Configuring Vj-Type Header Compression - Avaya G250 Administration

Configuring VoIP QoS
Use the ip rtp port-range command to configure the range of UDP ports for
●
RTP.
G350-001(config-if:Serial 5/1:1)# ip rtp compression-connections 48
Done!
G350-001(config-if:Serial 5/1:1)# ip tcp compression-connections 48
Done!
G350-001(config-if:Serial 5/1:1)# ip rtp max-period 512
Done!
G350-001(config-if:Serial 5/1:1)# ip rtp max-time 20
Done!
G350-001(config-if:Serial 5/1:1)# ip rtp non-tcp-mode ietf
Done!
G350-001(config-if:Serial 5/1:1)# ip rtp port-range 40000 50000
Done!
2. Use the ip rtp header-compression command if you wish to enable RTP, TCP, and
UDP header compression on the current interface. The compression method employed is
IPHC. Alternatively, you can use the equivalent command
ip tcp header-compression iphc-format.
G350-001# interface dialer 1
G350-001(config-if:Serial 5/1:1)# ip rtp header-compression
Done
Note:
Once header compression is enabled, any change to a header compression

parameter goes into effect immediately.
To disable IPHC-type header compression on an interface, use the no format of the command
you employed (in the interface context): no ip rtp header-compression or no ip tcp
header-compression.

Configuring VJ-type header compression

VJ-type header compression applies to TCP headers only.
Note:
You cannot specify VJ-type header compression for a Frame Relay IETF
Note:
interface.
1. Optionally, use the ip tcp compression-connections command to control the
number of TCP header compression connections supported on the interface. Use the no
form of this command to restore the default value of 16 connections.
G350-001(config-if:Dialer 1)# ip tcp compression-connections 24
Done!
