<p class=MsoNormal>Dear,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>What would be the best way to change SIP response message
from 5xx to 4xx. The problem is we have client with a broken b2bua which sends
SIP 500 Expired after the user does not answer the phone, so I would like to
change it to SIP 480 Temporarily unavailable message before sending it back.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>if (search("^Expired*")) {<o:p></o:p></p>
<p class=MsoNormal style='text-indent:35.4pt'>sl_send_reply("480",
"Temporarily Unavailable");<o:p></o:p></p>
<p class=MsoNormal style='text-indent:35.4pt'>break;<o:p></o:p></p>
<p class=MsoNormal>};<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I thought about something like that but that would match
also the initial invite that has Expired valule in it, so I would need to match
only SIP 500 message with string Expired in it.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thank you<o:p></o:p></p>
