My Greeting

Hello my dear reader,

Welcome to my blog, which is dedicated to voice technologies. On its pages we will talk about the limitless world of telephony and network technologies.

We will focus on solutions and technologies in the area of IP-telephony (mostly on Cisco, but I will try to speak about the others too.). These are IP PBX based on Cisco Unified Communications Manager and Cisco Unified Communications Manager Express, Cisco contact centers, Cisco Voice Gateways, etc. Also, I will introduce you the news from the world of education: Cisco courses, my own developed training programs, our upcoming events, online learning.

If you have any questions regarding my posts, job or activities, please feel free to ask your questions. I will try to answer them when I have time.

Dropping Conference in CUCME When Initiator Disconnects

Hello all!

This post is a response to a question from a student of my recent CVOICE course. The question was as follows - how to drop a hardware Conference  in CUCME when initiator of the Conference is leaving the session.

The solution is easy. In ephone or ephone-template configuration just add a command conference drop-mode. Its syntax is:

conference drop-mode [creator | local]

Parameter creator means Conference is stopped when initiator leaves it. Parameter local says Conference is stopped when the last internal CUCME's phone disconnects from the session (ie prevents a situation where the conference are used by external subscribers only).

An example of configuration is here:

HQ-1(config)# ephone 1
HQ-1(config-ephone)# conference drop-mode creator


Wish all of you a nice day!

Presence for Сall Manager Express

Hi folks,

Today we are talking about how to set up Presence feature on the CUCME (Call Manager Express). Presence allows a user (watcher) to monitor the real-time status of another user at a directory number or SIP URI from the device of the watcher. Before making a call, one can visually see whether the other party is busy or whether it is free. Viewing the status of the DN can be configured for speed-dial buttons (Speed ​​Dials) or for call lists (Placed Calls, Missed Calls, Personal and Corporate Directories). Moreover, you can also view subsriber's status of the remote PBX. It is possible if you have a trunk with SIP signaling between those PBXs.
