Nortel technical support is probably the best qualified to answer specific questions on the configuration of the ASN Router and its capabilities. In general, you'll also want to look carefully at how many simultaneous calls you are going to make over your WAN links and understand the bandwidth utilization. Also, if there are multiple WAN routes between sites, you'll want to consider failover scenarios and the rerouting of prioritized voice traffic over the remaining links. You must be careful not to end up with scenarios where the bandwidth of a link is exceeded with high priority voice traffic.
