Does anybody have any tips on solving the following
I want to differenciate between offline users and unknown users. When
you use lookup("location") there is no differenciation between the two.
Does this require uri_db ?
Using 0.8.14

I think does_uri_exist() from the uri module should do the job.
Note: if you reply with different codes on existing and non-existing users,
your community becomes an easy target for potential spamers.

Apart from the spammers I need to get a seperate cause code back to the
PSTN (if user is not diverted to voicemail) as retunring 504 gives
announcement "This is an invalid number". Also I only want to divert
valid numbers to voicemail.

Sorry did you meant 404 gives "This is an invalid number"?
Otherwise I would be interested which vendor/ITSP convert the return code "504
Server Time-Out" (according to 3261) into such an announcement, and into what
the return code 404 gets converted.

Yes typo - 404.

So I added the does_uri_exist to my offline user check and received the
following error upon startup. The problem is not obvious to me. Nils
have you
seen this error? If so any advice on how to proceed?
Aug 31 06:32:54 ser[20035]: register_udomain(): Invalid table version
(use ser_mysql.sh reinstall)
Aug 31 06:32:54 ser[20035]: domain_fixup(): Error while registering domain
Aug 31 06:32:54 ser[20035]: ERROR: fix_expr : fix_actions error
Commenting out the if-then block containing the does_uri_exist removed
this error.

It looks to me as the tables in your database, which you once created with
ser_mysql, are older then the uri module which you use. So you probably need
to "update" your database tables (like suggested with the 'ser_mysql
reinstall' command).

This is interesting. I suppose you'd have to add an extra field contact
in table 'subscriber' to get a positive result - and of course the value
in contact would re-write the uri so you should do it after
lookup("location").
Will give it a try. Br /Kev./

ser doesn't like lookup on subscribers table even with contact field
added, it must need an identical table to aliases/location.

You can only lookup domains which have an appropriate table format like
"location" table has, because usrloc tries to preload that domains on
SER startup, and this will miserably for "subscriber" because of wrong
table version, missing columns etc.

I suppose one solution is to create a table (say voicemail) of type
location/alias and put a url pointing to voicemail/announcment in the
contact field for any sub you want to divert.
something like
if (!lookup("location")) { #ok it's offline or unknown
# alternate routing like PSTN here.
if(lookup("voicemail")) {
route(1); #send it off to uri from contact field
break;
}
sl_send_reply("404", "Not Found");
}

That's what we use for call diversions, yes. Another possibility would
be to use avp_db_load(...) which is easier for provisioning because you
don't have to insert the contacts into all your SERs via FIFO/unixsock...

The problem I have with does_uri_exist() is it matches the full uri, I
may have requests from the same user using different domains in the uri
ex. calls from PSTN would have user(a)pstn.gateway.com others could also
have user(a)sip.domain.com or just plain old user(a)domain.com depending on
how they were resolved. I don't want to re-write the uri domain part
because I'm also serving multiple domains. I know I could add an alias
for all these but I was looking for a simpler alternative.

But if you use domains then a lookup(...) will fail like
does_uri_exists() because it must match the user- and domain-part too.

The server serves multiple domains but not using domains module, using
multiple alias="xxxxx". We use E.164 numbers as usernames but these can
be attached to multiple domains. br /Kev/

i accept your point regarding calls from pstn gw provided that the user
part of the r-uri is an e.164 number, which is unique.
others could also
have user(a)sip.domain.com or just plain old user(a)domain.com depending on
how they were resolved.
sip.domain.com example i don't see valid. that can happen, but sip ua
sending the request is somehow misconfigured.
one solution might be a new radius_does_uri_user_exist() function that
would return true if the user part exists and is unique, in which case
the domain would come back in reply item.

that is definitely not the right behavior. dns srv + a lookup results
destination ip address where request it sent, not domain for the request
uri.

kevin,
just to add to your problem, i haven't seen it because i use gws that
can add different domain parts to invites to different numbers.
perhaps you should switch to better gws.

We control gws but don't want to rewrite based on each e164 number as
number series is not divided into groups (per hundred etc.). /Kev/

I think what I'll do is insert the full uri into contact on alias table
for every user then then do a lookup on this at first to rewrite the
ruri (ie. E164 -> uri translation). If the user is not in this table
then it's "unknown" the following failures to lookup location will be
offline subs so they can go to voicemail.
Thanks all for pointers /Kev/
