RE: RSVP FOR VOICE TRAFFIC!!Hi,

It is all about the matching of incoming dial-peer. Please see:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fvvfa
x_c/vvfpeers.htm#1264381.

By default, VOIP call using "csim start" will not match corresponding
dial-peer. If router cannot match the incoming dial-peer, it use a default
dial-peer to answer the call. The default dial-peer don't have the QoS or
CODEC settings and therefore the call will not work.

In real life, I think the call from phone may contains the calling number
information and therefore the command "incoming called-number" may not needed.
However, in a lab environment using "csim start" for testing, it is the only
way I found working if you want to set QoS/CODEC in the VOIP dial-peer.

HTH

William Chen

  Hi,

     The problem you have is that the two VOIP dial-peers don't associated
with each other.

     You need command "incoming called-number xxx" in the dial-peer
  configuration:

  > R1_Config
  >
  > dial-peer voice 3 voip
  >  destination-pattern 5000
  incoming called-number  5302
  >  session target ipv4:129.44.85.5
  >  req-qos guaranteed-delay
  >  acc-qos guaranteed-delay
  >
  >
  > R2_Config
  >
  > dial-peer voice 3 voip
  >  destination-pattern 5302
  incoming called-number  5000
  >  session target ipv4:129.44.85.1
  >  req-qos guaranteed-delay
  >  acc-qos guaranteed-delay

  Best Regards,
  William Chen
