Hi all, In my environment, there are one outbound proxy and one internal SIP server. The outbound proxy is an interface exposed to SIP clients and the internal SIP server is the one handling registration and making calls for SIP clients. For Apple's APNS service, one scenario must be supported in my environment (refer to my previous thread http://opensips-open-sip-server.1449251.n2.nabble.com/What-variable-mechanism-is-applicable-to-a-not-yet-transaction-case-td7586962.html).
The scenario is that the outbound proxy will repeatedly send INVITEs to the SIP server on behalf of the caller before the callee has registered successfully. During the process, the SIP server "sometimes" thinks the repeated INVITEs with stale nonce and asks for authentication again. Since the repeated INVITEs are sent in less than 10 seconds after the first INVITE, the nonce should remain valid (the default nonce_expire_time is 30 seconds in OpenSIPS). Has anyone encountered the same issue? Any help is greatly appreciated.
