Hello,

I have trouble with REFER method that has to-tag and Route header , more than 
one.

When it pass loose_route() method ,  loose_route function remove all route 
headar  then  sets RURI with top most Route.

Is there a function that removing own route header and sets destination uri 
($du)  with top most uri.


Best Regards.

2.6<https://tools.ietf.org/html/rfc3515#section-2.6> Behavior of SIP Proxies

SIP proxies do not require modification to support the REFER method.
   Specifically, as required by [1<https://tools.ietf.org/html/rfc3515#ref-1>], 
a proxy should process a REFER
   request the same way it processes an OPTIONS request.


For example,


---------->[email protected]>>[email protected]>
1
--
REFER : sip:[email protected] ...
Route:<sip:[email protected];lr>,<sip:[email protected];lr>,<sip:[email protected]>
To: <>;tag=asdads
From:<>;tag=asd123

REFER : sip:[email protected] ...
<sip:[email protected]>,<sip:[email protected]>
To: <>;tag=asdads
From:<>;tag=asd123
