I have searched for examples and have had no luck.   Thank you   *From:*Daniel-Constantin Mierla [mailto:miconda@gmail.com] *Sent:* Friday, February 9, 2018 7:48 AM *To:* Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org>>; Wilkins, Steve &lt;swwilkins(a)mitre.org <mailto:swwilkins@mitre.org>> *Subject:* Re: [SR-Users] t_relay()?   Hello, before t_relay() you can't see what is going to the network, because some headers are added when knowing target address and local socket (e.g, Via, Record-Route). You can use onsend_route for seeing the request just before writing to the network. https://www.kamailio.org/wiki/cookbooks/devel/core#onsend_route $snd(buf) will give outgoing buffer -- for more see $sndfrom(...) and $sndto(...) vars.
