Hi All, We recently encountered an issue in our datacenter where an upstream switch between the CPE and the OpenSIPS server was dropping packets. Obviously for VoIP this is not ideal but it did expose an issue in our configuration.
If the packet dropped was a '183 Session Progress' or a 'Ringing' then the CPE would send the same Invite (exact same packet) to which our server issues a 407 Proxy Auth Required. At which stage the CPE seems to hang up. My question: How can I determine if a call is already in progress for a particular Invite ? Apologies if my terminology is not correct, please let me know if anything does not make sense. I have inherited this system and am still very much learning about SIP and OpenSIPS. Thanks in advance Andrew _______________________________________________ Users mailing list [email protected] http://lists.opensips.org/cgi-bin/mailman/listinfo/users
