[OpenSIPS-Users] BYE generated locally going to private IP, not public IP

[Daniel Zanutti]

That makes a lot of sense.

Do you think is there anything I could do on my side to solve this? Maybe
manually fix the RR?

This client has some kind of link balancing, so public IP may change at any
time. This must be the reason he hasn't set it.

Thanks in advance!
