Hi all, As part of our application, there is a need to shutdown the SIP endpoint during configuration changes (Hostname / IP Address / Port etc...). The simplified steps to handle re-configuration are: 1. pjsip_endpt_destroy() 2. Configuration update. 3. pjsip_endpt_create() 4. Initialize modules (100rel timer etc...) The issue I have noticed is that the capabilities of the endpoint (pjsip_endpt_get_capability()) for the Supported headers will *not* be updated due to static initialization within certain modules (i.e replaces, timer) stopping calls to pjsip_endpt_add_capability(). So outgoing INVITE and outgoing OPTIONS Supported header will *not* include all supported features of the endpoint. Perhaps others have come across a way to handle changes to IP? -- BRgds, Steve King Design Engineer Zetron Australasia
