A duplicated INVITE ...

Good morning all,

I am sorry to bother again, but have a strange problem with JAIN
(I tried the last version because I hoped that it had been fixed, but
it is still present).

My application is a SIP client (UAC) and it seems that, sometimes, even
though rarely (sometimes every 1000 or more calls) the client, after the
ACK, it sends another INVITE with the same CSeq of the first one (which
started the SIP transaction).

does anyone encountered this problem?

I did not set particular properties on the stack, just the one I found in 
the
example, i.e.

sipFactory.setPathName("gov.nist");
properties.setProperty("javax.sip.IP_ADDRESS", originatorAddress);
properties.setProperty("javax.sip.OUTBOUND_PROXY", proxyAddress + ":" + 
proxyPort  + "/" + protocol);
properties.setProperty("javax.sip.ROUTER_PATH", 
"gov.nist.javax.sip.stack.DefaultRouter");
properties.setProperty("javax.sip.STACK_NAME",  "MyStack");
properties.setProperty("javax.sip.RETRANSMISSION_FILTER", "true");
properties.setProperty("gov.nist.javax.sip.READ_TIMEOUT", "1000");
properties.setProperty("gov.nist.javax.sip.CACHE_CLIENT_CONNECTIONS", 
"false");

furthermore the problem do not occurs on fast machines, but it seems related
to slow machines / high CPU load ....

thank you all in advance !
