Parameters
nonstandard
: Specifies the nonstandard encapsulation format. If you do not specify this keyword,
packets are encapsulated in standard format. You must specify this keyword when the device
communicates with a non-H3C device. If you specify this keyword, this command enables RTP
header compression.
Usage guidelines
IPHC includes RTP header compression and TCP header compression.
Enabling or disabling IPHC enables or disables both RTP header compression and TCP header
compression.
To use IPHC, you must enable it on both sides of a PPP link.
When you enable IPHC on a VT, dialer, or ISDN interface, the setting does not immediately take
effect. For the setting to take effect, execute the
shutdown
and then
undo shutdown
commands on
the interface or its bound physical interface.

[Sysname-Serial2/1/0] ppp compression iphc enable
ppp compression iphc rtp-connections
Use
ppp compression iphc rtp-connections

an interface can perform RTP header compression.
