Carsten you're the man!

it was a simple case of add_contact_alias(); vs fix_nated_contact();

thanks for the insights guys

Hi,

i see. However in the request from Twinkle, there is something else wrong:
For subsequent requests, the User-Agents should send it to the URI in
the Contact-Header.

It is done correctly for the ACK
Contact in 200 OK: Contact: <sip:kelvin@1X5.6X.1X6.2X3:62280>.
URI in ACK: ACK sip:kelvin@1X5.6X.1X6.2X3:62280 SIP/2.0

But it is done wrong for the BYE:
Contact from INVITE: Contact: <sip:+1178@192.168.47.68:5060>.
URI in BYE: BYE sip:+1178@6X.2X1.4.1X5:5060 SIP/2.0.

There's either a problem with your carrier or with your Kamailio
config. I'd assume it's somewhere in your config.

Kind regards,
Carsten
