Sorry, I've sent last mail without finishing :) https://kamailio.org/docs/modules/5.5.x/modules/sipdump.html You only have to load the module and set: modparam("sipdump", "enable", 1) Also you can enable or disable using RPC commands: kamcmd sipdump.enable kamcmd sipdump.enable 1 kamcmd sipdump.enable 0 Regards On Tue, 1 Sep 2020 at 13:37, Pepelux &lt;pepeluxx(a)gmail.com&gt; wrote: > Hi > > https://kamailio.org/docs/modules/5.5.x/modules/sipdump.html > > You only have to load the module and set: > > modparam("sipdump", "enable", 1) > > kamcmd sipdump.enable 1 > kamcmd sipdump.enable 0 > > modparam("sipdump", "enable", 1) > > > On Tue, 1 Sep 2020 at 13:23, sip user &lt;sipuser404(a)gmail.com&gt; wrote: > >> Hi Daniel.. >> >> And how load sipdump? >> I'm using kamailio 5.2.1-1 and I think sipdump module is not >> available, right? >> >> Thanks >> >> El mar., 1 sept. 2020 a las 12:27, Daniel-Constantin Mierla (< >> miconda(a)gmail.com&gt;) escribió: >> >>> Hello, >>> >>> it seems that the ACK comes in, but my guess is that the R-URI is >>> not properly set.
