[SR-Users] SIP re-invite Packets

[Ali Taher]

Hi Alex,

So loose_route() is only responsible of In-dialog requests ?

Can you please send me a simplified config that suit my case ?

Noting that I'm using Kamailio only as proxy between my customer and my supplier.

Much appreciated.

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
