Abstract
Systems, methods, and devices of the various embodiments disclosed herein may enable automatic retry of Internet Protocol (IP) Multimedia Subsystem (IMS) Based Session Initiation Protocol (SIP) Call Setup. Various embodiments may enable a server in an IMS based telecommunication network, such as a proxy-call session control function (P-CSCF) server, interrogating/serving-call session control function (I/S-CSCF) server, telephony application server (TAS), etc., to reattempt SIP call setup. In various embodiments, in response to receiving a SIP error response including a retry-after header, the server may wait a period of time before sending a new SIP invite message.
