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.
