We're looking at adding an intercom solution to facilitate conversation between our operators on one side and on the other side truck drivers that are waiting on a truck scale while product is being loaded. I can work with a direct point to point intercom or we do have a FreePBX phone system and the operations room already has a phone in that location that could be used for that side of the link.
The concern I have though is that the speaker/microphone on the truck scale side will be in a fairly noisy environment since even idling those trucks generate a fair amount of noise. The proposed mounting position for the equipment on the truck scale will be a good 3-4 feet from the driver as they are sitting in the cab of their trucks and I'm concerned that may be too far away for them to hear or for the microphone to pick up what they are saying.
Has anyone worked with a vendor that makes an intercom speaker/microphone solution that would work well in a noisy environment such as this? I would prefer a SIP solution but would consider other if that's what is needed.
