Dial destination is truncated if longer than 80 chars

I have a problem when I try to make a call to a destination string longer than 80 characters; i’m using Asterisk 1.2, Fedora core 3 (but the problem was the same even with *@home 1.0): I show the details in this example:

This first line in extensions.conf works well: when dialing 208 the mediaserver gets the jsp voicexml page from the web server and the customers starts the dialog:
exten => 208,1,Dial(SIP/portal.vxml.http%3A%2F%2F213.171.104.143%2FA%2Fservlet%2Fp.HDesk@

The asterisk console gives these lines:
– Executing Dial(“SIP/205-49e2”, “SIP/portal.vxml.http%3A%2F%2F213.171.104.143%2FA%2Fservlet%2Fp.HDesk@”) in new stack
– Called portal.vxml.http%3A%2F%2F213.171.104.143%2FA%2Fservlet%2Fp.HDesk@
– SIP/ is ringing
– SIP/ answered SIP/205-49e2

This second line, almost identical to the preceeding, but with longer folder, package and servlet names, doesn’t work:
exten => 210,1,Dial(SIP/portal.vxml.http%3A%2F%2F213.171.104.143%2FMsVxml%2Fservlet%2Fmspackage.MsHelpdeskServlet@

and the console gives these messages:
– Executing Dial(“SIP/205-59a9”, “SIP/portal.vxml.http%3A%2F%2F213.171.104.143%2FMsVxml%2Fservlet%2Fmspackage.MsHelpdeskServlet@”) in new stack
Nov 9 15:45:34 WARNING[4004]: chan_sip.c:1947 create_addr: No such host: portal.vxml.http%3A%2F%2F213.171.104.143%2FMsVxml%2Fservlet%2Fmspackage.MsHelpd
Nov 9 15:45:34 NOTICE[4004]: app_dial.c:975 dial_exec_full: Unable to create channel of type ‘SIP’ (cause 3 - No route to destination)

where you can see that the url string is truncated at 80th character.
This problem becomes serious when I have to pass some parameters, as in the following case:

exten => 210,1,Dial(SIP/portal.vxml.http%3A%2F%2F213.171.104.143%2FMsVxml%2Fservlet%2Fmspackage.MsHelpdeskServlet%3Fcaller%3D${CALLERIDNUM}%26callee%3D${DNID}@

Here I cannot reduce the total length in 80 chars, and so I have to solve the problem.

Has someone else encountered the same problem? Do you know any solution, please?

Please do not double post.


Sorry for the double post, it wasn’t so clear to me what forum could be the right one, for my question.
I hope, however, that almost one of my two msgs will be read (and possibly answered, asap).
