Hi!

I am trying to configure two Cisco routers MC3810 and 1750-4V to do Voice
over Frame Relay. Both the router have the latest IOS. As soon as I enable
the vofr cisco command, all my data communications stop. I cannot even ping
across. BUT the funny bit is that voice can go through!!!

The config on the MC 3810 is :

!
interface Serial0
 bandwidth 64
 no ip address
 encapsulation frame-relay
 frame-relay traffic-shaping
 frame-relay lmi-type ansi
!
interface Serial0.1 point-to-point
 bandwidth 48
 ip address 10.1.1.5 255.255.255.252
 frame-relay interface-dlci 16
  class Voice
  vofr cisco

map-class frame-relay Voice
 frame-relay voice bandwidth 32000
 frame-relay fragment 80
 no frame-relay adaptive-shaping
 frame-relay cir 48000
 frame-relay bc 1000
 frame-relay be 16000
 frame-relay mincir 20000
 frame-relay fair-queue

The config on the 1750 is:

!
interface Serial0
 bandwidth 64
 no ip address
 encapsulation frame-relay
 no ip mroute-cache
 frame-relay traffic-shaping
 frame-relay lmi-type ansi
!
interface Serial0.1 point-to-point
 bandwidth 48
 ip address 10.1.1.6 255.255.255.252
 no ip mroute-cache
 frame-relay interface-dlci 16
  class Voice
  vofr cisco

map-class frame-relay Voice
 frame-relay cir 48000
 frame-relay bc 1000
 frame-relay be 16000
 frame-relay mincir 20000
 no frame-relay adaptive-shaping
 frame-relay fair-queue
 frame-relay voice bandwidth 32000
 frame-relay fragment 80

Can someone please explain what am I doing wrong and how can I make this
work??

Any Help will be appreciated.
