[Freeswitch-users] Baremetal, hyperthreading?

[David Villasmil]

Hello Martin,

I'll save you some money :)
It's not kamailio replying with "500 Overlapping Requests", it's freeSWITCH.
It seems to me they're sending the reINVITE WAY too quickly:

ACK to 200: Jun  3, 2020 00:35:56.421500000 WEST
(re)INVITE: Jun  3, 2020 00:35:56.430197000 WEST

(10.40.4.21 is UMG's side)

As you can see, they're sending the reINVITE about a millisecond after the
ACK. I'm not sure what FS says about this, I would have to look at FS' logs.
If UMG could hold off that reINVITE for a second I think it would
probably solve the problem.


Regards,
