[SR-Users] Call termination via dialog RPC dlg.end_dlg for the SIP-UA behind NAT

Hello!

When calling RPC command dlg.end_dlg, BYE for leg behind NAT sends
according to the Contact header not to the real ip:port.
RPC ul.dump shows correct address in Received: sip:2.2.2.2:7488, but looks
dialog does not know real address.

How can I force sending to the real address?
