Thanks for your response.<div>What I found is:</div><div>1. If call is from phone registered to IP (external or internal) - then I do not need any of my modifications - ACK goes through loose_route, or t_check_trans() is OK and ACK is also OK.</div>
<div>2. If call is from phone registered to name (<a href="http://sip.mycompany.com">sip.mycompany.com</a>) - then t_check_trans is not OK, and I have problems.</div><div>I understand - it is dirty patch. May be best is if I could somehow replace from domain name with IP.</div>

Hi Mihaylov,<br>
<br>
If your Asterisk servers add a Record-Route header to the initial
Invite, for in-dialog requests ( ACK, BYE) you should use <b>loose_route()
</b>function to do the routing. This will make sure the requests go
the same path as the initial Invite. It is not a good practice to
manually route these requests. <br>
<br>

<div>Kamailio runs on same server as rtpproxy.</div>
<div>Everything is fine if clients connect to Kamailio with its IP

<div>I forward BYE and ACK in case when src_ip==$td to Asterisk

<div>If one of clients use IP - then calls initiated from it are
OK (BYE/ACK - are going correctly - to Asterisk and to other
