Update: I did go with a voip box + passive noise cancelling closed ear headset.
Hello I have several small sites built out that are only 10-15U in a single cabinet in different places around the world. They all have Mikrotik as the primary management switch. One thing I really have a hard time dealing with is working with remote hands at all these various sites. Has anyone found a good IP noise cancelling headset to plug into the Mikrotik (assume all sites have internet access and DHCP). I would like to leave a corded (long cord) headset sitting in each of these cabinets on a hook for the remote hands folks to use while they are working for both their sanity and mine. Note that in some cases the remote hands folks are in dead cell phone zones, which makes certain projects that require a lot of input and assistance from me to go from 2 hours to 14 hours or more (a mini-nightmare). Was debating something perhaps from 3M/Peltor ( https://pack-n-tape.com/Peltor-TM-Communications/ ) combined with some kind of IP phone driver module, but I'm sure someone here has come across a more elegant all-in-one just works when you plug it in RJ45. It need not actually use a phone number (could be some kind of point to point audio call over the internet) but am open to phone number based solutions as well. Be creative as you like, the only constraints are having a human being on the other side being able to hear me and me being able to hear them, without having to worry about battery replacements.
Thanks for the input!
