The Telepresence architecture design guide states: “As the Unified Communications and TelePresence markets continue to grow and mature, the line between the two markets continues to blur. Both TelePresence and Unified Communications video devices…
Read MoreCUCM Database replication, how it works CUCM Database replication, how it works, or how it doesn’t. And when it doesn’t, the shit has hit the fan. I am really hoping that this particular post will expand an improve, because there is very little information available about the internals of the various UC platforms. That is probably Cisco’s way of trying to hide the fact that there is not much Cisco technology behind those platforms, but…
Read MoreCisco Real time Monitoring Tool (RTMT) Alerts and email notification Writing this post because I was working on customizing alerts that can be generated by Cisco’s Real Time Monitoring Tool. RTMT is by far the easiest tool for for performance monitoring and alert generation, on either CUCM, CUC as well as CUPS. So Lets get cracking. The start off point for most people, when using RTMT, is the alert central (See below) Fig. 1…
Read MoreDirected Call Park, as an alternative for transfers on an analog phones Well this is going to be an easy a short post. I am quite convinced, there are quite a few people around that have analog phones deployed in a, for the rest, all out IP phone deployment. I have seen this a number of times, analog phones on FXS ports (MGCP, SCCP or H323) and I have also seen issues with transfers…
Read MoreExternal Voice mail access, using Unity Connection External voice mail access. Yes, often requested, hardly ever used in my experience. The solution described below is also good for VM that gets dumped on shared mail boxes, where people don’t have the extension configured on the phone (for instance IVR overflow, or no agents logged in). This access will allow a user not only to listen to messages, but also to change greetings and other…
Read MoreCisco Unity Connection Call Handlers Call Handlers are a very good way to implement simple call flows. For more complex call flows and IVR’s; CUC is definitely not the place. CUC is the place to set up call flows for extension that require an automated open/closed greeting for instance for reception numbers. This is exactly what I will elaborate on in this post. There are a few steps that will need to be taken in…
Read MoreCisco Unity Connection greeting administrator This post will have some similarities with the one i did a while ago on call handlers and open/closed greetings. Mais alors, greeting administrator, what is it? It is basically a Telephony user interface (TUI) to administer greetings for call handlers. I had created a call handler with x100 that would play greetings based on TOD and holiday schedules and if open would transfer a caller to x105 which…
