Voice entity configuration example for establishing a VoIP call

As shown in Figure 6, two voice gateways (Router A and Router B) communicate with each other through WAN.

For example, the user of tel. 1 (010-1001) attached to Router A dials 0755-2001, the number of tel. 3 attached to Router B. After the called party picks up the phone, a conversation is established between two parties.

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 the VoIP voice entity to Router B.

   <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 sip ip 2.2.2.2
   [RouterA-voice-dial-entity755] quit
   

   # Configure the POTS voice entity corresponding to the local interface Line 1/0.

   [RouterA-voice-dial] entity 1001 pots
   [RouterA-voice-dial-entity1001] match-template 0101001
   [RouterA-voice-dial-entity1001] line 1/0 
   [RouterA-voice-dial-entity1001] quit
   

   # Configure the POTS voice entity corresponding to the local interface Line 1/1.

   [RouterA-voice-dial] entity 1002 pots
   [RouterA-voice-dial-entity1002] match-template 0101002
   [RouterA-voice-dial-entity1002] line 1/1
   

2. Configure Router B:

   # Configure the VoIP voice entity to Router A.

   <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 sip ip 1.1.1.1
   [RouterB-voice-dial-entity10] quit
   

   # Configure the POTS voice entity corresponding to the local interface Line 2/0.

   [RouterB-voice-dial] entity 2001 pots
   [RouterB-voice-dial-entity1001] match-template 07552001
   [RouterB-voice-dial-entity1001] line 2/0 
   [RouterB-voice-dial-entity1001] quit
   

   # Configure the POTS voice entity corresponding to the local interface Line 2/1.

   [RouterB-voice-dial] entity 2002 pots
   [RouterB-voice-dial-entity1002] match-template 07552002
   [RouterB-voice-dial-entity1002] line 2/1
