[OpenSIPS-Users] Maximum number of ReINVITEs option?

[Jehanzaib Younis]

Hi Ray,

I did not see any built-in way to restrict the number of re-invites. The
problem with this buggy client is, if your SBC does not respond the
client's reinvite. It might send BYE ;) so even if you restrict the
reinvites that might not work well.


Regards,
Jehan
