3CX SIP Trunk 供应商- 意大利
这些位于意大利的 SIP Trunk 提供商已经过 3CX 的测试与认证。我们强烈建议使用优选或受支持的 SIP Trunk 服务提供商。3CX 团队会确保所列 SIP Trunk 提供商的所有模板在每个版本中都得到更新和测试，从而确保用户不会遇到任何问题。
在托管环境中，基于注册的、无需固定 IP 的中继仍然是首选。这是因为在某些情况下，您由 3CX 托管的系统的公共 IP 可能会发生意外更改。尽管这并不常见，但一旦发生此情况，您将暂时无法通过基于 IP 的中继拨打和接听电话。
请阅读我们的指南：如何配置 SIP Trunk / VoIP 提供商。该指南涵盖了使用 3CX 配置中继所需的一般步骤。部分提供商可能需要特殊的配置要求。在选择您所在地区的 SIP Trunk 提供商之前，请仔细查看我们的列表，了解这些特殊要求，并确保遵循任何附加的配置指南。
