Asterisk.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I do a “tcpdump” trace of the network
traffic to/from OpenSER, it is clear that a large percentage of the
INVITE requests sent to OpenSER were not handled. Asterisk needed to resend the
INVITE requests several times before OpenSER would handle them, and in about
20% of the cases Asterisk terminated the INVITES because it reached the timeout
of 30 seconds without any response.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If I go directly from asterisk to the carrier, this test
works without any issues. I’m not sure what the limitations are of
OpenSER, but this seems like something it should be able to handle.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any help or information on how to configure OpenSER so it
will work would be appreciated.<o:p></o:p></p>
