<div>Thanks for your clear answer.</div><div>But I find thinks a bit different. we do collect the FS events during ESL mod event_socket, and find that the Unique-ID changes by channel.</div><div>What I try to do is, we have a FS server, each call comes in via the server, there were made some logic like answer, greeting etc. and also saving the call in DB. from there it goes to a client extension to get the call, speak, hang up etc. when it comes to the client I need to know which call it is in the server and in the DB. </div><div>The only variable the client gets from the server is sip_call_id, and now after your explanation I understand why, since this is outbound.</div><div>My problem is that this variable also changes when bridging, it begins with one value then when bridging it changes to another value. the client gets the second value after bridging, and I cannot find this new value in early events like 'CHANNEL_CREATE' or 'CHANNEL_ORIGINATE', it only appears in later events like 'CHANNEL_PROGRESS' when the client already ringing, and this is a bit late.</div><div>In short, I need a unique variable to can recognize the incoming call to the client with the incoming call to the server.</div><div><br></div><div data-signatureblock="true"><div>Israel Fink - Developer<br>Machshevet team</div><div><br></div></div><div style="padding-top: 5px; border-top-color: rgb(229, 229, 229); border-top-width: 1px; border-top-style: solid;"><div><font face=" 'Calibri', 'Arial', 'Segoe UI', 'Meiryo', 'Microsoft YaHei UI', 'Microsoft JhengHei UI', 'Malgun Gothic'" style='line-height: 15pt; letter-spacing: 0.02em; font-family: "Calibri", "Arial", "Segoe UI", "Meiryo", "Microsoft YaHei UI", "Microsoft JhengHei UI", "Malgun Gothic"; font-size: 12pt;'><b>From:</b> <a href="mailto:brian@freeswitch.org" target="_parent">Brian West</a><br><b>Sent:</b> Friday, November 7, 2014 12:23 AM<br><b>To:</b> <a href="mailto:freeswitch-users@lists.freeswitch.org" target="_parent">freeswitch-users@lists.freeswitch.org</a></font></div></div><div><br></div><div dir=""><div dir="ltr">1.
