VG语音实体相关的号码变换

语音实体相关的号码变换

一、组网需求：

北京和上海各有一个由PBX组成的本地电话网，利用两台语音网关实现互通， PBX内部用户可以通过VoIP拨打异地的普通电话。

在北京和上海都有财务部、市场部和销售部。在这些部门，本地拨打本地的电话，只需要拨打内部短号，而拨打外地部门电话，需要拨打长号。例如，上海的财务部打市场部，拨3366。上海的财务部打北京的市场部，拨0106788即可接通，而北京的市场部来电显示为0211688，即上海区号+上海财务部电话号码。

在各地语音网关用户线对应的pots实体配置的都是短号。

三、配置步骤：

1.     上海语音网关的配置：

# 配置以太口地址为 2.2.2.2

[VGA] interface

[VGA-if] ether 0

[VGA-if-eth0] address ip 2.2.2.2

# 配置本地用户线号码

[VGA] voice-setup

[VGA-voice] dial-program

[VGA-voice-dial] entity 20 pots

[VGA-voice-dial-entity 20] match-template 2323

[VGA-voice-dial-entity 20] line 0

[VGA-voice-dial] entity 21 pots

[VGA-voice-dial-entity 21] match-template 1688

[VGA-voice-dial-entity 21] line 1

[VGA-voice-dial] entity 22 pots

[VGA-voice-dial-entity 22] match-template 3366

[VGA-voice-dial-entity 22] line 2

# 配置被叫号码变换表：

[VGA-voice-dial] number-substitute 1

[VGA-voice-dial-subst1] rule 1 ^010....$ ....

# 配置主叫号码变换表：

[VGA-voice-dial-subst2] quit

[VGA-voice-dial] number-substitute 2

[VGA-voice-dial-subst2] rule 1 1688 0211688

[VGA-voice-dial-subst2] rule 2 3366 0213366

[VGA-voice-dial-subst2] rule 3 2323 0212323

# 配置上海到北京的VoIP语音实体。

[VGA-voice-dial-subst2] quit

[VGA-voice-dial] entity 10 voip

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

[VGA-voice-dial-entity10] address ip 1.1.1.1

# 配置上海到北京的VoIP语音实体的号码变换规则

[VGA-voice-dial-entity10] substitute called 1

[VGA-voice-dial-entity10] substitute calling 2

2.     北京语音网关的配置：

# 配置以太口地址为 1.1.1.1

[VGB] interface

[VGB-if] ether 0

[VGB-if-eth0] address ip 1.1.1.1

# 配置本地用户线号码

[VGB] voice-setup

[VGB-voice] dial-program

[VGB-voice-dial] entity 20 pots

[VGB-voice-dial-entity 20] match-template 1234

[VGB-voice-dial-entity 20] line 0

[VGB-voice-dial] entity 21 pots

[VGB-voice-dial-entity 21] match-template 6788

[VGB-voice-dial-entity 21] line 1

[VGB-voice-dial] entity 22 pots

[VGB-voice-dial-entity 22] match-template 6565

[VGB-voice-dial-entity 22] line 2

# 配置被叫号码变换表：

[VGB-voice-dial] number-substitute 1

[VGB-voice-dial-subst101] rule 1 ^1234$ 0101234

[VGB-voice-dial-subst101] rule 2 ^6788$ 0106788

[VGB-voice-dial-subst101] rule 3 ^6565$ 0106565

# 配置主叫号码变换表：

[VGB-voice-dial-subst101] quit

[VGB-voice-dial] number-substitute 2

[VGB-voice-dial-subst102] rule 1 ^021....$ 021....

# 配置北京到上海的VoIP语音实体：

[VGB-voice-dial-subst102] quit

[VGB-voice-dial] entity 10 voip

[VGB-voice-dial-entity10] match-template 021….

[VGB-voice-dial-entity10] address ip 2.2.2.2

# 配置北京到上海的VoIP语音实体的号码变换规则

[VGB-voice-dial-entity10] substitute calling 1

[VGB-voice-dial-entity10] substitute called 2

四、配置关键点：

首先使用number-substitute定义了号码变换的规则，然后在对应的语音实体视图下使用substitute绑定号码变换规则。注意：语音实体下的号码变换规则是匹配了语音实体以后的变换规则，所以不存在in和out的概念。
