<br>
We build FS-based PBX and faced issue with identifying outbound<br>
channels created by FS in case of receiving 302. We don't use internal<br>
redirect as it leads to redirecting source channel.<br>
Instead, we use enterprise originate and make FS send all channels to<br>
SBC which sends them back to FS in case of redirect.<br>
<br>
Problem is that after FS sends call redirected by 302 to SBC, we can't<br>
distinguish between usual originated calls from FS and redirect<br>
attempts as there is no significant difference in SIP fields. It would<br>
be great if we can for example set some header to identify redirected<br>
call from FS on SBC.<br>
<br>
Maybe you guys have some thoughts about how this can be done?<br>
<br>
