<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have the following scenario:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>UA1 ----> B2BUA1 (top hiding) ----> REGISTRAR --->
B2BUA2 (top hiding) -----> UA2<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My problem is that the 'To' header sent out in request from
(say) UA1 is modified B2BUA2. How can I prevent this from happening?<o:p></o:p></p>
<p class=MsoNormal>I am on OpenSIPS 1.11.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
