Abstract
An apparatus and method are described for resolving a glare condition between two SIP endpoints. The method allows a third party call control controller to resolve the glare condition when the ownership status of each dialog is the same, by initiating a back-off period of time at the apparatus based on the ownership status of the SIP dialog and re-sending a re-INVITE message to the end point after expiry of the back-off period of time.
