[SR-Users] Re: TM max_inv_lifetime being reset by downstream responses

I have this problem today: SIP-180 responses from downstream apparently reset max_inv_lifetime, and the transaction can live for hours (apparently indefinitely) even though max_inv_lifetime is set to just over a minute. By spacing the SIP-180 responses (from downstream) slightly longer apart than than max_inv_lifetime in kamailio, I don't get the problem, so it looks to me that this is TM not matching what's in the documentation (which mentions that this should be a hard limit). With this configuration, SIP-180 responses every minute result in the transaction never ending (until the client CANCELs the call). - kamailio.cfg:modparam("tm", "fr_timer", 3000) - kamailio.cfg:modparam("tm", "fr_inv_timer", 300000) - kamailio.cfg:modparam("tm", "max_inv_lifetime", 65000) - kamailio.cfg:modparam("tm", "noisy_ctimer", 1) That other thread ends with Daniel mentioning that he'd have to look at the code, but nothing further. Running "git log --grep max_inv_lifetime" shows me that the last/only update that wasn't just documentation was in 2007. Has anyone got an ideas?
