How to send BYE from callback function

[ates]

Hello,

Not an issue, just a question:

I use the following code to perform INVITE request:

nksip_uac:invite(Instance, To, [{callback, F}, {add, <<"Session-Expires">>, <<"1800;refresher=uac">>}, {body, nksip_sdp:new(<<"auto.nksip">>, Codecs)}])

Where F in callback option is

 F = fun
        ({resp, 180, Resp, _Call}) -> %% 180: Ringing
        %% Here I need send BYE request
 end,

I tried to use the following inside F function

{ok, Id} = nksip_response:meta(dialog_handle, Resp),
nksip_uac:bye(Id, []);

But got

error sending work {send_dialog,<<"1gnl6P">>,'BYE',[]}: looped_process

Should I extract the dialog_handle from _Call ? Or how to do that in correct way?

Thank you.

Looks like found how to do that - need send BYE request outside callback function, e.g. through spawn.

One more question: do nksip really need have SASL application in dependencies?

Hi Artem

I just going to tell you exactly that. You can't send any request with the same Call-ID inside the callback function (since it is the same process). You must use a spawn. I'm not sure about sasl dependency. I don't remember using it for anything... you could try to remove it a see what happens.

Tried to remove SASL from nksip.app.src - nothing is broken, so I think it would be better to remove the SASL application.

Also found one more problem with the madtrick/wsock dependency, the application which use nksip can't be started from release. Here is a pull request: https://github.com/madtrick/wsock/pull/6, but no answer for a long time.
