Hello,
Hi Roger
I just checked "void ict_snd_invite (osip_transaction_t * ict, osip_event_t * evt)"
If you confirm that you returned 0 from your "cb_send_message" callback, then
the issue might be related to issue with "Via" header. The cb_send_message wil
be called if the Via is not correct for example. There are other use-case where it
may be called.
The easiest would be to put a breakpoint in ict_handle_transport_error and see
why it's called! Give the backtrace & full logs.

I wonder, why the callback function for transport error is called
in my programm.
My programm is accepting an INVITE from remote, is sending back
100 Trying immedeately, and then sending a new INVITE to another
IP address.
osip is calling my call back function cb_send_message(), which
sends the INVITE and returns with 0.
And then immedeately my cb_transp_error() is called with that
INVITE message as argument (less than 1 ms later).
How can osip guess, there is a transport error that quickly?
Any ideas, what can cause it?
The invite and the log follow here.
Regards,
Roger.
