[cisco-voip] Voice header compression Problem with IETFencapsulation

[Voll, Scott]

I had the same problem. The only work around I got from TAC was "don't
use rtp header compression"........

IETFencapsulation

 

Hello,

 

  I am trying to apply rtp header compression on a frame-relay
interface.

 

I am using the configuration below but error popping shows that header
compression is not supported with IETF encapsulation. I have to use IETF
as the other end of this connection is over ATM interface so Frame-Relay
to ATM internetworking is in the middle. What can be done to solve this
problem? 

 

Configuration Below:

==============

 

 

interface Serial0/0
 no ip address
 encapsulation frame-relay IETF
 no fair-queue
 frame-relay traffic-shaping
 frame-relay lmi-type ansi

 

error message while adding the ip rtp header compression or fr ip rtp
header compression:

 

Router(config)#interface Serial0/0
Router(config-if)#ip rtp header-compression    

 

%Interface is set for IETF encapsulation! IP header compression is
supported only over CISCO encapsulation! 


Router(config-if)#

Router(config-if)#frame-relay ip rtp header-compression 
%Interface is set for IETF encapsulation! IP header compression is
supported only over CISCO encapsulation!
