Direct Inward Dial (DID) One-Stage Dialing With Direct Inward Dial enabled on POTS dial-peers, the inbound messaging can contain all the digits necessary to route the call. The Cisco Gateway cannot do subsequent digit collection. When the router or gateway searches for an outbound dial-peer, the device uses the entire incoming dial string. This matching is variable-length by default. This match is not done digit-by-digit because by DID definition, all digits have been received. This is the default configuration for POTS dial-peers.
