一、基于 SIP 的 VoIP 通话

1.1 什么是基于 SIP 的 VoIP 通话

使用 SIP（会话初始协议）作为信令协议，在 IP 网络上建立、管理并终止的实时语音（或视频）通话。

SIP（会话初始协议）通话是一套为多媒体会话“铺路架桥”的标准化信令。它的核心价值不在于传输语音本身，而是专注于高效、灵活地建立、管理和结束一个通信会话。
RTP 传输媒体：一旦通话建立，双方的语音/视频数据包通过 RTP 协议直接（或经过媒体代理）发送给对方。

这种分离的架构，使得基于 SIP 的 VoIP 系统具备高灵活性、低成本、易扩展的特点，是当今企业通信、运营商网络（VoLTE）、呼叫中心、云通信等领域的事实标准。

1.2 核心工作机制

一次通话可以拆解为用户注册、呼叫建立、媒体协商、媒体传输、呼叫终止 五个环节。

用户注册：终端向服务器注册；服务器验证身份；目的是让服务器知道用户当前的 IP 地址和端口
呼叫建立：首先是主叫发起呼叫(INVITE)，SIP 代理服务器将 INVITE 消息转发到被叫，消息中携带 SDP（媒体协商：双方协商 RTP 的接收 IP、端口、编解码器、打包时长、媒体方向等）；然后是三次握手 ①180 ringing：被叫端振铃，主叫听到回铃音 ②200 OK：被叫接听，返回 SDP 应答，确认使用的编解码器、媒体接收地址等 ③ACK：主叫确认收到 200 OK，会话正式建立。
媒体传输：会话建立之后，双方就开始使用 RTP（实时传输协议）直接发送媒体包。
呼叫终止：任一方挂断时，发送 BYE 请求，对方回复 200 OK，双方停止 RTP 流，释放信令对话和媒体资源。

1.3 主要优势

开放标准与互操作性：SIP 由 IETF 标准化（RFC 3261），不同厂商的设备（如 IP 话机、软电话、网关、服务器）都能互联互通，企业无需绑定单一供应商，显著降低了硬件采购和系统集成的成本。
信令与媒体分离：SIP 只负责呼叫建立、管理和拆除，而实际的语音/视频数据由 RTP 协议在终端之间直接传输（或经媒体代理）。这种解耦架构让媒体流不必经过 SIP 服务器，从而减少延迟、节省带宽，并避免服务器成为性能瓶颈。
灵活的扩展能力：SIP 基于文本的格式类似 HTTP，易于增加新方法（如 REFER、INFO）或头域，可轻松支持呼叫转接、会议、保持/恢复、即时消息、在线状态等补充业务，适应从企业通信到运营商网络的各种需求。
移动性与漫游支持：用户可在任何有互联网接入的地方（办公室、家庭、酒店、4G/5G）登录同一个 SIP 账号。注册服务器自动记录当前位置，来电能准确送达，实现“号随人走”，特别适合远程办公和多分支机构场景。
成本优势：基于 SIP 的 VoIP 系统可以使用通用的 Linux 服务器和开源软件（如 Asterisk、FreeSWITCH、Kamailio）搭建，无需昂贵的老式程控交换机，且语音流量通过互联网传输（SIP Trunk），大幅降低长途和本地通话费用。

1.4 典型应用场景

SIP 门禁/门铃：访客按铃后通过 SIP 呼叫业主手机或室内分机，可远程可视对讲并开锁。
SIP 广播喇叭：在校园、工厂、地铁站等场所，通过 SIP 协议实现分区广播、定时打铃、应急疏散语音播报。
SIP 电梯电话：电梯内紧急呼叫按钮直连 SIP 网关或 IP 话机，自动拨打物业或救援中心，支持免提对讲。
SIP 报警柱/对讲柱：安装在停车场、公园、景区，遇到紧急情况一键呼叫监控中心，实现双向语音通话。
SIP 调度台：用于公安、机场、矿山等指挥调度系统，可一键呼叫多个 SIP 终端，支持群组对讲、录音、强插等功能。
SIP 会议麦克风/音视频会议终端：基于 SIP 协议加入企业电话会议或视频会议，与传统电话系统互通。
SIP 传感器/紧急按钮：老人或病人按下按钮后，自动向预设的 SIP 号码（如护工手机）发起呼叫，并推送位置和病历信息

依托 SIP 协议的标准化、IP 网络化和易融合特性，可以实现跨厂商、跨系统的音视频通信与联动控制。

二、演示功能概述

单网卡测试 sip 功能：4g 联网测试 sip 功能、以太网联网测试 sip 功能；
多网卡测试 sip 功能：4g 联网 + 以太网联网测试 sip 功能

本文使用 Air780EHV 开发板，分别演示 4g 联网测试、以太网联网测试和多网卡组合测试 sip 功能。

场景一：4g 单网卡联网测试

网络设备驱动模块：根据选择的网络类型在 netdrv_device.lua 文件中加载对应的网络驱动，这里选择 4g 驱动（require "netdrv_4g"）。
音频设备初始化与控制：使用 exaudio.setup 统一配置 ES8311 音频编解码芯片和扬声器功放，包括 I2C、I2S 接口设置及音量控制。
拨号/接听：在无来电的情况下，单击 boot 键进行拨号；收到来电，单击 boot 键进行接听
挂断：来电/拨号/通话过程中，单击 PWRKEY 键进行挂断

场景二：以太网单网卡联网测试

网络设备驱动模块：根据选择的网络类型在 netdrv_device.lua 文件中加载对应的网络驱动，这里选择以太网驱动（require "netdrv_eth_spi"）。
音频设备初始化与控制：使用 exaudio.setup 统一配置 ES8311 音频编解码芯片和扬声器功放，包括 I2C、I2S 接口设置及音量控制。
拨号/接听：在无来电的情况下，单击 boot 键进行拨号；收到来电，单击 boot 键进行接听
挂断：来电/拨号/通话过程中，单击 PWRKEY 键进行挂断

场景三：多网卡联网组合通话测试

网络设备驱动模块：根据选择的网络类型加载对应的网络驱动，这里选择多网融合驱动（require "netdrv_multiple"）。
音频设备初始化与控制：使用 exaudio.setup 统一配置 ES8311 音频编解码芯片和扬声器功放，包括 I2C、I2S 接口设置及音量控制。
拨号/接听：在无来电的情况下，单击 boot 键进行拨号；收到来电，单击 boot 键进行接听
通话保持：当前配置的网络优先级是：以太网 > 4g；先断开以太网，用 4g 联网注册 SIP，在通话过程中连接以太网，通话能够继续保持，通话结束后，下次重新发起 SIP 通话时，会使用当时优先级最高并且网络状态就绪的网卡重新注册。
挂断：来电/拨号/通话过程中，单击 PWRKEY 键进行挂断

三、准备硬件环境

参考：硬件环境清单第二章节内容，准备，并组装好硬件环境。

Air780EHV 开发板一块 +SIM 卡一张 +4g 天线一根 + 网线一根，所有硬件环境组装好，实际测试根据需要进行，具体可以参考”演示核心步骤“中的对应操作。
TYPE-C USB 数据线一根，Air780EHV 开发板和数据线的硬件接线方式为：
Air780EHV 开发板通过 TYPE-C USB 口供电；
TYPE-C USB 数据线直接插到核心板的 TYPE-C USB 座子，另外一端连接电脑 USB 口；

Air780EHV核心板购买链接：合宙Air780EHV核心板内置Audio Codec 支持VoLTE/TTS-淘宝网

四、准备软件环境

4.1 工具 + 内核固件 + 脚本

烧录工具 Luatools；
Air780EHV V2034 及以上版本固件，除 11/12/14 和 111/112/114 固件以外，其他均可，如果需要 TTS 播放，则只能选 1/3/5/7/13/16和101/103/105/107/113Air780EHV 固件；本 demo 开发测试时使用的固件为 Air780EHV V2034 版本固件，如果发现最新版本的内核固件测试有问题，可以使用我们开发本 demo 时使用的内核固件版本来对比测试；
luatos 需要的脚本和资源文件
脚本和资源文件点我浏览所有文件
准备好软件环境之后，接下来查看如何使用 LuaTools 烧录软件，将本篇文章中演示使用的项目文件烧录到 Air780EHV 开发板中，或者查看 Air780EHV 整机开发板使用说明_V1.4 ，将本篇文章中演示使用的项目文件烧录到 Air780EHV 开发板中。
lib 脚本文件：使用 Luatools 烧录时，勾选添加默认 lib 选项，使用默认 lib 脚本文件，如果测试有问题，尝试手动添加 libs（..\LuatOS\script\libs）;

五、代码演示

程序架构

sip/
├── main.lua：主程序入口，加载网络驱动模块、SIP通话模块和按键处理
├── sip_app/
│   ├── sip_app_main.lua：sip主入口;
│   ├── sip_app_key.lua：按键相关处理;
├── netdrv/
│   ├── netdrv_4g.lua：4g网络模块
│   ├── netdrv_eth_spi.lua：“通过SPI外挂CH390H芯片的以太网卡”驱动模块
│   ├── netdrv_multiple.lua：多网卡（4G网卡、通过SPI外挂CH390H芯片的以太网卡）驱动模块
├── netdrv_device.lua：网络设备驱动模块，根据选择的网络类型加载对应的网络驱动
├── audio_drv.lua: 管理音频设备初始化与控制

当前我们有测试账号 100000 和 100001，如果您有自己的 SIP 服务器，那么只需要更改 sip_app_main.lua 文件中 SIP_CONFIG 相关参数和 sip_app_key.lua 的目标号码

local SIP_CONFIG = 
{
    sip_server_addr = "180.152.6.34",
    sip_server_port = 8910,
    sip_domain = "180.152.6.34",
    sip_username = "100000",
    sip_password = "Mm123.",
    _-- sip_username = "100001",_
    _-- sip_password = "Mm123..",_
    sip_transport = exsip.TRANSPORT_UDP,
    auto_answer = false,
}

local function **boot_key_handler**()
    log.**info**(g_tag, "按下BOOT键")
    ...

    sys.**publish**("SIP_APP_MAIN_DIAL_REQ", g_tag, "100001")
end

六、功能演示

1、搭建好硬件环境

2、在 netdrv_device.lua 中选择要测试的网卡场景:

场景一：4g 联网测试：require "netdrv_4g"
场景二：以太网联网测试：require "netdrv_eth_spi"
场景三：多网卡联网测试：require "netdrv_multiple"

3、在 sip_app_main.lua 中的 SIP_CONFIG 配置 SIP 服务器地址，端口，域名，用户名，密码，注意：服务器地址、端口、用户名和密码按实际填，在 sip_app_key.lua 中的 boo 按键函数发布的消息中填写要拨打的号码：sys.publish("SIP_APP_MAIN_DIAL_REQ", g_tag, targetnumber)，本例中 targetnumber = "100001"；

4、打开 MicroSIP/Linphone，输入 sip_app_main.lua 中 SIP_CONFIG 配置的 sip 服务器地址，端口，域名，注意：用户名和密码按实际填，不要与脚本中的用户名重复，本例中 MicroSIP/Linphone 填写的用户名为 100001；

5、烧录内核固件和 sip 相关 demo 成功后，自动开机运行；

6、运行程序，观察日志输出了解系统状态

注意：多网融合情况下的 SIP 通话测试，只有在非/来电/拨号/通话状态下，才会切换到高优先级的网卡重新注册

七、总结

至此，我们通过 Air780EHV整机开发板演示了在不同网络状态下的拨号，来电、通话、网络切换通话保持全过程，动手试一试吧：

来电：来电时播报来电号码，单击 boot 键接听，单击 PWRKEY 拒接
拨号：在无来电的情况下，单击 boot 拨号，拨号过程中可以单击 PWRKEY 取消拨号
网络切换通话保持：通话过程中出现网络切换不影响通话
