Shorting the lines should create an off-hook situation (busy).  If you have roll over or a trunk group then you need to do it to all the lines.  Also if you have voicemail at the carrier level, that must be turned off.

In asterisk you can use app congestion.

It sounds like the Meridian GSM devices connect via analog line so if you connected the ports on the Meridian currently terminating into the GSM devices go into asterisk via a four port FXS (guessing the GSM devices supply dialtone) then the routing in the Meridian would not change and your calls would go to the asterisk machine.
