Serial Link VoIP/RTP QoS

Unanswered Question
Apr 12th, 2007

Hi there,


I'm wanting to setup some sort of VoIP/RTP QoS on a 2MB link between a satellite site and HQ. I have approx 20 handsets at the remote site. I have setup the following QoS rules on both remote and HQ routers, 2620's with IOS 12.2.


Router-HQ#sh run

call rsvp-sync

controller E1 1/0

!

class-map match-all class1

match access-group 101

!

policy-map policy1

class class1

bandwidth 2048

random-detect

random-detect precedence 0 32 256 100

!

interface Serial0/0

bandwidth 2048

encapsulation ppp

ip tcp header-compression iphc-format

ip rtp header-compression iphc-format

ip rtp compression-connections 64

ip rtp reserve 16384 100 800

!

Router-HQ#


I am trying to implement a more aggressive queue QoS method than just ip rtp header-compression?


Does anyone have any recommendations regarding my bodged attempt??


Much appreciated, Cheers!
