CUCM SIP-trunk to ITSP (via CUBE) basic configuration

Good day,

Many of my readers and students are very interested in the topic of how to connect their 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 (i.e. without DTMF, fax settings, transfers, etc.).
