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

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 ...

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!
