I got call from P. Kanet asking about alarm system similar to previous NEC's project. Then P. Boolert calls with similar requirement so I think this is the same project.
They want to connect to alarm system and call to predefined number: mobile, fix line, etc. But alarm provide API or IP protocol. Connection to PBX will be sip trunk. P. Boonlert seems confident to get this project. He asked us to prepare. So he will send document for alarm interface for us to quote.
I will forward document as soon as I get it. In the mean time, check out installed alarm system if there is any complain.
