[SR-Users] detecting compact headers?

[Brooks Bridges]

We have an internal component of our callflow that does not support compact headers (vendor says it's on the roadmap but no eta, etc) so I'm trying to find a clean way to detect if a message has compact headers and reject it.  I haven't had much luck in finding a way to identify specifically if any of the headers of the message are compact however.  Can anyone point me in a direction please?

Thanks!
