Hello Users, Good Morning, What are Type of the NAT is used for OpenSER for production , OpenSER is inside the NAT (router/firewall ) 1) I tested with 2 SJ phones and 2 cisco ATA phones, UAC's are in Behind the NAT, UACs are in the Same N/w with one public_address, SJ phone show the NAT type is Symmetric NAT this case is Working Fine, For example : [Behind the NAT1 ] [Behind the NAT2] [Behind the NAT1 ] SJphone -------------------------------> OpenSER---------------------> ATA phone 2) When SJ phones or HardPhones are in Different network behind the NAT of the OpenSER server, here SJ phone shows the Port Restricted core NAT Here media is not is signaling at all , in this Case.... For example : [Behind the NAT1 ] [Behind the NAT2] [Behind the NAT3 ] SJphone -------------------------------> OpenSER---------------------> ATA phone SIP NAT Traversal support only Symmetric NAT , ? Then How to solve this issue ? Please Help ? -- Thanks and Regards Ravi Prakash Sunkara ravi.sunkara(a)hyperion-tech.com M:+91 9985077535 www.hyperion-tech.com Client and Parent company :- www.august-networks.com

Hello, the PIN is sent usually via IVR codes. OpenSER is just a signaling proxy, it doen't interpret media stream. To get auth via PIN, you need a media server in the midle, like Asterisk.

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

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 15 Feb '07

15 Feb '07

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 15 Feb '07

15 Feb '07

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 15 Feb '07

15 Feb '07

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.
