[Serusers] CPL

[Toni Barata]

Hi Bogdan,

Thanks for the recomendation ;-)
But I still have some troubles with the script for "proxy if no answer".
If I upload the following script on the user, e.g. "client1", the "proxy if
no answer" works for the new url (in the first location tag):

<cpl>
  <incoming>
    <location url="sip:client2 at 10.112.128.5">
      <proxy>
        <noanswer>
          <location url="sip:client3 at 10.112.128.5">
            <proxy />
          </location>
        </noanswer>
      </proxy>
    </location>
  </incoming>
</cpl>  

But if the "new" url is the same of the client who have uploaded the script
(client1), like in the following script, the ser respond with a "too many
hops error":

<cpl>
  <incoming>
    <location url="sip:client1 at 10.112.128.5">
      <proxy>
        <noanswer>
          <location url="sip:client2 at 10.112.128.5">
            <proxy />
          </location>
        </noanswer>
      </proxy>
    </location>
  </incoming>
</cpl>

So my question is, how can i implement the script to activate the proxy no
answer to the user who will upload the script?

Many Thanks,
Toni

Hi Toni,

the problem is that your script is wrong. Please read carefully the 
cpl-draft from ietf 
http://www.ietf.org/internet-drafts/draft-ietf-iptel-cpl-08.txt (there 
are also several examples there).
Some hints: when you do proxy, your location set is empty - there is no 
location or lookup tag before and for incoming processing the location 
set is init as empty. That's the reason for this message:
(17752) DEBUG:run_proxy: location set found empty -> going on 
failure/default branch
and as your proxy tag has no failure/default branch, the interpreter 
will return to SER script (default behavior).

About timeout, yes indeed, it is not supported for the moment. This 
parameter is totally ignored.

Regards,
Bogdan
