[OpenSIPS-Users] Route Header removal

[Răzvan Crainea]

Hi, Louis!

Almost all changes (perhaps the only exception is the R-URI and parts of 
the Contact header) performed on the SIP message will only be visible in 
the outgoing message, but *NOT* reflected in the script. This means that 
whatever change you perform to the message will not be visible by the 
functions used - this is the intended behavior.
If you don't want to route according the the Record-Route algorithm, 
you'll have to catch the request in the local_route and force sending it 
to whatever other destination you want.

Best regards,
