The problem regards the hangup cause that Freeswitch is sending to their softswitch, to allow a their automatic rerouting based on some Hangup Cause.<br>I got a request to send different Hangup Cause, so the Customer switch can automatically reroute call to another carrier. Here is the explaination<br><font class="Apple-style-span" color="#0064c3"><br><br></font><b>The scenario is:</b><br>All the endpoints are using a Public IP and no NAT is involved in these steps.<br><font class="Apple-style-span" color="#0064c3"><br></font>CUSTOMER ------------------> MY_FREESWITCH -----------------> REMOTE_CARRIER<br><font class="Apple-style-span" color="#0064c3"><br><br></font><b>What happen now:</b><br>The customer can send calls. On My freeswitch I will route calls based on Dialled Prefix to a Remote Carrier. <br>In my Lua script there is a conditional IF to check for remote disconnect cause, however it seems that the Release Cause is already sent (CALL_REJECTED) when I'm checking with my IF and so, even if the cause has been already sent it's sent again but what "win" is the first hangup sent.<br><font class="Apple-style-span" color="#0064c3"><br><br></font><b>What should be:</b><br>If the remote carrier will send me a CALL_REJECTED (isdn 21) I need to send to the remote customer another Hangup Cause for example: NORMAL_CIRCUIT_CONGESTION (isdn 34).<br>How to implement that?<br>I can create this remapping using a Diaplan XML configuration, but as I'm using a Lua script to manage the call, I found that is a Lua task to deal with the Hangup Cause, the dialplan rules are ignored.<br>The "telephony" part of the Lua script is working, what I'm trying to change is the release cause to make my customer happy as with a different release cause he can route traffic correctly and I will not loose my reputation :)<br><font class="Apple-style-span" color="#0064c3"><br><br></font><b>Below there is my Lua script (just the routing part)</b><br><font class="Apple-style-span" color="#0064c3"><br></font>Thank you so much!<br>Cheers<br>Max<br><font class="Apple-style-span" color="#0064c3"><br><br><br><br><br></font><blockquote type="cite"><div style="word-wrap: break-word;
