Usage guidelines
When IPHC RTP is enabled on an MP link, the compression is performed on the VA interfaces. In this case,
you can check the compression information on MP templates, such as VT or Dialer.
When IPHC RTP header compression is enabled on a normal PPP link, the compression is performed on
the physical link. In this case, you can check the compression information on the physical interfaces only.
