[OpenSIPS-Users] Problem Opensips send two BYE

[Razvan Crainea]

Hi Mickael,

What version of OpenSIPS are you using? You can find a useful function 
on trunk: test_and_set_dlg_flag [1]
This function is executed atomically, so you can set a flag for the 
first BYE. When the second BYE comes, if the flag is set you can ignore it.

Regards,
