SIP中继服务市场 - 全球产业规模、份额、趋势、机会及预测（按组织规模、最终用户、地区和竞争格局划分，2021-2031年）

全球 SIP 中继服务市场预计将从 2025 年的 142.7 亿美元成长到 2031 年的 282.3 亿美元，复合年增长率为 12.04%。

本质上，对话启动协定(SIP) 中继是一种通讯服务，它将公司内部的专用专用交换机(PBX) 透过网际网路连接到公共交换电话网路 (PSTN)，从而有效地取代了传统的固定电话线路。市场成长的主要驱动力是硬体维护成本的显着降低、通道容量的按需扩充性以及全球淘汰老旧模拟基础设施的需求。这种结构性变化在旧有系统的快速衰退中显而易见。例如，英国通讯管理局 (Ofcom) 发布的 2024 年报告预测，随着企业加速向数位语音解决方案转型，传统语音连线将仅占所有固定电话连线的 27%，低于前一年的 41%。

然而，市场扩张面临一个重大障碍：它依赖稳定、高速的网路连线。由于SIP中继透过IP网路传输语音数据，基础设施不稳定的地区的组织经常会遇到服务品质问题，例如延迟和丢包。这些技术难题会影响通讯清晰度，并阻碍SIP解决方案在可靠性至关重要的关键任务环境中的应用。

市场驱动因素

全球从传统公共交换电话网路 (PSTN) 和综合业务数位网路 (ISDN) 系统向 IP 为基础的网路过渡，是推动 SIP 中继服务普及的根本动力。随着通讯业者和监管机构逐步淘汰过时的铜缆基础设施，企业被迫转向数位语音解决方案以维持服务连续性。爱尔兰通讯监管机构 (ComReg) 的数据也印证了这项根本转变。根据该机构发布的《2024 年第一季关键数据报告》，预计 2024 年第一季爱尔兰的固定语音流量将年减 25%，这反映出传统电话系统的快速淘汰。因此，这种强制性过渡催生了对 SIP 中继的迫切需求，SIP 中继是现代基于 IP 的专用交换机(PBX) 系统必不可少的连接层。

同时，基于云端的整合通讯(UC) 服务的快速普及正在改变市场消费模式，将语音服务从本地硬体转移到灵活的云端平台。主要的 UCaaS 供应商现在直接整合公共交换电话网路 (PSTN) 连接，使得强大的 SIP 中继基础设施成为支援大量并发呼叫的关键。例如，微软在 2024 年 4 月发布的 2024 财年第三季财报电话会议上报告称，Teams Phone 的 PSTN 用户数量年增 30%，达到 2,000 万。云端采用率的激增为 SIP 供应商创造了巨大的商机。 Gamma Communications PLC 在 2024 年 3 月发布的 2023 财年年度报告和帐目中报告称，其收入增长 8%，达到 5.217 亿英镑，这主要得益于其企业云语音业务的增长。

市场挑战

对稳定高速网路连线的依赖是全球SIP中继服务市场扩张的主要障碍。与传统电话系统不同，SIP中继将语音讯号封装在数位资料包中，并透过IP网路传输，这使得该服务本身极易受到频宽波动的影响。在数位基础设施欠发达的地区，企业经常面临严重的服务品质问题，例如高延迟、抖动和封包遗失。这些技术缺陷会降低通话清晰度和可靠性，迫使企业宁愿维护昂贵的传统类比系统，也不愿冒险使用不稳定的IP连线进行业务通讯。

对强大网路架构的依赖限制了潜在市场的规模，尤其是在数位落差显着的开发中国家。在底层传输层缺失或不可靠的地区，服务供应商无法有效部署SIP解决方案。根据电讯（ITU）预测，到2024年，全球约有26亿人（占全球人口的32%）将无法连接网路。这种严重的网路连线不足凸显了阻碍SIP服务普及的实体限制，也有效地限制了市场充分发挥其全球潜力。

市场趋势

自带业者 (BYOC) 模式的日益普及正在从根本上改变筹资策略，因为企业正逐步将电话服务与整合通讯即服务 (UCaaS) 平台解耦。这种方法允许企业选择独立的 SIP 中继供应商，同时保留其首选的协作介面，从而更好地控制呼叫路由、合规性和全球覆盖范围。营运商层级的解耦使企业能够协商更优惠的价格、确保冗余，并避免捆绑营运商套餐带来的供应商锁定。这种解耦基础设施的商业性发展势头十分强劲：Bandwidth Inc. 在 2024 年 8 月发布的“2024 财年第二季度”财报中公布，其总收入达 1.74 亿美元，这主要得益于企业云通信和直接运营商集成方面的需求。

同时，部署人工智慧驱动的自动化诈欺侦测系统来保护SIP架构免受国际收入分成诈骗（IRSF）和王吉里攻击等高阶威胁，正成为日益重要的技术挑战。由于传统的静态规则集已无法抵御动态攻击，营运商正在整合机器学习演算法，以驱动即时流量分析，从而在造成经济损失之前检测并阻止异常情况。恶意流量的快速成长进一步凸显了此类高阶防御机制的必要性。根据Hiya于2024年4月发布的《2024年通话状况报告》，2023年处理的所有未知呼叫中，有28%将被判定为诈骗或垃圾电话，这凸显了一个严重的安全风险，而人工智慧增强型SIP解决方案亟需缓解这一风险。

The Global SIP Trunking Services Market is projected to expand from USD 14.27 Billion in 2025 to USD 28.23 Billion by 2031, registering a compound annual growth rate of 12.04%. Essentially, Session Initiation Protocol (SIP) trunking is a communication service that links a company's on-premise private branch exchange (PBX) to the public switched telephone network (PSTN) via the internet, effectively replacing traditional fixed telephone lines. The market's growth is primarily driven by the substantial cost savings realized through the elimination of hardware maintenance, the ability to scale channel capacity on demand, and the global necessity to migrate from outdated analog infrastructure. This structural shift is highlighted by the rapid decline of legacy systems; for example, Ofcom reported in 2024 that legacy voice connections dropped to just 27% of all landline connections, down from 41% the previous year, as enterprises accelerate their transition to digital voice solutions.

However, market expansion faces a significant obstacle regarding the reliance on consistent, high-speed internet connectivity. Since SIP trunking transmits voice data over IP networks, organizations located in regions with unstable infrastructure frequently encounter quality of service issues, such as latency and packet loss. These technical difficulties can compromise communication clarity and discourage the adoption of SIP solutions in environments where mission-critical reliability is essential.

Market Driver

The worldwide transition from legacy PSTN and ISDN systems to IP-based networks serves as the fundamental catalyst for the adoption of SIP trunking services. As telecommunications operators and regulatory bodies decommission obsolete copper infrastructure, enterprises are forced to migrate to digital voice solutions to maintain service continuity. This structural displacement is evident in data from the Commission for Communications Regulation (ComReg), which noted in its 'Quarterly Key Data Report Q1 2024' that fixed voice traffic in Ireland fell by 25% in the first quarter of 2024 compared to the same period in 2023, reflecting the rapid obsolescence of traditional telephony. Consequently, this mandatory migration creates an urgent, non-negotiable demand for SIP trunks as the essential connectivity layer for modern IP-based Private Branch Exchange (PBX) systems.

Simultaneously, the swift proliferation of cloud-based Unified Communications (UC) services is transforming market consumption patterns, moving voice services from on-premise hardware to flexible cloud platforms. Major UCaaS providers are now integrating public switched telephone network (PSTN) connectivity directly, necessitating robust SIP trunking backbones to handle high volumes of concurrent calls. For instance, Microsoft reported in its 'Fiscal Year 2024 Third Quarter Earnings Conference Call' in April 2024 that Teams Phone PSTN users reached 20 million, a 30% increase year-over-year. This surge in cloud adoption generates significant commercial opportunities for SIP providers; Gamma Communications PLC, in its 'Annual Report and Accounts 2023' released in March 2024, reported an 8% revenue increase to £521.7 million, driven largely by growth in their business and enterprise cloud voice segments.

Market Challenge

The dependency on consistent, high-speed internet connectivity presents a formidable barrier to the expansion of the Global SIP Trunking Services Market. Unlike traditional telephony, SIP trunking encapsulates voice signals into digital packets for transmission over IP networks, making the service inherently vulnerable to bandwidth fluctuations. In regions with underdeveloped digital infrastructure, organizations frequently encounter significant quality of service issues, including high latency, jitter, and packet loss. These technical deficiencies degrade call clarity and reliability, compelling enterprises to retain expensive legacy analog systems rather than risking their operational communications on unstable IP connections.

This reliance on robust network architecture restricts the addressable market size, particularly in developing economies where the digital divide remains pronounced. Service providers cannot effectively deploy SIP solutions in areas where the fundamental transport layer is absent or unreliable. According to the International Telecommunication Union, approximately 2.6 billion people remained offline worldwide in 2024, accounting for 32 percent of the global population. This substantial lack of connectivity underscores the physical limitations hindering the universal adoption of SIP services, effectively preventing the market from reaching its full global potential.

Market Trends

The increasing popularity of Bring Your Own Carrier (BYOC) models is fundamentally altering procurement strategies as enterprises progressively unbundle telephony services from Unified Communications as a Service (UCaaS) platforms. This approach allows organizations to select independent SIP trunking providers while maintaining their preferred collaboration interfaces, granting them greater control over call routing, regulatory compliance, and global coverage. By decoupling the carrier layer, businesses can negotiate superior rates and ensure redundancy, avoiding the vendor lock-in associated with bundled carrier plans. The commercial momentum of this unbundled infrastructure is evident; Bandwidth Inc. reported total revenue of $174 million in its 'Second Quarter 2024 Financial Results' in August 2024, a figure driven significantly by the demand for enterprise-grade cloud communications and direct carrier integration.

At the same time, the deployment of AI-driven automated fraud detection systems has become a critical technological imperative to secure SIP architecture against sophisticated threats like International Revenue Share Fraud (IRSF) and Wangiri attacks. Traditional static rule sets are no longer sufficient to stop dynamic attack vectors, prompting providers to integrate machine learning algorithms that analyze traffic patterns in real-time to block anomalies before financial damage occurs. The necessity for these advanced defensive mechanisms is underscored by the escalating volume of malicious traffic; Hiya's '2024 State of the Call Report' from April 2024 noted that 28% of all unknown calls processed in 2023 were identified as fraud or spam, highlighting the severe security risks that AI-enhanced SIP solutions must now mitigate.
