[SR-Users] [tm-local-request] usage

Greetings,

I did some testing and onsend route is not executed on local generated
requests.

I asked if they work the same way because for relayed requests, the on send
is the last route before sending the packet.

I'm asking this because I'm trying to debug an issue with my probings via
dispatcher, where some OPTIONS requests are not being sent to its
destination. I got a log on local-request and all OPTIONS are logging there
correctly. However, if i do a pcap capture on the kamailio machine, not all
options are there.  That being said, i want to make sure that the problem
is not in my Kamailio configuration and it is sending the correct number of
packets.

Best regards
