How to always use the public IP on SIP even for LOCALSUBNETS?

[Ricardo Duarte]

Hi there,

I need to make 3CX only use the Public IP on SIP/SDP messages.
But it always put it's own private IP on them when the phone is a member of LOCALSUBNETS.
I already tried to set SINGLE_SIP_IP = 1 , and SIPINTERFACEIP = <my public ip> , but still 3CX puts the local IP on the messages.
What can I be missing here?

Thanks
