什么是sip strunking？
会话发起协议（sip）是用于对ip（internet协议）网络进行多媒体通信会话的技术标准。 sip和voip有时可互换使用，但它们不一样。 voip - 互联网语音 - 是用于覆盖在互联网上进行的任何语音呼叫的毯子术语。 ip语音使用协议技术来实现此功能，sip是一个启用voip的协议。.
along with being cheaper and easier to scale, sip trunking may help reduce charges from toll-free and long-distance phone calls as they’re being placed over the internet and not on the wired phone network where those sorts of fees typically apply. likewise, businesses can consolidate billing by having their data and voice services on a single ip network instead of being separate.
