Hi Manuel,

Hello,

What is the correct way to send ACK messages? During an invite
transaction, for example, the ACK is sent after the OK, isn't the
transaction terminated by that time?
 
This is correct! 

You can take a look at src/eXcall_api.c, line 362:

http://git.savannah.gnu.org/cgit/exosip.git/tree/src/eXcall_api.c#n362

The method "eXosip_call_send_ack" is building an ACK and is calling
directly the callback to send SIP message, ie, not through a finite state machine.

And parameter "transaction" is left to NULL. Your "send" method must be prepared
to do this.

Regards
Aymeric


Thanks!
