Hello,
It's happens around 40 calls and above ?
The **machine** accepts number of invites(we can see by tcpdump ) , but
asterisk sees part of them (we can see by CLI log) , and when it does ,
asterisk accepting an invite it reply the initator. (as it should ) ? but
the rest of invites are just ignored.
it's seems like an O/S issue, because on asterisk level I can all going
correctly via logs (invite is accepted=> packet is generated=> and 180
is
sent immediately to the initiator ?)
which tools can help me check kernel issues ?
Also,
tried to increase udp buffer (sysctl -w net.core.rmem_max=8388608) , but
seems the problem still persists.
Also , here a screenshot of a typical dump from network interface, you can
clearly see what's going on.

did you isolated the issue? , checked firewall , interface errors , routing
, sniffed the interface?.
also , why using h323 and not IAX2 ?

I am having a similar issue. Asterisk does not show ringback tone and I
investigated this due to it not reading sip invite 180. (or supposedly not
receiving it).. My solution is that now I am using h323
(ver 1.4.19)
