Hello,

I am suddenly having my log flooded by these warnings:

WARNING: Retransmission timeout reached on transmission
1372443000-1325687561-974574282 for seqno 1 (Critical Response)
WARNING: Retransmission timeout reached on transmission
283912657-2003707522-1284343849 for seqno 1 (Critical Response)
WARNING: Retransmission timeout reached on transmission
1194054411-1178477038-106915148 for seqno 1 (Critical Response)

There is also a link to the wiki in the log message:

— See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions#012Packet timed out after 32000ms with no response

but still, I was not able to find out what this means, and which connection/extension this relates to.

What does this actually mean, and how can I get rid of these warnings?

thanks,

—

  • Check to see if you are being sent INVITES from random IP’s. If the attackers don’t have their scripts set up correctly they don’t respond correctly to your responses which Asterisk does not like.
