[Freeswitch-users] No dial-string available error

Hi,
Well, that's a coincidence.. I've been busy trying to figure out that
same problem the entire weekend :-)
FS needs to know where to lookup the registered user, by indeed
setting a dialstring.
The dialstring is described in the wiki page that's mentioned, but
there's something more:
It says on that page that you should set a param in your user like this:
<param name="dial-string" value="${sofia_contact(${dialed_user}@$
{dialed_domain})}"/>
You can also test it in your cli like this:
expand echo ${sofia_contact(username at domainname)}
This will reply with:
error/facility_not_subscribed
sofia_contact will search your db in sip_registrations for all
registered users. The actual arguments that can be given to the
function are:
profilename/username at domainname/arguments
If you leave out the profilename, it will put your domainname there.
The function then checks whether a *profile* exists with that name,
and then lookup the entries in the db and then returns them.
This can be fixed in two ways: either you specify the correct
profilename (where the users are registered) with the sofia_contact
function, or you alias the domainname to the profile where the user is
registered in your sip profile.
The alias can be set in your profile like this:
<aliases><alias name="domainname"/></alias>
or automatically like this:
<domains><domain name="domainname" alias="true" parse="false"/></
domains>
(where domainname can also be "all" to alias all domain names)
But this presents another problem: The domain names that are aliased
in the last way are retrieved from the database at startup of
mod_sofia, and it is done through a directory lookup with
purpose=gateways, even though the parse attribute - which is for
getting gateways - is set to false !! (took me some time to figure
that one out)
So, I rewrote the mod_xml_odbc a bit so the set-channel-variables
function does expansion on all attributes (from-name, from-value, to-
name, to-value), and wrote the following template:
<include>
<!-- purpose=gateways is not only called for getting gateways, but
also for getting a list
of domains that will be aliased to a profile if <domain ..
alias="true"/> is set -->
<template name="directory-gateways">
<document type="freeswitch/xml">
<section name="directory">
<xml-odbc-do name="set-event-header" to-name="where-clause"
to-value="`${key_name}`='${key_value}'"/>
<xml-odbc-do name="set-event-header" if-name="where-clause" if-
value="``=''" to-value="1"/>
<xml-odbc-do name="query" on-empty-result-break-to="not-found"
value="SELECT name AS domain_name FROM
dir_domains WHERE ${where-clause};">
<domain name="${domain_name}"/>
<!-- select all gateways of users within this domain_name
here, to make parse=true working -->
</xml-odbc-do>
</section>
</document>
</template>
</include>
This will simply return a list of all domains if no key_name and
key_value were specified in the lookup, or list one domain if that is
requested.
The updated mod_xml_odbc and the directory-gateways.conf.xml template
are in svn trunk contrib.
This does work for me now but still some things feel a bit strange to
me (perhaps someone can explain?):
For examplle, right now, when I have two profiles where users can
register with the same domain (for example one with a v4 and one with
a v6 address), what should I do ? I can't alias the same domain to two
profiles, so that means I have to call sofia_contact twice, once for
each profile ?
regards,
Leon
