[OpenSIPS-Users] Modify Invite

[Brad Bendy]

Hi,

Im bringing this back up again.

Ive had to switch our INVITE format as some upstreams parse the INVITE
differently, I just need to change the order of variables around.

Now the weird thing is, I set the $ru and then when I check to see what
$ru is set to, it's been set correct, the order and all variables are
correct, but then openSIPs sends the INVITE out it fails to modify it at
all.

I was using:
$ru='sip:' + $rU + '@' + $rd + ';npdi=yes' + ';rn=' + $avp(s:lrn);

now
$ru='sip:' + $rU + ';npdi=yes' + ';rn=+1' + $avp(s:lrn) + '@' + $rd;

Before the INVITE would look like:

INVITE sip:+11235559999 at 1.1.1.1;npdi=yes;rn=+11235559999 SIP/2.0

but now it should look like INVITE sip:+11235559999;npdi=yes;rn=
+11235559999 at 1.1.1.1 SIP/2.0

it currently looks like INVITE sip:+11235559999 at 1.1.1.1 SIP/2.0.

Any ideals why just the positions of the AVPs and the other text would
matter? I think it's weird when I use xlog() to print what $ru is set to
it shows the correct value just OpenSIPs does not modify the INVITE. Not
sure if anyone else has ran into this on the list or not.

Thanks!
