Big delay in audio after answer queue call

(Danial) #1

I 'm using Asterisk 13.20 and Freepbx 10.13 on a virtual server(8 cores CPU , 16 GB RAM ) we have multi queue and call recording
here is my problem: When queue increase in call volume (about 20 waiting calls ) calls ditributed normally but after agents answerd calls , there will be long delays in hearing the caller’s voice.

In log files there is a related warning message:
[2018-12-05 15:14:30] WARNING[31027][C-0000c3f0] channel.c: Exceptionally long voice queue length queuing to Local/1057@from-queue-0000fa42;1

more info :
-we have two servers with same hardware and software config and both of them have this issue .
-these servers connected to remote mysql (LAN server) by ODBC to store CDRs.
-All clients and servers are on LAN network without firewall or NAT devices , we don’t use DNS for client registering or trunks.
-Asterisk still working with no crash or core dump files.

in same time “queue show” command responses with delay:
