[cisco-voip] Voice header compression Problem with IETFencapsulation

[Yasser Aly]

Scott,
 
  So how you solved your problem??
How did you manage to compress voice packet headers while still using IETF?

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

..

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!
