Re: [OpenSER-Users] Openser as a conditional stateless proxy

Your logic is correct, you can either check the From: header or the request URI or any other part of an incoming SIP message to make the routing decision. A simple example looks like: if (is_method('INVITE')) { # check if from URI domain equals 911operator.com if ($fd == '911operator.com') { # relay stateless using request URI forward(); exit; } else { # relay statefull using request URI if (!t_relay()) { sl_reply_error(); }; exit; } } Please always CC users(a)lists.openser.org so that others can take advantage of the discussion. /Christian > > Thanks again, > Padmaja > > ----- Original Message ----- From: "Christian Schlatter" <cs(a)unc.edu> > To: "Padmaja" <padmaja.rv(a)vodcalabs.com> > Cc: <users(a)lists.openser.org> > Sent: Monday, November 05, 2007 4:53 AM > Subject: Re: [OpenSER-Users] Openser as a conditional stateless proxy > > >> Padmaja wrote: >>> Hi all, >>> >>> Can any one tell me if the same running instance of Openser can be >>> configured as a stateful proxy for some user accounts and for some >>> numbers like emergency services, it acts like a stateless proxy, just >>> forwarding the request to the destination? >> >> Yes, it only depends on what forwarding function is used in the >> routing script: >> >> - t_forward(..) --> stateless >> >> - t_relay(..) --> stateful >> >> /Christian >> >

[OpenSER-Users] proper call tear down

by Miles Scruggs

Hi, This is probably more SIP related than openSER, but I'll ask it here anyway When we were at VON I brought up the subject of accounting and verifying proper call tear down, and it seems the ideal solution from a sip perspective is RFC 4028 (SIP session timers) which tracks the actual sip session with the UA. What I'm starting to realize is that support for this is very limited and I haven't found much evidence if any in the devices where network failures are most likely to occur ATAs and end user devices. This seems to leave me relying on the media stream, but this also has its issues with network issues occurring when calls are placed on hold. Does anyone have any good suggestions for accurate accounting when dealing with end users, or is what I described as good as I'm going to get, until I find some solutions that support 4028?

Re: [Serusers] [Serdev] need help - Call Forwarding

by Jiri Kuthan

This should in (poor) theory work. I would check by watching the mysql port number traffic what data gets actually fetched before making the next step.

Hi All, We are using SER-0.9.6. We want it to be configured in a way that it can have two interfaces towards two different application. One interface will be over TLS and another will be over UDP.

[OpenSER-Users] gateway aspect of LCR module

by Miles Scruggs

Hi guys, Great to meet many of you this week at VON and looking forward to getting together again soon. We have a question about the gateway aspect which is part of the LCR module. We are needing to route to various carriers which the module handles great, but we are trying to figure out if there is an elegant way to handle the situation where a carrier provides us with multiple proxies. For instance if carrier A provides proxy1 and proxy2, carrier B etc.... When we get the AVP back which will be our stack to do serial forking the sequence is dependent on the proxy response (or lack of response) For instance if we get a 400 error back from either proxy there isn't much use in trying the other proxy we need to more along to a completely different carrier. For 500 errors or time outs will continue on using the same carrier. The obvious ways to do this: to abandon the gateway aspect all together and just build logic which we could use to process what would appear to be a multi demential array instead of single diminutional array. I'm just writing to see if there is a nice out of the box way to handle this scenario, also if not, is this something which developers would be interested in having added to the module?

[Serusers] Damaged message body

by Stefan.Brozinski＠materna.de

Hello everybody there is a bug in SER that removes the last byte from a message body if this happens to be a binary zero. This may be the case when the Content-Type is something binary (i.e. *not* using "Content-Type: text/something"). The bad code is in udp_server.c. It is present in SER 0.9.x a well as in 2.0. I have reported it in the bug tracker as SER-324 and attached a comment which points out the bad section of the code. How shall I proceed to fix this bug? Best regards Stefan

[OpenSER-Users] Reg. Subscriber table

by Padmaja

Hi all, I am using the openserctl command to add users to the Openser database and I can verify if these numbers are added to the Subscriber table in the mysql database.However, if I try to look into the Subscriber table through Webmin, I do not see all the users but only a few. What should I do to reflect all the users through webmin as well?
