Hello, my question concerns one test model of mine.
It is basically UAC(SIPp) - SIP proxy(OpenSIPS) - UAS(SIPp) model used for a basic INVITE-ACK-BYE scenario that is used with two kind of security mechanisms: authentication and TLS. My goal is to determine the impact of each of these two mechanisms on the capacity of the model. Last year I was using OpenSIPS version 1.6 and I got results in which number of failed calls was decisive criterion in assessing capacity of test model in all four possible options (w/o TLS and auth, w/o TLS and auth., w/o TLS and with auth. and with TLS and with auth.). But now, after I have upgraded OpenSIPS to version 1.8 the situation is different. Not only that the capacity of the model is lower now in all four scenarios, but also Opensips crashes under not so heavy traffic when using TLS (it worked just fine with a heavier load when using 1.6 version). I am a little bit puzzled because I haven't change anything else in the model, at least I am not aware of that. Do you know are there some stability issues in OpenSIPS 1.8 when used together with TLS? Thanks, Tarik
