Why my mitel sx-50 shows message on console no communication?

The phone line between the SX-50 console and the main control is disconnected or the console may need to be rebooted (unplug the phone line then reconnect it). If this doesn't solve it then contact your PBX system support person.

Mitel SX-20: How to allow toll free dialing of 1-866 and 1-877 numbers. Currently system only allows 1-800 dialing. Any suggestions will be greatly appreciated.

I don't believe the SX20 can be set up for these additional numbers. The SX20 has been unsupported for over 20 years. Most vendors have stopped help on them. You really should get a new system.

We have an old mitel PABX console system with this info on the back: 9102-018-000-NA (serial #ACAAZ45-15). Don't have a manual and need one. Any ideas?

Well, you could just put that number in a search engine and get some pretty good hits. You would find that it belongs to an SX-20 Generic 500/503.

Now the tricky part. Perhaps a Mitel manual site?

Negative, the SX 50 does not support CID. You can upgrade the Mitel or use a CID Multi line interface to a PC. Here is one such model.
