Hi Kamailio community,
I need your urgent help regarding a situation where the Kamailio TCP packet delayed in relaying SIP packets. They delay between the time Kamailio logs the relay to the time it left the system was ~20 seconds difference, which is huge in SIP world.
Any ideas, thoughts or suggestions on how I can narrow down to the problem? We have about 30 cases of this today
Thanks in advance.
Hello,
Could it be that your send queue or other parameters regulating outgoing flows are too low?
Stuff like this:

Thanks Alex for your response. I honestly forgot about these parameters and will play with them a bit.
Is there anyway to log how much is written or stored in the buffer?

Hello,
you can see tcp write queued bytes with:
kamctl rpc core.tcp_info
If you have an older version, do kamcmd core.tcp_info
It may be also the OS queues that are busy, if the other side is not not reading fast, look at netstat output for Send-Queue in:
netstat -altp
Cheers, Daniel

Another aspect -- are the connections to be used for transmission already open? If it is a new connection, it can be also the fact that the other side is not accepting the new one very fast.
