These devices send IP signaling directly to the soft-switch, and send their voice and video traﬃc directly to the IP network.
Henry, however, looked at me with withering contempt. “Almost all of that is wrong,” he said. “The phone does NOT ring at that point, because there is a whole load of resource reservation to do ﬁrst. The two terminals have a wonderful time exchanging still more messages to agree on codecs and bandwidth, and to reserve resources in the network, before anyone dares to alert the called party that maybe there is a call for them. The network drowns in messages. ” “Henry, you know and I know that the speciﬁcations for setting up a call in IMS run to dozens of pages—there is no point drowning in detail when Anton here just wants to know how it works.

It has a sophisticated protection architecture: if there is a ﬁber failure or equipment malfunction, this can be detected and the traﬃc switched around the problem in less than 50 milliseconds—unnoticeable in a voice conversation. As a synchronous network, very precise timing information is distributed all around the network, and can be read oﬀ the SONET/SDH line systems.
