• The maximum number of RTP/TCP header-compression connections configured on an interface is
inherited by all VCs of the interface. If you set a different maximum number on a VC of the interface,
the configuration on the VC takes effect.
• Frame Relay IPHC and STAC compression are mutually exclusive.

By default, Frame Relay IPHC is
disabled.
If you specify the nonstandard
keyword, only RTP header
compression is supported, and
TCP header compression is not
supported.
4. Set the maximum number of
RTP header-compression
connections allowed.
