Hi All.
When someone dials 411 I want to rewrite the request before sending it out to the PSTN
gateway.
For example if my SIP phone user name is 4071234567 and I dial 411 I want to send the
request out
to the PSTN gateway as 4075551212 for directory assistance so that the subscriber's
__local__
directory assistance is dialed.
How can I do this using -dev23?
Regards,
Paul

A somewhat brut force method I use is to add a rule to the digitmap or
digit pattern in the phone itself. For example, an unprovisioned phone that
loads the generic config file, of any supported manufacturer, off our tftp
server ends up with a digitmap file that sends all calls to a specific
helpdesk
number. It doesn't matter what digits this type of user presses all calls
get sent to the help desk so they can be provisioned.
Once provisioned loading the generic config file loads the same digitmap
file but now the phone also gets a phone specific config file. This file
specifies
the "provisioned user" digitmap file that overwrites the generic one. In the
"provisioned user" digitmap file we rewrite 511 and 911 to be our local
Safety Office phone number.
This approach prevents an unprovisioned phone from mangling the service
yet attempts to help the call get provisioned. At the same time a
provisioned
user doesn't need to think about where emergency calls go. We tell them in
the phone config (we also check the called number in the proxy for extra
measure).

Hi All.
Just in case anyone needs to do this same thing here is how I got it to work:
Regards,
Paul
route {
# usual stuff
if (method=="INVITE" && uri=~"^sip:411@.*") {
# flag 30 is set by a call to is_user_in() to check
# for membership in a group I called "411"
if (isflagset(30)) {
avp_write("$from", "i:34");
avp_pushto("$ruri", "i:34");
# this assumes **ALL** subscribers use a 10-digit
# telephone number as their username
strip_tail(7);
subst_uri('/^sip:([0-9]+)@(.*)$/sip:\15551212@\2/i');
route(3); # send to PSTN gateway
break;
};
# reply 503 since the user doesn't have acl 411 granted
sl_send_reply("503", "Service Unavailable");
break;
};
# lookup aliases, lookup location, etc, etc
}
