[OpenSER-Users] mi_fifo leaves little openser_receiver_* fifos on the floor
by Chris Heiser 07 Nov '07

07 Nov '07

I have a cronjob that periodically runs openserctl to gather stats out of openser. I've noticed that in my fifo directory, there are anywhere from 1.5 ~ 3k openser_receiver files laying around. Is there something screwy with mi_fifo in v1.2.2-tls that's preventing it from cleaning up after itself? --Chris

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

Hi, Iam too interested in this discussion, can some one explicitly elaborate how iam gonna satisfy all the conditions in a situation whereby OpenSER is relaying to Asterisk for local PSTN calls and to another a voip provider for International PSTN calls, ofcourse this applies for any numeric uri. I have a Sipwise generated config with offnet-termination which i tried to edit route [5] 'invite-find-calee' using t_relay() and rewritehostport conditions, but my concern is the role of LCR module which is supposed to be taking care of the GWs especially in route[7] "Request route invite-to-external", will it gonna disrupt/conflict my set conditions?? ######################################################################## # Request route 'invite-find-callee' ######################################################################## route[5] { if(alias_db_lookup("dbaliases")) { xlog("L_INFO", "Callee was aliased - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); #CHECK WHERE THE REQUEST IS FROM???-edit by me if($fd=="sip.domain") { #FORWARD THEM TO ASTERISK -edit by me rewritehostport("asterisk IP"); #AND THEN TAKE THEM TO REQUEST ROUTE 'base-outbound'-edit by me route(3); } else if(uri=~"Sip:00[0-9]+@"){ #RELAY THEM TO INTERNETIONAL PSTN-edit by me t_relay("IP_of_international_PSTN_ provider"); route (3); } if(!is_domain_local("$rd")) { setflag(20); route(7); } if(does_uri_exist()) { xlog("L_INFO", "Callee is local - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); route(6); } else { xlog("L_INFO", "Callee is not local - M=$rm RURI=$ru F=$fu T=$tu IP= $si ID=$ci\n"); route(7); } exit; } ######################################################################## # Request route 'invite-to-external' ######################################################################## route[7] { if(isflagset(20)) { xlog("L_INFO", "Call to foreign domain - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); route(3); exit; } if(!isflagset(23)) { # don't allow calls relaying from PSTN to PSTN, if not explicitely forwarded if(uri =~ "^sip:[0-9]+@") { # only route numeric users to PSTN if(!load_gws()) { xlog("L_ERR", "Error loading PSTN gateways - M=$rm RURI=$ru F=$fu T= $tu IP=$si ID=$ci\n"); sl_send_reply("503", "PSTN Termination Currently Unavailable"); exit; } if(!next_gw()) { xlog("L_ERR", "No PSTN gateways available - M=$rm RURI=$ru F=$fu T= $tu IP=$si ID=$ci\n"); sl_send_reply("503", "PSTN Termination Currently Unavailable"); exit; } setflag(21); t_on_failure("1"); route(3); } } xlog("L_INFO", "Call to unknown user - M=$rm RURI=$ru F=$fu T=$tu IP= $si ID=$ci\n"); sl_send_reply("404", "User Not Found"); exit; } WBR, LU.

[OpenSER-Users] SIP Topology Question
by Brandon Armstead 07 Nov '07

07 Nov '07

Hey Guys, just looking for some input on this, thanks! Basic Topology ------------------------------- Core Route Servers - Server A, B Registration Server, Collects USRLOC which all reports to the SAME DATABASE. Server C (User A initial registration server) User A -> it will tell me location Server D User A -> it will tell me location Any complications, I should be aware of? So Call Flow will look like so: INBOUND CALL: (Server A|Server B) -> (Server C|Server D) -> (END USER) Now should I be weary of any "lockings" such as a client end such as cable/dsl modem, the ata itself, etc? Thanks. -- Brandon Armstead

[OpenSER-Users] Redundant mysql
by Antonio Reale 06 Nov '07

06 Nov '07

Hi all, I'm trying to setup Openser with two Mysql server configured as Master-Master. Is it possible to configure Openser to read data from the first Mysql server (192.168.1.4) and if that fails to read data from the second Mysql server (192.168.1.5)? If not, which alternatives I have to instruct Openser to use the second Mysql server when the first is down? Thanks in advance. -- Antonio

[OpenSER-Users] [IMC module] What are imc tables for?
by Iñaki Baz Castillo 06 Nov '07

06 Nov '07

Hi, in order to use chat rooms I'd like to manage them just from a web interface that handles imc_rooms and imc_members table, but sincerely I don't know how to use them, I don't see doc about hot to use the tables. What I'd like is to have "fixed" chat rooms without the need of creating them with commands, but via web. Could anyone explain me how to use those tables? Please, explain me with this example: - I want a chat room for domain "domain1.org" and name "chat1". - I want three members for that room: - user1(a)domain1.org - user2(a)domain1.org - other_user(a)other_domain.org Could you fill the tables please? ** imc_rooms table ** name domain flag ** imc_members table ** username domain room flag What is flag for? I suppose it's for features as private/public tables and so. Maybe it's not possible to manage those tables and the only way is using chat commands? Thanks for any help and best regards. -- Iñaki Baz Castillo

[OpenSER-Users] [group module] Realtime in 're_grp' table?
by Iñaki Baz Castillo 06 Nov '07

06 Nov '07

Hi, I need the possibility of users in many groups. This is not allowed by "grp" table where username, domain and grp are UNIQUE key. So It could be valid for me using "re_grp" table and managing numeric groups. But "re_grp" table doesn't allow realtime (if I do a INSERT or UPDATE in the table I need to restat OpenSer). Is not possible to use "re_grp" table in realtime mode? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

Re: [OpenSER-Users] mi_xmlrpc.so: undefined symbol: ConfReadServerFile
by Bogdan-Andrei Iancu 06 Nov '07

Hi Gregorio, Probably you need to link the module against some other lib provided by xmlrpc-c package. Try to use the latest 1.2.x (stable) or 1.3.x (testing) as they have some auto lib detection. Otherwise, you need to change in modules/mi_xmlrpc/Makefile the list of libraries to be used for linking the module. regards, bogdan Gregorio wrote: > > Hi all. > > I have a problem starting ‘mi_xmlrpc’ module.

[OpenSER-Users] maddr in contact
by Allan Chao ( 趙廷睿 ) 06 Nov '07

06 Nov '07

Hi : I have a flow UE -> gateway (use openser and runs proxy mode) ( ip : 192.168.1.2) -> SIP Proxy ( ip: 192.168.1.3), if i have two user , UE1(192.168.1.5) and UE2(192.168.1.6) send REGISTER request to SIP proxy through gateway, but our gateway add a maddr = "192.168.1.2" string in contact header,so the contact in REGISTER becomes <username@ host ; maddr="192.168.1.2">. now , if UE1 send INVITE message to UE2, how does sip proxy to do if receive INVITE message? it will send invite message to UE2 through gateway ( maddr parameter) ? and does openser has support maddr in contact or not . thx. allan

[OpenSER-Users] dispatcher with GeoIP
by Victor Sergeev 06 Nov '07

06 Nov '07

Hello, I'm wondering if its a good idea to tie dispatcher module with GeoIP. The point is to select gateway group depending on IP from which user making a call. In such way you can select the gateway which should be closed to the user. E.g. some users will use USA gateways another EU or Asia gateways. Victor

[OpenSER-Users] Announcement: devel.openser.org available
by Henning Westerholt 06 Nov '07

06 Nov '07

Hello, i'm happy to announce that the 'devel.openser.org' server, sponsored from my company 1&1 Internet AG, is now available. This machine hosts services for developers, but some of them are probably also useful for users: 1. Daily creation of debian builds (etch i386 and amd64) of the trunk for easily testing. 2. A read only svn mirror of the complete repository for better subversion performance especially outside the USA. 3. The build and testing framework "buildbot" for continous monitoring of the status from trunk and branches. 4. Doxygen code documentation with graph generation for better understanding of the code and module dependencies. You'll find at http://devel.openser.org/ the indivdual addresses of the services. This page will probably be moved to www.openser.org after the migration of these server.

Re: [OpenSER-Users] retransmissions after final response
by Vasile Zaharia 06 Nov '07

06 Nov '07

Hi Bogdan, all, I've made more digging and I need your opinion on my findings. Pre-condition: run an AS in forked mode with 2 children. 1. AS sends a request (RQ). 2. AS receives a "408 Request Timeout" reply (RPL) for RQ. 3. After some time (about 30 seconds) AS receives another "408 Request Timeout", initiated at another network node. 4. At this point, you want to send another request from AS. Result: Very often, the replies for the last request cannot be matched with its transaction in "tm" module, so request retransmissions occur. After a few days I've found that in "t_reply_matching" function from "t_lookup.c" file, just before returning (at the end of the function, not in the case when the reply gets matched) T is set to zero (set_t(0)). So, at step 3, the reply cannot be matched with an existing transaction and T is set to zero in a child process. If a reply of the request sent at step 4 gets handled by exactly the child process that last set T to zero, the transaction will not get matched (see t_check() and reply_received() functions), so the retransmission timer will hit => request retransmissions!!! I think the problem is that T is set to zero in t_reply_matching() when a reply cannot be matched. I've changed that to set_t(T_UNDEFINED) and everything seems to work just fine. What do you say Bogdan? Is this change safe? Is this the fix for my problem? Thanks, Sica. ----- Original Message ---- From: Bogdan-Andrei Iancu <bogdan(a)voice-system.ro> To: Vasile Zaharia <sicavz(a)yahoo.com> Cc: users(a)openser.org Sent: Tuesday, October 30, 2007 9:49:38 AM Subject: Re: [OpenSER-Users] retransmissions after final response Salut Sica, So you say that openser does retransmission even after receiving the 200 OK for the request? are you sure it is about the same transaction?

[OpenSER-Users] Cellphones and voicemail
by Chris Heiser 06 Nov '07

06 Nov '07

Trying to send a user's call to their cellphone can be problematic, especially when their phone is off, bad signal, etc... I know some carriers send q931 messages back when a call is redirected (sometimes), but not all do. Is it possible to make a determination in OpenSER (if we know we're sending to a cell phone) that the call was picked up too quickly? That's really the ugly problem. If I could say, "Oh yeah, you're cellphone picked up in less than 1 second, a real person probably didn't do that." and drop that fork, that would be awesome. --Chris

[Serusers] Anyone doing something to handle RFC3326?
by SIP 05 Nov '07

05 Nov '07

We've been looking recently at RFC 3326 (Reason header fields for SIP) primarily to help with logging in some of our UAs. While I know that SER can essentially tack on any header anywhere, I'm wondering if anyone's come up with a solution for handling something like the Call Completed Elsewhere reason tag: Reason: SIP ;cause=200 ;text="Call completed elsewhere" Essentially, this would be sent in a CANCEL message to all clients that did NOT pick up the SIP call. Since SER forks off a separate INVITE to any contact in the location table matching the intended recipient, it would be nice to fire off a reason for a cancel to some UAs which would then know not to bother logging a call as 'missed' in the case of another phone picking it up. I'm sure there's a way to hack this using the current functionality (or if not, a slight modification of current functionality), but if anyone's done it and has a code snippet, that would make life easier.

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 05 Nov '07

05 Nov '07

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?

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.
