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.

Profile Photos for CUPC / Jabber

Good afternoon,

In my newpost, I want to talk about how to add user avatars (profile photos) for CUPC or Jabber centrally. Using these communicators becomes much more interesting and more convenient if we visually see a photo of our contact. But not everyone knows how to make avatars to be displayed on your device. This is what we will talk about in the next few minutes.

CUCM Call Routing Based on Calling Number

Good day,

Today's post will focus on the subject, which have been increasingly interested in by my students and blog readers. We will talk about how to route the call in CUCM depending on the number of the caller. This problem arises, typically, in situations where you want to block incoming calls from certain numbers, or, vise versa, to allow incoming calls only from certain numbers and all other call must be denied. Consider, for example, that the second task, ie, let's deny all incoming calls, except calls from certain numbers.

CUCM SIP-trunk to ITSP (via CUBE)

Good day,

Many of my readers and students are very interested in the task of how to connect CUCM to IP telephony service provider via SIP-trunk. This topic is very relevant, as more and more providers offer SIP services and connections, in addition to traditional E1 or BRI lines. This post will discuss the basic settings for SIP-trunks (ie without DTMF, fax settings, transfers, etc.).
