[Serusers] delay to write things in DB when using serctl

by Ricardo Carvalho

When I add with serctl some alias to the DB, only after some time it appears written in the aliases table of DB. How can I force that to be simultaneously written in DB? Any parameter I have to tune in ser.cfg? Regards, Ricardo.

[Users] Re: Request for discussion: t_relay() internal error processing

by Mark Kent

>> 2) t_relay will return several error codes: >> -1 = no transaction created -> need to use sl_* functions >> -2 = transaction created, relay failed -> may destroy If I understand this correctly, the difference between these two return codes really has to do with who it is that cares about it... -2 relates to this exact call, at this exact moment, chances are the very next call the openser box handles will be OK. It looks to me like -1 means serious trouble, for the entire call switching platform. It sounds like it could happen because of a resource shortage (memory), possibly because of a bug in openser, or a bug in the openser.cfg. If you get -1 once, then the chances that you'll get the same code on the next call are very high. Let's say we've run out of memory. Then, what tools are available at the openser.cfg script level that can handle this? Is there a way to force some internal garbage collection? Or to do a warm-restart (e.g., trash all transactions, but not registrations)? My point here is this: if I'm right about -1 meaning serious trouble that is likely to mean serious problems from now on, then this is a more general problem than just t_relay, and much bigger than just handling this one call or a call to one particular neighbour. It's true that the application may halt and catch fire, but there are plenty of errors that are catchable by openser and the larger question seems to be: what do we do then? If there were script-level tools that could be used to try to manage the failure, possibly clean up (in a large way) and try to keep going, then maybe we should have openser_failure route blocks that the user can register with openser to handle various errors. Thanks, -mark

[Users] Request for discussion: t_relay() internal error processing

by Bogdan-Andrei Iancu

Hi all, there are some topics largely discussed lately on the mailing list; in order to fix them problems first we need to find a solution for logical point of view - and here I think that several opinions are better than one :) In order to have failover based on serial forking, it is mandatory to be able to detect from script if the initial t_relay() fails. The problem is that now t_relay() masks any error by internally generating an error SIP reply. Of course, it can be internal errors (like lack of memory), msg errors (parse errors) or transport errors (DNS failed, send/connect failed, etc). Now, disabling the auto replying in case of error is not a problem. The problem is how to handle the errors from the script; two make distinction between the error classes a listed above will not be the purpose of this email ( I will open another one for this ;) ). What is important here is to be able to properly resume from the point were the error popped up. What I mean is: the t_relay() function builds the transaction and sends the requests. If the error occurred during transaction creation, from script, you will had to use only stateless functions to send err. replies. If the transaction was already created and the error popped up during relaying stage, you will need from the script to take care of the transaction and either destroy it, either reply it. Based on this, here is what I suggest: 1) have a new param for disabling the auto reply in t_relay() 2) t_relay will return several error codes: -1 = no transaction created -> need to use sl_* functions -2 = transaction created, relay failed -> may destroy transaction, reply via TM with error, trigger failover. any comments on this ? regards, bogdan

[Serusers] No calls shown in serweb under accounting tab

by Chahn John Kim

Sorry for double posting. I forgot to put subject line in previous posting. Hi, all. I just installed serweb and it is working however there is are no calls shown under "accounting" tab, saying "no calls". Mysql table has call records with matching flag set in ser.cfg. Records seem to be correct for numerous test calls made. It just that serweb doesn't seem to pull those records out of mysql at all. Any idea where I should look at? Thanks in advance. -- Chahn John Kim

[Serusers] prevent a dialled username without dialling the domain to ring a phone registered with that username

by Ricardo Carvalho

How can I prevent a dialled username (without dialling the domain) to ring a phone registered with that username? I pretend to use a multi-domain architecture where apart from aliases of users, only dialling with username@domain will ring registered phones. Thanks, Ricardo.

[Users] Freeradius dictionary additions..

by nick

When I add my dictionary.openser to Freradius v 1.0.1-3 on Centos 4.3, and after following all the steps outlined on the webpage: http://www.openser.org/docs/openser-radius-1.0.x.html When I get to testing the configuration, radiusd -X i get this: read_config_files: reading dictionary Errors reading dictionary: dict_init: No ATTRIBUTE "Sip-Method" defined for VALUE "Other" Errors reading radiusd.conf Unfortunately freeradius.org is now a parked domain (seems like a rather large oversight on their part...) so I can't ask them.. Has anyone here ever seen an issue like this? BTW, I'm using openser 1.1.0-notls compiled from source. Not that seems to apply here though.
