Abstract
Systems, methods, and computer program products are provided for controlling calls and monitoring resource status for turret systems. A SIP message including at least one of a header field and an event package is received from a SIP user agent over a communication network. The header field includes a first parameter corresponding to a first call feature and the event package includes a second parameter corresponding to a second call feature. At least one of the first call feature and the second call feature is implemented by the softswitch or a SIP-enabled turret in response to the receiving.
Claims18
A method for controlling calls and monitoring resource status for turret systems, the method comprising the steps of:
- receiving, from a SIP user agent over a communication network, a SIP message including at least one of a header field and an event package, the header field including a first parameter corresponding to a first call feature, the event package including a second parameter corresponding to a second call feature;
- and
- implementing, by a softswitch or a SIP-enabled turret, at least one of the first call feature and the second call feature in response to the receiving.
A computer-readable medium having stored thereon sequences of instructions, the sequences of instructions including instructions, which, when executed by a computer system, cause the computer system to:
- receive, from a SIP user agent over a communication network, a SIP message including at least one of a header field and an event package, the header field including a first parameter corresponding to a first call feature, the event package including a second parameter corresponding to a second call feature;
- and
- implement, by a softswitch or a SIP-enabled turret, at least one of the first call feature and the second call feature in response to the receiving.
A turret call control and resource status monitoring system, the system comprising:
- a softswitch or a SIP-enabled turret including a memory coupled to a processor, wherein the processor is configured to:
- receive, from a SIP user agent over a communication network, a SIP message including at least one of a header field and an event package, the header field including a first parameter corresponding to a first call feature, the event package including a second parameter corresponding to a second call feature;
- and
- implement at least one of the first call feature and the second call feature in response to the receiving.
