MGCP

Here is MGCP in plain terms. HostedSwitch® provides VoIP softswitching in the format of Software-as-a-Service (SaaS). In practice that means managing your IT, from help desk to infrastructure, as an outside partner.

The natural audience is small and mid-sized companies. Alongside the main category they mention Cloud Computing, Public Relations, Telecommunications and VoIP. As a small company team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

MGCP is based in Santa Clara, California and around since 2000. Their site is hostedswitch.com.

Before you commit, look at response SLAs, onboarding, and what is billed per hour. Ask for a trial on your own data, not a canned demo.
