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.

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.).
