 ip rtp header-compression

Investigate this command and see what it does for your application. It
should take the IP/RTP/UDP header down from 40 bytes to 2-4 bytes.

Subject: OT: Voice compression

Hi,

I have a dedicated VoIP circuit, HDLC. What can I do to get the better
compression? I'm using g729, but it looks like each call takes about 30kb.(I
look at the load in the serial line). I would expect it to be lower. Is the
load number in 'show interface serial' accurate ? What is your experience ?
Thank you, /lillemor .
