if it is only for nat purposes, then you can safely send back a 200 OK using sl_send_reply() -- this will stop any retransmission of the request by the client.
It is very common to use OPTIONS for NAT keepalive, REGISTERs usually triggers authentication and user location update which will add some overhead.

Hello list, I have a question regarding to the NAT keep alive message sent by a Lynksys PAP2 device. I configured the NAT keep Alive message as NOTIFY. When this messsage arrives to SER the next configuration line handle it.
if (method=="NOTIFY") { break; };
i'm not sure if this behavior is ok. Does SER must answer to the NOTIFY (keep alive messages).?? if the answer is yes, which message is the answer to a NOTIFY? is better to do the NAT keep alive message with a REGISTER? I hope that someone could help me
