Summary:                    With delayreject=yes calls sometimes fail
Description: 
This is repeatable about 1 in https://issues.asterisk.org/view.php?id=11#c10
calls

Every call succeeds when commenting out delayreject=yes in iax.conf.
 
Or with delayreject=yes set in iax.conf but also commenting out the
following code in the 3 places iax2.c fixes it.<pre>
/* For security, always ack immediately */
                                if (delayreject)
                                       
send_command_immediate(iaxs[fr->callno], AST_FRAME_IAX, IAX_COMMAND_ACK,
fr->ts, NULL, 0,fr->iseqno);</pre>

Obvoiusly cannot stay this way, but the Security fix that applied these
changes looks like it broke IAX.
