;;;SIP Profile Overview
SIP Profile 是一个SBC的帐号，包含了一系列的SIP配置属性和SBC本身关联。
SIP profile 用来配置如何支持外部的终端连接到SBC设备。
用户绑定一个IP地址，端口和其他相关的功能设置。
用户也同样绑定了call routes, domain profiles, media profiles, 和 SIP trunks，并且关联到SIP profiles。

SIP profile 包含了SIP UA 配置。 
Sangoma SBC 可以配置为一个多 UA 帐号，每个UA 有不同的配置(因此，需要不同的IP:端口组合)。

SIP Profile 描述的信息是相对于SBC的本地信息。
远端用户代理信息用来连接Sangoma SBC。

*本地监听端口
*本地验证用户信息
*本地传输信息: TCP,UDP etc..

;;;SIP Profile Configuration
用户可以创建一个SIP profiles，点击菜单“Configuration -> Signaling -> SIP Profiles”。

使用有含义的SIP profile 名称，无空格，例如“internal”, “internal-network”, “external-users”等等。

 记住SIP profile 是一个 SIP UA ，它用来和其他的SIP UA(例如 SIP phones) 或者 服务器 (ITSP, SIP Proxies )来进行通信。

一旦点击了“Create”，用户会看到一个配置界面来创建新的SIP profile，在这个配置文件中，用户可以设置:
*所有SIP profile信息
*包括IP信息
*TLS/SRTP 设置等等。

需要特别注意以下内容:

SIP Profile Field	Description
IP Address	This is the IP address where NSC will listen for calls
Transport	Most implementations will want to leave the default “UDP+TCP”, this means SIP packets will be accepted in both UDP and TCP protocols.
Port	Most of the time you will want to leave the default 5060 port.
Authenticate Calls	This means any SIP calls (INVITE requests) will be accepted and not challenged.
Routing Plan:	You have to choose the routing plan you created before ()
! Security Note: If you Disable Authenticate Calls in the SBC, take care that the remote SIP UA, eg: IP IPBX has authetication enabled.

! Security Note: if you are exposing a SIP Profile to the public internet, you may want to change its Port to something different than default 5060, in order to reduce attach exposure. 
Many malicious tools scan for for 5060 to find SIP systems connected to the internet. Even though Sangoma SBC comes with several protection mechanisms to detect scans, you will be better off on the internet by using a different port.

*The contextual help on each field will give you information about what each field in the SIP profile does.

When done configuring the SIP profile click “Save”.

You can now proceed to optionally bind one or more domains to this SIP profile. 
When you bind a domain to a SIP profile you are attaching all the user directory of each domain bound for this SIP profile to be able to accept registrations and/or perform authentication of SIP INVITE messages based on the user/password information stored in the domain user directory (or performed via authentication forwarded according to the domain configuration).

*Note that in order to perform SIP authentication you have to set the “Authenticate Calls” parameter to “Enable”.

To bind a domain to a SIP profile simply click “Bind” in the SIP profile modification page:

Then choose the domains you which to bind.

Finally click “Bind”. You will see now the domain listed in the SIP profile page.
