[OpenSIPS-Users] Accessing the response in a failure_route

[Răzvan Crainea]

Hi, Yuval!

Those values are null most likely because the 408 Timeout message is not 
received by OpenSIPS, but locally generated. Therefore, there's no 
actual reply to get the status/reason from.
Therefore it is safe for you to presume that if $rs/$rr is null, there 
is no response coming from UAS, so you might presume it's a 408 Timeout. 
Hope this helps.

Best regards,
