[kamailio/kamailio] [FEATURE REQUEST] - Add RTT metric to usrloc for measuring subscriber latency (#2223)

by Joel Serrano

## Description ### Add RTT metric to usrloc for measuring subscriber latency This has been discussed several times in the mailing list. As I personally need this too I though it would be a good idea to open this issue for tracking. Unfortunately I'm not aware of the complexity of implementing this and I cannot code it myself, I'm happy to do any testing though or help with any other tasks. Some threads were this has been commented and some solutions proposed by @miconda: https://lists.kamailio.org/pipermail/sr-users/2015-April/088031.html (1st post, see complete thread) https://lists.kamailio.org/pipermail/sr-users/2019-January/104291.html (1st post, see complete thread) Thanks! -- You are receiving this because you are subscribed to this thread.
