VOIP业务路由器R2620升级案例

VOIP业务路由器升级案例

问题描述：

某局点两台R2620路由器通过2M串口线路对接，（一个在中心局点，一个在远端局点）实现数据通讯和VOIP业务。曾经使用VRP1.5.6 Realese (1)版本，由于业务安全需要，升级至VRP1.74-0105版本。

升级过程正常，当中心局点路由器升级至VRP1.74-0105版本后，数据业务正常，VOIP业务无法工作；再升级远端路由器后，数据业务正常，VOIP业务仍旧不正常，中心局点可以作为主叫，被叫不通。远端局点称听不到回铃音，本端局点也没有振铃。

组网情况：

解决措施：

根据对网络情况的理解，分析了号码匹配的规则，

配置match-template .T

或者match-template T

或者match-template 0 ，故障现象都一致。

配置了match-template 0T后，故障消失，“disp cur”时，显示为 “match-template 0T”。

后来发现在VRP1.5.6中显示的两条命令也是配置 “destination-pattern 0T”产生的，只是”show run”的时候，显示为两条。
