86 IBM Voice Over Frame Relay Perform Guide
4. Set the frame relay network for the voice traffic (feature voice, set fr-net).
5. Add dial matching rules for the telephones attached to the other 2212 (feature
voice, add dial).
6. Add call processing rules for each voice port to go to both phones at the other
2212. Remember to use the same subchannels on both routers. (feature
voice, add call).
7. Enable bandwidth reservation on the frame relay interface and the DLCI. You
will need to reset the router (or the frame relay interface) to further configure
BRS.
8. Set the priority of the voice traffic to urgent on the DLCI.
9. Write and restart.
4.2.2.7 Sample Configuration Steps for 2212 B1
1. To configure Frame Relay interface:
This is a continuation of the configuration from the previous scenario. First we
will configure the frame relay interface and enable end-to-end fragmentation
and the CIR monitor. Since we are in a back-to-back configuration, we need to
disable LMI and add a PVC.
2. To configure voice function:
