Hi Mike,

Can you try removing this?

Sep 18 12:11:13.637 PDT: RADIUS:  Framed-Compression  [13]  6   VJ
TCP/IP Header Compressi[1]

It has no impact and for ASR1Ks it's not supported (so I assume it
isn't supported on ASR920s either). I've had an issue in the past with
ASR1Ks where that was stopping subscriber sessions from establishing,
in combination with another AVP but without that 2nd AVP the session
would establish even though compression isn't supported. It was only
in that combination that the issue was highlighted. If you're using
something like FreeRADIUS it's in there by default, so you need to
look to remove it from the default config.

Cheers,
Janes.
