[OpenSIPS-Users] Problem Opensips send two BYE

[Razvan Crainea]

Hi Mickael,

The function was also added in OpenSIPS 1.6.4 in svn revision 8195.
If you script is dialog aware, then using this function will work.
You can catch the locally generated BYE in a local_route. There you can 
use this function to test if the BYE has already been relayed.

Regards,

Razvan Crainea
