    摘要： Techniques are disclosed for call failover in a communication protocol for facilitating establishment of communication sessions between devices. For example, a method for maintaining, in the presence of a failure, an existing communication session between a first communication device and a second communication device in a communication system, wherein the communication session is established in accordance with an original signaling path between the first communication device and the second communication device, includes the following steps. Occurrence of a failure in the communication system is determined. An alternate signaling path is established between the first communication device and the second communication device such that the first communication device and the second communication device can continue the existing communication session using the alternate signaling path. When the communication session is conducted in accordance with a Session Initiation Protocol (SIP), the message sent to initiate establishment of the alternate signaling path may be an INVITE message with a Replaces header.

    摘要： A business performs a credit check on a customer's credit card number by utilizing the D-channel of an Integrated Services Digital Network (ISDN) facility. The ISDN facility connects the business to a telecommunications network, which utilizes signaling system number 7 (SS7). Specifically, the ISDN Q.931 protocol is modified to allow the Q.931 FACILITY message to include: a) credit check request, b) a call reference number, and c) the customer's credit card number. This information is sent, via the ISDN D-channel, to the telecommunications network, which passes the information, via an SS7 Transaction Capability Application Part (TCAP) message, to a credit checking data base. A result from the credit checking data based is then passed back through the telecommunications network to the business on the D-channel of the ISDN facility.
