PJSUA/PJSUA2: Immediately hangup on unreachable client

Hello,

I'm using mostly PJSUA2. I have an userless account set up and want to do
direct calls. The call is started via pj::Call::makeCall() and hangup via
pj::Call::hangupCall(). This is working for clients that are reachable and
sending provisional responses.

However it is not working as I intended when calling clients that are not
reachable (SIP-Uri is valid though). The call is disconnected when using
hangupCall but the session still exists. Repeating this process too fast
will result in an "PJ_ETOOMANY" error. I want those sessions to end
immediately since sip cancel won't reach the client anyway. The session
timeout seems to have a minimal value of 90 seconds.

I tried pjsip_inv_terminate, pjsip_inv_end_session and pjsip_dlg_terminate
to no avail.

Is there a way to immediately hangup on an unreachable client and how can
it be done?

Regards
Jochen Jung

I think initially it will try to resolve DNS if it's URI. If no DNS
reply, it will wait till timeout. API: pj_gethostip

You could check if this is one of the reason for delay you are
observing.

Hello Sai Mukund Sagar Deshpande,

i don't think that is my problem here. The SIP invite is sent to the
callee. At this point no resolving should take place anymore.
