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.

  1. 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
    
  2. 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.

    [RouterB-voice-dial-entity2001] outband h225
