> Hello all,
> Recently, we upgrade to version Asterisk 13.1.0 with chan_sip stack. With 20 calls there was no problem. But now this server handles 150 concurrent calls and I get the following error : Retransmission timeout reached on transmission

> The problem occurs about 1 time a day. When this message appears the server begins to reject calls. They are all gradually declined. We are forced to restart the daemon to make the service works again.
> Have you ever encountered the same issue? We are unable to reproduce the problem. I specified that we don't use SIP SBC or NAT in this scenario.
