Sangoma NSG安装前准备
获得运营商点码OPC/DPC点码
用户在安装Sangoma NSG SS7 设备之前,必须和运营商确认OPC 和DPC的相关信息。确认相关信息以后,提交一个配置文件到sangoma技术支持,sangoma 技术支持会根据配置文件的要求,登录用户设备按照相应的参数进行配置。具体的链接如下: http://wiki.sangoma.com/NSG-Questionnaire
检查运营商物理接口
Sangoma SS7 设备支持75欧姆的接口,官方出厂时不带75欧姆转120欧姆的BNC转接头。所以客户在安装现场确认运营商的接口是哪一种类型,提前准备。具体的线序参考如下: http://wiki.sangoma.com/Cable-Pinouts
Sangoma NSG SS7 支持功能
Sangoma SS7 仅支持ISUP 中国变种,不支持TUP协议,具体支持的协议包括:
- ISUP
- SIP
- RFC 2976 SIP INFO Method
- RFC 3398 ISUP-SIP Mapping
- RFC 3515 Refer Method
- RFC 2327 Session Description Protocol
- RFC 3581 An Extension to the Session Initiation Protocol (SIP) for Symmetric Response Routing
- RFC 3892 Referred-By Mechanism
- RFC 3891 "Replaces" Header
- RFC 3551: RTP/AVP
- RFC 3515: REFER
- RFC 2617: HTTP Digest Authentication
- SDP Bypass
- RFC 3262: PRACK and 100rel *
- RFC 4168: SCTP as Transport for SIP*
Sangoma NSG SS7 安装支持包
Sangoma NSG SS7 支持两种SS7 设备部署形式:1)二进制包安装 2)ISO 光盘安装。
请总是访问Sangoma 官方技术文档来获得最新技术文档,访问地址为Sangoma NSG 技术文档
下载 NSG ISO版本或者二进制包
用户可以从此页面下载安装以后自己需要的文件格式: http://wiki.sangoma.com/NSG-Installation-0
安装ISO 或者二进制包
具体的安装步骤可以根据此链接来进行操作:http://wiki.sangoma.com/NSG-Installation-0
登录NSG 配置界面
如果安装成功,二进制 SS7 软件包安装以后的,NSG SS7的页面为:http://<NSG-IP>:8888
配置E1端口,SS7信令
通常对于中国用户来说,需要配置的参数包括:CRC4,DPC,OPC,拨号属性。关于配置的具体步骤,sangoma 技术人员会协助安装调试,这里我们仅列出一些配置后的截图,一方便用户参考.其中包括了主要的价格步骤:配置E1,配置linkset,配置CIC电路等等,以及如何排查线路状态,具体方法请参考以下链接:
http://www.voip88.com/article-1245-1.html
通过配置E1,linkset 和CIC电路,显示正常的配置状态,例如:
TDM 物理连接,信令状态必须正常,如下截图所示:
中国用户特别注意到是SS7 设置部分,包括对应的中国选项
下载安装FreeSWITCH
用户可以直接下载任何FreeSWITCH的版本进行安装,这里不做介绍。用户可以安装Sangoma 和FreeSWITCH在同一台服务器,但是需要安装二进制SS7 软件包。
注册Sangoma网关
安装FreeSWITCH以后,用户需要配置Sangoma 网关注册信息。在FreeSWITCH 配置sangoma NSG 比较简单,在SIP-profiles 文件夹下 internal.xml 中添加一行代码:
<gateway name="sangoma"> <param name="username" value="sangoma"/> <param name="password" value="sangoma"/> <param name="realm" value="192.168.1.109:5062"/> // samgoma 网关IP地址和端口 <param name="dialplan" value="xml"/> <param name="context" value="from-NSG"/> </gateway>
网关注册以后,可以通过Sangoma SS7 管理界面看到成功注册的信息,例如:
添加拨号规则
1)在default.xml中设置呼入规则:
<context name="from-NSG"> <extension name="incoming_call"> <condition field="destination_number" expression="1111" break="never"> // 呼入号码为1111 <!-- extract the span name from the SIP-X headers --> <action application="set" data="span=${sip_h_X-freetdm-SpanName}"/> <!-- log that we have an incoming call from NSG and which span the call came in on --> <action application="log" data="INFO Incoming call from NSG on span=${span}"/> <action application="set" data="domain_name=$${domain}"/> <action application="transfer" data="1000 XML default"/> // 分机1000 振铃 <!-- answer the call...if this is not run, the "echo" application will run in "early media" --> <action application="answer" data=""/> <!-- use the "echo" application to confirm there is 2 way audio. Delay audio by 1s so that echo cancelers don't cause problems --> <action application="echo" data="1000"/> </condition> </extension> </context>
2) 在public.xml 中设置呼出规则:
<extension name="outgoing_call"> <condition field="destination_number" expression="^1111$" break="never"> <action application="export" data="effective_caller_id_number=9999"/> // 透传 ANI 号码 <action application="bridge" data="sofia/external/${destination_number}@192.168.1.109:5062"/> // 呼出到sangoma SS7 </condition> </extension>
测试呼叫
1)从外部呼入,呼叫号码为1111,呼入到对应的路由,日志为
