Why do you expect them to match a known transaction? -- Alex On Sat, Mar 28, 2020 at 08:14:05PM +0000, egemen ulus wrote: > Hi All, > > I'm trying to establish a topology with Kamailio which is located between > Asterisk and Outside. > > My issue is "transaction matching failed" (t_check_trans failed).
