<div>Hi Daniel,</div> <div>Thanks for your response. My configuration was OK. My problem got solved after I removed the function consume_credentials() from route(3). After the forwarding, the openser used to ask for proxy authentication again. This was the problem.</div> <div>I was also trying to implement forwarding if the user is not registered. My config seemed to be ok, but when I tried testing this feature, openser gives me a message saying:</div> <div>513-message too big. Can someone please explain me what this means and how to rectify this problem.</div> <div> </div> <div>Thanks in advance</div> <div> </div> <div>w/regards,</div> <div>jayesh..<BR><BR><B><I>Daniel-Constantin Mierla <daniel@voice-system.ro></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Hello,<BR><BR>have a look at<BR>http://www.voice-system.ro/docs/avpops/ar01s08.html#ex_serial_forking<BR><BR>the
