Hi,

> nta.c:3012 agent_recv_request() nta: REGISTER (116849) going to existing REGISTER transaction

These means that sofia is considering these requests as retransmissions (transaction found in sofia's internal htable). In this case, you should also see a retransmission log like "nta: re-received %s request, retransmitting %u reply".

The nua_application_event is calling a mod_sofia callback for incoming register request. So it looks like mod_sofia does not answer for some reason.
Can you check if you get the following esl custom events: "sofia::register_attempt", "sofia::pre_register" and "sofia::register" for the failed register? It will help to tell at which point the processing stops.

Also, is your core-db in-memory? If not, you may try to move it in ram.

Best Regards,
Vallimamod
