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.
Just a thought,

Subject: [VoiceOps] TMobile Sending Calls to LRN not Called Number
Anyone else seeing calls from TMobile coming in with the LRN as the
called number? The ISUP doesn't show the actual called number so we
can't route the calls.
