[OpenSIPS-Users] Disable an rtpengine with trafic issue

[Alain Bieuzent]

Hi,

 

I’m using opensips V3.0.3 with a pool of two rtpengine.

For maintenance reason, i need sometimes to stop an rtpengine server.

 

When I run the command to disable one of my rtpengine “opensips-cli -x mi rtpengine_enable udp: 10.207.201.25:2223 0”, if there is current traffic on it, the new delete commands sent by opensips are sent to the other rtpengine (10.207.201.24) ex :

In that case there ghost call on stopped rtpengine, because it never received the delete message.                                                           

Is there a way to run a graceful disable (continue to send delete or new offer for current traffic, but not accepting new call)  ?

 

thanks
