FreePBX and Gai-tronic communication

Hi all,

I have an situation that I’ve been beating my head on for the past day and hope someone can help me.

I have a FreePBX system that communicates to Gai-tronic PA/GA system through a Grandstream Analog gateway. Everything works as it should, I call the extension for it, it rings and then answers and I can leave a recording but only after I hit the number of which zone I need to broadcast out to. This is the correct behavior as well however my customer has become accustomed to not having to hit a number anymore because they only want to broadcast out to one particular zone now. I don’t own the PAGA side so I can not make any changes there. What I’m trying to accomplish is that the customer dials an extension, 1 in my situation, and it should immediately connect to the PAGA instead of ringing, and connect to the proper zone which is achieved by pressing 11. Any help would be very much appreciated. Thanks for taking the time to read my post.
