[Freeswitch-users] SIP Client couldn't receive BYE

[Jimmy Chang]

Hi Florent,

The parameter sip_sticky_contact solved my problem, too.
Since there is no docuementation about this parameter, do you know what 
does the parameter exactly do?
Is there any side effect that I turn it on?

Thanks,
Jimmy
