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 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



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!
