Please do not click links unless you recognize the source of this email and know the content is safe. I'm not an expert in how STIR/SHAKEN is implemented in the TDM world, but I've never heard of this happening until recently. I've heard anything sent over the SS7 network has issues with the token being dropped. Maybe the problem is bigger than just the token being dropped.....maybe what they are doing is causing the called number to be dropped as well! That's the only reason I can come up with as to why one would get the LRN but not the called number.
