Sip Simple Why Was MGCP Developed When We Already Had H.323 & SIP?

Why was MGCP developed when we already had H.323 & SIP? - sip simple

Why MGCP was developed after H.323 and SIP?
I understand that debug messages H.323 is complex and difficult to debug, error, SIP has solved this problem with a simple text message / reply and best practices services SIP stack.
But the question is: What was the need for the development of the battery when MGCP, H.323 and SIP have prevailed in the market, how it is different VoIP network and a better quality for the end user and the network better that H 323 and SIP?
All the pros and cons of course ..
Not a question of distribution for pointers, and subjective responses that are good.

Thanks in advance

MGCP and H.248 are device control protocols, not session control protocols like H.323 and SIP. MGCP and H.248 are used by a device like a softswitch to control devices centrally, which is useful in some cases. In theory, MGCP and H.248 allow one to build simpler devices. It also allows a network operator to have tight control over the device, even capturing every dialed digit, like the old PSTN.

As for SIP being simpler than H.323, I disagree. If it were so simple, we would not suffer with so many interoperability issues around the world.
