Thanks for your email.

Yes dlg_manage(); has to now be called on INVITE and BYE/CANCEL messages. Where would i have to call loose_route()? Only on INVITE?

On *all* in-dialog requests, i.e., all requests which contain a To tag. This may include Re-INVITEs too (but not initial INVITEs).

My configuration did not change between 3.1.2 and 3.1.5.

Call flow example:

Cisco PGW ===> Kamailio 3.1.5 ===> VOIP PROVIDER or ASTERISK PABX

The below is my configuration.

Let's take a look at it:

#!KAMAILIO #

[...]

     if(is_method("BYE|CANCEL"))

  {

     dlg_manage();



    # per request initial checks
    route(REQINIT);

    # NAT detection
    route(NAT);

    # handle requests within SIP dialogs
    route(WITHINDLG);

[...]

# Handle requests within SIP dialogs route[WITHINDLG] { if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) {

[...]

So route[WITHINDLG] contains the logic to track in-dialog requests. However, you seem to call that route only from BYE and CANCEL requests, missing out ACKs, which is likely the reason why things go wrong. So make sure you run all in-dialog requests through that route, and you should be fine (hopefully).

Cheers,
