QSIG tunneling configuration example

As shown in Figure 25, connect Router A and Router B each to a PBX through QSIG signaling. The SIP protocol runs between Router A and Router B.

The requirements are as follows:

When a call is placed from 010-1001 to 0755-2001, the ingress gateway Router A encapsulates the received QSIG signaling messages into SIP messages, and sends the SIP messages to the egress gateway Router B over the SIP network. This extracts the QSIG signaling messages from the SIP messages and sends them to the receiving end at the ISDN side.

1. Configure Router A:

   # Configure IP address 1.1.1.1/24 for interface Ethernet 2/1.

   <RouterA> system-view
   [RouterA] interface ethernet 2/1
   [RouterA-Ethernet2/1] ip address 1.1.1.1 255.255.255.0
   [RouterA-Ethernet2/1] quit
   

   # Create an ISDN PRI group on interface E1 1/1.

   [RouterA] system-view
   [RouterA] controller e1 1/1
   [RouterA-E1 1/1] pri-set
   [RouterA-E1 1/1] quit
   

   # Set the ISDN protocol type and protocol mode for the ISDN interface serial 1/1:15.

   [RouterA] interface serial 1/1:15
   [RouterA-Serial1/1:15] isdn protocol-type qsig 
    [RouterA-Serial1/1:15] quit
   

   # Create a POTS voice entity for the ISDN PRI interface.

   [RouterA] voice-setup
   [RouterA-voice] dial-program
   [RouterA-voice-dial] entity 1001 pots
   

   # Configure a target match-template pointing to telephone number 010-1001 for the POTS voice entity.

   [RouterA-voice-dial-entity1001] match-template 0101001
   

   # Associate the POTS voice entity with subscriber line 1/1:15.

   [RouterA-voice-dial-entity1001] line 1/1:15
   [RouterA-voice-dial-entity1001] send-number all
   [RouterA-voice-dial-entity1001] quit
   [RouterA-voice-dial] quit
   [RouterA-voice] quit
   

   # Enable the QSIG tunneling function on the subscriber line associated with the POTS voice entity.

   [RouterA] subscriber-line 1/1:15
   [RouterA-subscriber-line1/1:15] qsig-tunnel enable
   [RouterA-subscriber-line1/1:15] quit
   

   # Create a VoIP voice entity.

   [RouterA-voice] dial-program
   [RouterA-voice-dial] entity 0755 voip
   

   # Configure a target match-template for the VoIP voice entity.

   [RouterA-voice-dial-entity755] match-template 0755....
   

   # Configure the target address of the VoIP voice entity.

   [RouterA-voice-dial-entity755] address sip ip 2.2.2.2
   

2. Configure Router B:

   # Configure the IP address 2.2.2.2/24 for the interface Ethernet 2/1.

   <RouterB> system-view
   [RouterB] interface ethernet 2/1
   [RouterB-Ethernet2/1] ip address 2.2.2.2 255.255.255.0
   [RouterB-Ethernet2/1] quit
   

   # Create an ISDN PRI group on interface E1 1/1.

   [RouterB] controller e1 1/1
   [RouterB-E1 1/1] pri-set
   [RouterB-E1 1/1] quit
   

   # Set the ISDN protocol type and protocol mode for the ISDN interface serial 1/1:15.

   [RouterB] interface serial 1/1:15
   [RouterB-Serial1/1:15] isdn protocol-type qsig 
    [RouterB-Serial1/1:15] quit
   

   # Create a POTS voice entity for the ISDN PRI interface.

   [RouterB] voice-setup
   [RouterB-voice] dial-program
   [RouterB-voice-dial] entity 2001 pots
   

   # Configure a target match-template pointing to telephone number 0755-2001 for the POTS voice entity.

   [RouterB-voice-dial-entity2001] match-template 07552001
   

   # Associate the POTS voice entity with subscriber line 1/1:15.

   [RouterB-voice-dial-entity2001] line 1/1:15
   [RouterB-voice-dial-entity2001] send-number all
   [RouterB-voice-dial-entity2001] quit
   [RouterB-voice-dial] quit
   

   # Enable the QSIG tunneling function on the subscriber line associated with the POTS voice entity.

   [RouterB] subscriber-line 1/1:15
   [RouterB-subscriber-line1/1:15] qsig-tunnel enable
   [RouterB-subscriber-line1/1:15] quit
   

   # Create a VoIP voice entity.

   [RouterB-voice] dial-program
   [RouterB-voice-dial] entity 010 voip
   

   # Configure a target match-template for the VoIP voice entity.

   [RouterB-voice-dial-entity10] match-template 010....
   

   # Configure the target address of the VoIP voice entity.

   [RouterB-voice-dial-entity10] address sip ip 1.1.1.1
