Bogdan its only happening when the clients SIP ALG fixes the contact, when the contact is broken I'm already using fix_nated_contact, do you think I should use fix_nated_contact even when the contact was already fixed by the SIP ALG?
The clients router does not support disabling SIP ALG, I can try using a non standard port, I've sen some routers ALG ignoring the packets when sent to alternative port. I feel like its a bug in OpenSIPS, because the reinvite is routed to the proper port, the issue starts with the ACK for the reinvite, I will email the trace directly to you.
