VCS architecture, components, call control and integration with CUCM

Posted on by Admin

VCS 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…

CUCM Database replication, how it works

Posted on by Admin

CUCM 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…

Posted on by Admin

External Voice mail access, using Unity Connection

Posted on by Admin

  External 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…

Cisco Unity Connection greeting administrator

Posted on by Admin

Cisco 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…

Direct Transfer to Voicemail

Posted on by Admin

Direct Transfer to Voicemail   This post describes how to configure direct tranfer of calls to a person’s voicemail. So without ringing that person’s extension and without going through the opening greetings. Believe me, receptionists love this! First of all,  create a separate voicemail profile for this purpose, using the existing VM pilot (5999 in this case):     Secondly, add a CTI Route Point:         This CTI Route point will never…
