[SR-Users] RTPEngine disable/enable crash kamailio

[Ján Füri]

Hi,
I have the same experience with enabling end disabling rtpengines using 
commands like kamctl fifo nh_enable_rtpp udp:xyz.
I tested in on kamailio 4.4.3

Currently I have my rtpengines' IPs in MySQL table. Here I can disable 
or enable them. After changing parameters in rtpengine's table, I just 
need to reload it using kamctl fifo nh_reload_rtpp

so I use only :
kamctl fifo nh_show_rtpp all - for showing active rtpengines
kamctl fifo nh_reload_rtpp - for reloading my configuration

this works reliably

BR,
Jan
