[SR-Users] SIP re-invite Packets

[Alex Balashov]

Hi,

In-dialog requests must be handled using loose_route(). You can find the
proper boilerplate in the stock configuration file:

https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg#L587

To note, your config is not sufficient to handle all aspects of a call
between endpoints in an adequate way. You will want to consider the main
request_route in the main config file and adapt its most essential
aspects accordingly:

https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg#L455
