[Serusers] Logging weirdness with Aliases.

Thanks, Greger, that actually gave me an idea of how to solve it but in a completely different way.  

I was playing with your idea, which works really well.... the modified query comes to: 

SELECT t1.from_uri as Caller, t1.to_uri as Callee, TIMEDIFF(t2.time, t1.time) as Duration, t1.time as CallDate, a1.username as alias, a1.contact as myuser FROM acc t1,acc t2, aliases a1 WHERE t1.sip_callid=t2.sip_callid AND ((t1.fromtag=t2.fromtag AND t1.totag=t2.totag) OR (t1.fromtag=t2.totag AND t1.totag=t2.fromtag)) AND t1.sip_method='INVITE' AND t2.sip_method='BYE' AND (t1.to_uri LIKE '%<username>%' OR (t1.to_uri=a1.contact AND a1.contact LIKE '%<username>%')) AND (select count(*) from acc where sip_callid=t1.sip_callid and sip_method='INVITE' and from_uri LIKE '%<username>%')=0 GROUP by t1.time ORDER BY t1.time DESC;

Of course, this doesn't show anything actually useful in the 'alias' column because it selects the same entry once for each alias (a cross join), and with my 'group by t1.time' to limit that to one entry per time slot, it ends up displaying just the first alias in the table... but this is really almost EXACTLY what I wanted. I could discard that field completely, and still, with that query, show who called the user and when. An elegant solution, thank you. 

However, I decided to add one minor step to it in order to, well, make things more complex, really.  

I grab a list of aliases for a particular user and place them into an array... then I build the query string based on that list:

SELECT t1.from_uri as Caller, t1.to_uri as Callee, TIMEDIFF(t2.time, t1.time) as Duration, t1.time as CallDate FROM acc t1,acc t2 WHERE t1.sip_callid=t2.sip_callid AND ((t1.fromtag=t2.fromtag AND t1.totag=t2.totag) OR (t1.fromtag=t2.totag AND t1.totag=t2.fromtag)) AND t1.sip_method='INVITE' AND t2.sip_method='BYE' AND (t1.to_uri LIKE '%<username>%' or t1.to_uri LIKE '%<alias1>%' OR t1.to_uri LIKE '%<alias2>%'... etc) AND (select count(*) from acc where sip_callid=t1.sip_callid and sip_method='INVITE' and from_uri LIKE '%<username>%')=0 ORDER BY t1.time DESC;

What this ends up giving me is a list of calls to that user, but formats them in such a way that I can show not only where the calls came from, but to which alias they went (all the aliases are DIDs, so this may be helpful for some people). 

Thank you thank you thank you again. Without your help, I probably just would have given up. :)

We do logging using the ACC table... not for billing purposes, but so userscan have a look at their logs (billing CDRs are kept on Asterisk and areaccurate and good). The problem is this... Our current query to display incoming calls looks like this:SELECT t1.from_uri as Caller, t1.to_uri as Callee, TIMEDIFF(t2.time, t1.time)as Duration, t1.time as CallDate FROM acc t1,acc t2 WHEREt1.sip_callid=t2.sip_callid AND ((t1.fromtag=t2.fromtag AND t1.totag=t2.totag)OR (t1.fromtag=t2.totag AND t1.totag=t2.fromtag)) AND t1.sip_method='INVITE'AND t2.sip_method='BYE' AND t1.to_uri LIKE '%<username>%' AND (select count(*)from acc where sip_callid=t1.sip_callid and sip_method='INVITE' and from_uriLIKE '%<username>%')=0 ORDER BY t1.time DESC;It's a complex query, but it works quite well... UNTIL you put aliases intothe picture. When using aliases, all transactions in and out in the logs are written as th!
 euser's alias, and not the user himself. This makes sense, but it's giving me aheadache for logging. If I attempt to use a lookup("aliases") command torewrite the URI for the purposes of logging, the BYE message vanishes. So I guess my question is: is there an elegant solution for this, or cansomeone give me a way to go through each and every user's alias, create atable like the one above, and then somehow merge the tables, ordered by timestamp?I have quite taxed the limit of my SQL knowledge, so I'm at a loss.

Why does that happen? Can someone fill me in on that?It's strange... just when you think you have a handle on all of this,something comes along you just completely don't understand.N.On Wed, 28 Jun 2006 18:37:29 -0400, sip wrote   Okay... help me visualise something.

 ow, as far as I can tell, SER is doing exactly what it's supposed to b
e doing, but I can't figure out how to get it to do something different.I have an accounting section (my log flag is 1) that looks like this:if((method=="INVITE" && !has_totag()) || method=="BYE"){ setflag(1);};Basic, simple logging section. But when someone calls through from a DID to an alias in the aliases table, it of course logs the sip_to as the alias.Fine, I thought. I'll just add a lookup("aliases") before the setflag and all will be well, right? No. Then it doesn't seem to log anything at ALL.So what I'm trying to figure out is how to get SER to log a call coming into an alias as a call to the user who's aliased.I.e. a call is coming in from 1010 at remote.proxy.com to 9999 at proxy.com (which is really an alias to user 1234 at proxy.com).  Right now, SER is logging in the acc tables that the call went to sip:9999 at proxy.com.I want to have it log that the call went to 1234 at proxy.com and NOT that it went to the alias.This:if((method=="INVITE" && !has_totag()) || method=="BYE")!
 { lookup("aliases");  setflag(1);};gets me nothing at all.Ideas, anyone? I'm stumped. I'm sure it's something drastically simple that I'm just not getting.N._______________________________________________Serusers mailing listSerusers at lists.iptel.orghttp://lists.iptel.org/mailman/listinfo/serusers    _______________________________________________Serusers mailing listSerusers at lists.iptel.orghttp://lists.iptel.org/mailman/listinfo/serusers
