Session Manager anti-looping creates a model that is an effective barrier to looping, efficiently identifying a loop condition by maintaining temporary individual call counters for header sets within temporal parameters and terminating the loop condition upon detection. The system provides an administrator with adjustable parameters for loop detection count and loop detection interval, thereby allowing protection against loop conditions, both inadvertent and intentional.

Session manager anti-looping

An initial SIP message is sent to establish a first SIP communication session from a first SIP device. The initial SIP message is sent via a first of a plurality of session managers to a second SIP device. After receiving the initial SIP message at the second SIP device and before ending the first SIP communication session, either the first or second SIP device sends a second SIP message. The second SIP message is sent to the first of the plurality of session managers. Either the first or second SIP devices detects that a response SIP message to the sent second SIP message was not received within a defined time period. In response to detecting that the SIP response message was not received within the defined time period, either the first or second SIP device resends the second SIP message to a second one of the plurality of session managers.

System and method of failover for an initiated SIP session

In one embodiment, a communication device includes an outgoing call alerting agentthat (i) detects that a communication device has entered an off-hook state and that a first line appearance has been selected by a user for an outgoing call, (ii) forwards a first call setup message to a third party call controller, the call setup message including a request to reserve the first line appearance for the outgoing call, and (iii) thereafter collects a set of digits dialed by the user for the outgoing call and provides the collected set of digits to the third party call controller.

Line appearance reservation for SIP endpoints

The present invention is directed to an architecturefor setting up a communication between first and second communication devicesand, the first communication devicecorresponding to a first directing serverand first communication managerseparate from the first directing server, comprising a contact servicing agentoperable to (a) receive a call set up message at least one of addressed to and originated by the first communication device; (b) determine that the first communication devicehas a corresponding first communication manager; (c) forward the call set up message to the first communication managerand request the first communication managerto perform at least one of call originating and terminating processing; and (d) rout the call set up message to a destination referenced in the call set up message.
