Contact header contains private address not external address

[tinpotnick]

When creating an outbound dialog using createUAC( "sip:[email protected]:41826;transport=tcp", someheadersbutdefinitlynocontactheader )

The outbound INVITE contains the contact string, which uses the private address rather than the external address. This is causing the phone to send the BYE to the wrong location.

i.e. Contact: <sip:172.18.0.7:9997;transport=tcp> I expect it to be Contact: <sip:13.42.100.65:9997;transport=tcp>

Drachtio is started with

drachtio --stdout --loglevel debug --sofia-loglevel 9 --contact sip:172.18.0.7:9997;transport=udp,tcp --external-ip 13.42.100.65 --contact sips:172.18.0.7:443;transport=wss --external-ip 13.42.100.65 --contact sips:172.18.0.7:9998;transport=tls --external-ip 13.42.100.65

If you want the contact to masquerade as the external ip, then I believe you need to do --contact sip:13.42.100.65:9997;transport=udp,tcp.

[spointer]

I think @tinpotnick sets a proper argument(--external-ip to 13.42.100.65).
If drachtio is set external-ip, i think drachtio is intended to replace the host part of well-known headers to that external-ip.

I found drachtio does not replace the host part of a contact header to the external ip inside the doRespondToSipRequest function.

// external ip is not set when calling makeTags function.
tags = makeTags( headers, transportDesc ) ;

My issue is similar to @tinpotnick and here is the log i found.
