PBX对接R2收号限制导致不通案例

PBX对接R2收号限制导致不通案例

1、             组网：

  

 

 

 

 

 

 

 

Pbx内线号码：8007，出局后加前缀0351，变成03518007。

Cisco3640带fxs语音模块，电话号码为03551000。

Cisco3640通过以太网e0接我们的r3640e的e0，r3640e通过v1e1接pbx程控交换机，交换机在接一部电话8007。

2、             问题描述：

从pbx的8007打电话到cisco的03551000正常，但是从cisco下接的03551000电话拨号03518007打到pbx 的8007，不通无振铃音。

 

3、             分析过程：

 

配置见后面附件。

 

当cisco下接的电话拨打pbx上电话时，从deb信息来看语音的数据包到了路由器，排除网络不通的情况，而且路由器也处理了语音数据，有h225协议交互信息，而且也发送了CallProceeding消息，但是协议协商不起来，Send ReleaseComplete Msg when receive CCRelease Msg，问题应该出现在3640e和pbx相接的v1e1线路协商上，详情见下面的deb信息。

由以上信息可以断定pbx接受被叫号码的位数是不是有限制？通过下面的debug信息就可以清楚的解释了。

 

将3640e上的语音配置match-template 0351。。。。 改成match-template  。。。。。。。。debug信息如下：

 

注意这次的主叫号码变为12345678。

总 结

由此可以看出，当pbx走e1语音中继线时，可以通过设置限制接受多少位电话号码，在我们做类似调试的时候注意一下就可以了，不行通过deb voic r2 all 可以清晰看到相关信息。另外这次调试搞到一份pbx程控交换机的说明书，发过来大家可以借鉴一下。
