Well, the two D-Link VoIP units have arrived, however they turned out to be 1120M units, not 1102M. The firmware I planned to use is also for the 1120, see

If you have the login_id and password for your 1102 mgcp units you may be able to use them with an Asterisk PBX. Asterisk supports MGCP phones and will allow you to use them with a SIP based VoIP provider. Sometimes you can get passwords from monitoring a console port during the boot process.
