Optionally, configure the following header compression parameters.
ADDITIONAL INFORMATION:
If you do not configure these parameters, their default values are used.
ip rtp compression-connections
ip tcp compression-connections
ip rtp max-period
ip rtp max-time
ip rtp non-tcp-mode
IETF mode is not compatible with non-IETF mode.
ip rtp port-range
For example:
Gxxx-001(config-if:Serial 4/1:1)# ip rtp compression-connections 48 Done! Gxxx-001(config-if:Serial 4/1:1)# ip tcp compression-connections 48 Done! Gxxx-001(config-if:Serial 4/1:1)# ip rtp max-period 512 Done! Gxxx-001(config-if:Serial 4/1:1)# ip rtp max-time 20 Done! Gxxx-001(config-if:Serial 4/1:1)# ip rtp non-tcp-mode ietf Done! Gxxx-001(config-if:Serial 4/1:1)# ip rtp port-range 40000 50000 Done!
Use the ip rtp header-compression command if you want to enable RTP, TCP, and UDP header compression on the current interface.
ADDITIONAL INFORMATION:
The compression method employed is IPHC. Alternatively, you can use the following equivalent command: ip tcp header-compression iphc-format
For example:
Gxxx-001# interface dialer 1 Gxxx-001(config-if:Dialer 1)# ip rtp header-compression Done
ADDITIONAL INFORMATION:
Note:
After header compression is enabled, any change to a header compression parameter is effective immediately.
To disable IPHC on an interface, use the no form of the command you employed (in the interface context): no ip rtp header-compression or no ip tcp header-compression.
