Re: [Users] Send Call using authentication

by Bogdan-Andrei Iancu

Hi Jobson, does your ITSP require digest authentication? if so, you better take a look at uac module.

Re: [Users] Message dispatching to local scripts - problem in modifying the RURI

Dan, the env. vars. are also available in 1.1.x : http://www.openser.org/docs/modules/1.1.x/exec.html#AEN33 the buffer that is sent to the script by exec_msg() is the original received buffer, so it does not contain any of your script changes. regards, bogdan Dan-Cristian Bogos wrote: > Hi Bogdan, > > Till 1.2.x will be stable, I have to use 1.1.0 in my production, > therefore I cannot use the new features from 1.2.x (even if I am keen > of doing this). > > About the external script, I am passing the full message to the > external script, and I have considered that this is after I have done > the ruri modification through avps.

[Users] Aliases and attempts from UA's to register their aliases

by Andreas Sikkema

Hi, I'm working on extending my OpenSER configuration to allow a user account to have one or more aliases. User A is reachable by calling A, but also using alias B or C. I have this working for calls to the UA, but I'm having problems with registration attempts from A and calls from A to other UA's or PSTN where it wants to send B or C as outgoing CLI. For some reason, all UAs I've seen so far need to register their aliases to be able to send an alias as outgoing CLI. My OpenSER config uses the following to check authenticate the user (from an old SER example: if (!www_authorize("domain", "subscriber")) { www_challenge("domain", "0"); exit; } if (!check_to()) { log("LOG: To Cheating attempt\n"); sl_send_reply("403", "That is ugly -- use To=id in REGISTERs"); exit; }; When a UA tries to register an alias the www_authorize() succeeds, because the UA sends the correct authentication data for A, but uses the alias B or C in the To and From headers so check_to() fails with the error that B or C is being spoofed. I (OpenSER) know that B and C are aliases of A, but how do I make this registration logic accept that and send a 200 OK message back? (I also don't want to save the registered alias in the location table, but that part I know how to do, I think). The calls using outgoing CLI of the alias have I think the same problem where the From header has an alias where check_from() expects the data for A. I think the solution for this would be something comparable to solving the registration problem, correct? Thanks! -- Andreas Sikkema

[Users] Message dispatching to local scripts - problem in modifying the RURI

by Dan-Cristian Bogos

Guys, I've got a problem with MESSAGE processing. I am trying to push an avp to replace $ru before dispatching the message to a local script. I can log the modification of the ru successful with xlog, but, as soon as I will send the message to the local script, it looks like the changes are dropped and to the script will be presented the original message. Any ideea why? Are the changes not applied for messages not forwarded out, and dispached locally? In my routing I have: if (avp_check("$avp(s:message_dst)","re/sip:00.*/g")) { avp_subst("$avp(s:message_dst)/g", "/sip:00(.*)/sip:+\1/"); xlog("I have changed the destination from sip:00 into sip:+ and avp is $avp(s:message_dst)"); }; if (!avp_pushto("$ru","$avp(s:message_dst)")) { sl_send_reply("403", "Cannot set destination from AVP"); exit; }; exec_msg("echo_message"); t_newtran(); t_reply("200", "OK"); t_release(); exit; I appreciate any kind of advice. Thxs, Dan

[Users] Transactional Stateful Proxy

by Michel Bensoussan

Hello In the OpenSER feature list it says that it support transactional stateful SIP Proxy processing. Does that mean Call Stateful? I mean if a session is established and a UA sends a re-INVITATION (for example to add video to voice) will the OpenSER Proxy will be informed of this new transaction ? And eventually can it disallow this new transaction (if there is no enough resources like bandwith)? Regards, Thanks. -- Michel Bensoussan Extricom Ltd.

[Users] radius authentication

by Stefano Capitanio

Ciao! I'm trying to authenticate using Radius. I've installed radiusclient-ng 0.5.2 i've configured radiusclient.conf with the IP address of the radius server. I've configured SER with: ... modparam("auth_radius", "radius_config", "/etc/radiusclient-ng/radiusclient.conf") ... if (method=="REGISTER") { if (!radius_www_authorize("example.it")) { www_challenge("example.it", "0"); exit; } save("location"); } but it doesn't work: there seem to be a problem in the client because there is no IP Packet that goes out directed to the radius server... in the log of SER i have no errors... thank you for any help, Stefano

[Users] Method of tracking dead accounts?

by Nick De Cristofaro

We are looking to find a way to audit the accounts on our SER that haven't been used in a long time so we can decide if they are dead and we can remove them, hence re-use their PSTN numbers. I'm not sure if there's any module built in that could do this? Any ideas? There's 4000 accounts approximetely. Thanks Nick

[Serusers] user aliases in ottendorf??

by tzieleniewski

Hi !! Is there still some mechanism for user aliases in ottendorf?? I ask because when I add a user through serweb it adds two records to the uri table one for a canonical name and the other for numeric address. What has to be done (what function called in ser.cfg) so that whenever user will be called on that numerical name there will be a possibility to forward the call to him, like it was previously done in ser 0.9 with lookup("aliases")? Bests -Tomasz
