[Fedorov, Konstantin]

Yes,

On the WAN, you can.
One note, cRTP must be configures on both side of link.

Yep.... I have already done both of those.  Using G.723 (5.3kb/s) and
60ms
sampling.  Even with a 40 byte payload, the packets are mostly headers.
The
WAN links are BRI interfaces, so I might try using IP header compression
on
the outbound WAN interfaces.

Cheers,
Eric

Hi,

>From my opinions you couldn't use cRTP on broadcast network. It's only
appropriate on p2p links. If you want save bandwidth on LAN, look to the
1/
Different codec 
2/ Lager payloads

Does anyone know if/how you can use Compressed RTP from an IOS Gateway
(H.323 mode) to terminate trunk calls on CallManager 4.1.3?  I have a
few
IOS Gateways that are currently trunk connecting into pre-arranged adhoc
conferences.  I was hoping I could utilize cRTP to further save
bandwidth.

Cheers,
Eric
