[SR-Users] Kamailio with 2 Public and Private IPs- SIP Call flow issues

[Federico Cabiddu]

Hi,
your INVITE contains a single Record-Route, with Kamailio's Public IP
address. Freewitch in the following in0dialog messages, as the BYE is, will
have nowhere else to send them than the public IP.
If you want FS to send in-dialog messages to the private IP you have to
have two Record-Route headers:

Best regards,

Federico
