Interface with Valcom Class Connect?

I’m trying to use a Grandstream fxo and viking pa-1a to connect to a valcom class connect system. In essence they are telling me I need to basically “flash” the line to open connection to the valcom device and then dial the zone i want to page over. The problem is if I dial 900 utilize the trunk I have built to the grandstream device it then sends the 900 to the valcom which it doesn’t want.

Any ideas how I can grab the line and then dial the necessary digits for the valcom?
