Re: [SR-Users] Time elapsed since previous message.

Hi, You can store the timestamp of the last message of interest in a transaction-persistent variable - that is, an AVP or XAVP - using $TV(): https://www.kamailio.org/wiki/cookbooks/5.4.x/pseudovariables#tv_name Then, you can do some arithmetic like this to turn the difference between two timestamps into milliseconds. This is stolen straight from CSRP so adapt to your needs. :-) # Log request processing time. $var(cur_time) = $TV(Sn); $var(proc_diff) = ( ((( $(var(cur_time){s.select,0,.}{s.int}) - $(avp(proc_start){s.select,0,.}{s.int}) ) * 1000000) + ( $(var(cur_time){s.select,1,.}{s.int}) - $(avp(proc_start){s.select,1,.}{s.int}) ) / 1000) mod 1000 ); — Alex — Sent from my iPad On Feb 9, 2021, at 9:40 AM, David Villasmil < david.villasmil.work(a)gmail.com&gt; wrote: Hello all, Is it possible to know the elapsed time since the previously received message? On outgoing calls, I.e: when i get a 180, how long did the 100 arrived? Or the INVITE...
