I have two CPL scripts, redirect work fine, but forwarding work as redirect!
My ser from CVS. ua is SJphone-252.
this is redirect.xml for sip:100004@192.168.2.77, when i invited 100004, redirect to
100003
------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE cpl PUBLIC '-//IETF//DTD RFCxxxx CPL 1.0//EN'
'cpl.dtd'>
<cpl>
<incoming>
<location url="sip:100004@192.168.2.77">
<redirect/>
</location>
</incoming>
</cpl>
---------------------------------------------------
this is forwarding.xml for sip:100002@192.168.2.77. I have use tcpdump on sip proxy, not
find invite request send to 100002. as redirect, sip proxy after receive invite request,
as soon as send to 100003.
