we are using kamailio 5.1 with siptrace module in trace_mode on. Everything works perfect except that option pings from nathelper module do not get duplicated. Is there a reason for that?

Hello Roman,

the nathelper module uses a low level core function (udp_send or send_raw) to send out the OPTION ping. This low level function does not contains the callbacks that are responsible for transferring the message to e.g. the siptrace module. This is the reason for this behavior your are seeing.

You can open a issue on our tracker about this topic, that the module authors or somebody else could take a look to this issue.

Best regards,

Henning
