[SR-Users] Dialog module problem.

[Voip support]

I would like to mention one more thing. Documentation says:

The dialog is automatically destroyed when a “BYE” is received. In case of
no “BYE”, the dialog lifetime is controlled via the default timeout (see “
default_timeout” - Section 6.6, “default_timeout (integer)”
<https://kamailio.org/docs/modules/5.1.x/modules/dialog.html#dialog.p.default_timeout>)
and custom timeout (see “timeout_avp” - Section 6.5, “timeout_avp (string)”
<https://kamailio.org/docs/modules/5.1.x/modules/dialog.html#dialog.p.timeout_avp>).
The dialog timeout is reset each time a sequential request is processed.

But in my case i can see on wireshark BYE received from caller and callee
side but when running kamctl dialog show command the dialog is still on the
list.

Best regards,
Tom
