Fast connection
Network requirements
As shown in Figure 7, phone users of Router A and Router B communicate with each other over WAN. The connection from Router A to Router B adopts fast connection and DTMF H.225 out-of-band transmission. The connection from Router B to Router A adopts DTMF out-of-band transmission and fast connection.

Configuration procedure
Routing-related configurations are beyond the scope of this example. This example assumes that Router A and Router B are reachable to each other.
Configure Router A:
# Configure a VoIP voice entity.
<RouterA> system-view [RouterA] voice-setup [RouterA-voice] dial-program [RouterA-voice-dial] entity 0755 voip [RouterA-voice-dial-entity755] match-template 0755.... [RouterA-voice-dial-entity755] address ip 2.2.2.2
# Enable fast connection, tunnel function and DTMF H.225 out-of-band transmission for the VoIP voice entity.
[RouterA-voice-dial-entity755] fast-connect [RouterA-voice-dial-entity755] tunnel-on [RouterA-voice-dial-entity755] outband h245 [RouterA-voice-dial-entity755] quit
# Configure the local interface and phone number for Telephone A.
[RouterA-voice-dial] entity 1001 pots [RouterA-voice-dial-entity1001] match-template 0101001 [RouterA-voice-dial-entity1001] line 1/1
# Enable out-of-band DTMF transmission for the POTS voice entity.
[RouterA-voice-dial-entity1001] outband h225
Configure Router B:
# Configure the VoIP voice entity.
<RouterB> system-view [RouterB] voice-setup [RouterB-voice] dial-program [RouterB-voice-dial] entity 010 voip [RouterB-voice-dial-entity10] match-template 010.... [RouterB-voice-dial-entity10] address ip 1.1.1.1
# Enable out-of-band DTMF transmission for the VoIP voice entity.
[RouterB-voice-dial-entity10] outband h225 [RouterB-voice-dial-entity10] quit
# Configure the local interface and phone number for Telephone B.
[RouterB-voice-dial] entity 2001 pots [RouterB-voice-dial-entity2001] match-template 07552001 [RouterB-voice-dial-entity2001] line 1/1
# Enable out-of-band DTMF transmission for the POTS voice entity.
