IP RTP header compression statistics:
Interface Serial 3/1:1.1:
  Rcvd:    0 Full Headers, 0 Compressed, 0 Errors
  Sent:    9 Full Headers, 394 Compressed,
           8274 Bytes Saved, 14202 Bytes Sent,

           Max Time 5, Max Period 256

Output fields

Name
Description
Rcvd
Information on received RTP packets, as follows:
  • Full Headers — the number of RTP packets with full headers received
  • Compressed — the number of RTP packets with compressed headers received
  • Errors — the number of packets discarded during de-compression due to errors
Sent
Information on sent RTP packets, as follows:
  • Full Headers — the number of RTP packets with full headers sent
  • Compressed — the number of RTP packets with compressed headers sent
  • Bytes Saved — the total saving in bytes due to compression
  • Bytes Sent — the total number of bytes sent after compression
  • Efficiency Improvement Factor — the improvement factor, calculated as (bytes saved + bytes sent)/ bytes sent (rounded to two decimal places)
Connect
Connection information, as follows:
  • Active/Inactive — whether RTP header compression is negotiated and working on this interface
  • Rx Slots — the number of RTP sessions to decompress
  • Tx Slots — the number of RTP sessions to compress
  • Max Time — the maximum number of seconds between two full header packets
  • Max Period — the maximum number of compressed packets sent between two full header packets
