Hi,
I'm checking for a Re-Invite (Hold)

The Invite from the UA is like this:

SIP MESSAGE 1        10.46.11.132:5060() -> xxx.xxx.xxx.xxx:5060()
UDP Frame 1        28/Sep/06 10:45:38.0422
TimeFromPreviousSipFrame=0.0000 TimeFromStart=0.0000
INVITE sip:67512388 at 10.46.11.101:5060;user=phone SIP/2.0
Via: SIP/2.0/UDP 10.46.11.132;branch=z9hG4bKeb3ee7f3572b7f4b
Route:<sip:xxx.xxx.xxx.xxx;lr=on;ftag=9f2aeb7dd809d46d;nat=yes;did=3c4.85d80b74>
Route:<sip:yyy.yyy.yyy.yyy;lr=on;ftag=9f2aeb7dd809d46d;nat=yes>

I do a check_route_param("nat=yes")

Should not this work?

from the doc it says check_route_param:
The function checks if the URI parameters of the local Route header
(coresponding to the local server)

I'm also calling the function after loose_route()
