Got it - I had to change the complete asterisk-packages (I'm compiling
on base of spec file) - and not just the asterisk-core.

I can now say, that asterisk / pjsip seams to work *mostly* as expected.
Just one exception - and that's the package in question, which can't be
seen in tcpdump.

I extended the above patch by adding the info at the last output:

ast_debug(3, "PJ_TRUE 3 - ready %s\n", pjsip_rx_data_get_info(rdata));

This gives, that for *all* received packages return PJ_TRUE is reached.

But: all packages besides of the phantom resend use the same address
rdata0x7f963c0009b8 - only the phantom resent package uses
rdata0x7f9654081e18. I think, that's the problem. But I don't know what
it means and where it comes from. Do you have an idea?


Thanks,
Michael

Not without setting up the scenario and digging deep into it. Nothing
immediately springs to mind.

After enabling pjsip specific debug log in asterisk, I can see, the
following behavior:
Incoming packages from network are always signaled like this (e.g.):

sip_endpoint.c Processing incoming message: Request msg INVITE/cseq=10
(rdata0x7f5f1801a758)
<--- Received SIP request (918 bytes) from UDP:195.185.37.60:5060
...


The path of the critical not existing package is like this and can't 
be seen elsewhere (there wasn't any corresponding incoming 
message entry before):

sip_endpoint.c Distributing rdata to modules: Request msg INVITE/cseq=10
(rdata0x7f5f100e4c38)
<--- Received SIP request (918 bytes) from UDP:195.185.37.60:5060 --->
...

Normally, "Distributing rdata to modules" can be seen only if 
pjsip_rx_data_clone is called like in res_pjsip/pjsip_distributor.c

This is really odd, because if the fax is sent locally (w/o provider) 
directly between the same extension, this behavior can't be seen and 
therefore it's working fine as expected!



That's the complete critical excerpt, starting with the regular reInvite
received from provider:
