[OpenSER-Users] Radius Acct Syntax Error?
by Drix Tabligan 18 Feb '08

18 Feb '08

Hi, A quick help from anyone please? I've compiled Openser to support radius accounting and did the necessary installations already. Freeradius is running and can do accounting and auth already when tested. I'm having a problem starting Openser 1.2. The output shows... --------------- 0(11900) set_mod_param_regex: acc matches module acc 0(11900) set_mod_param_regex: found <service_type> in module acc [/ usr/local/lib64/openser/modules/] 0(11900) set_mod_param_regex: acc matches module acc 0(11900) set_mod_param_regex: found <radius_config> in module acc [/ usr/local/lib64/openser/modules/] 0(11900) parse error (224,21-22): syntax error 0(11900) parse error (224,21-22): ERROR: bad config file (2 errors) --------------- If I comment out the modparam("acc", "radius_config", "/usr/local/etc/ radiusclient/radiusclient.conf") below, Openser runs. A snip of the openser config... --------------- modparam("acc", "acc_sip_code_column", "sip_code") modparam("acc", "acc_sip_reason_column", "sip_reason") modparam("acc", "service_type", 15) modparam("acc", "radius_config", "/usr/local/etc/radiusclient/ radiusclient.conf"); modparam("acc", "radius_flag", 0) modparam("acc", "radius_missed_flag",0) modparam("acc", "multi_leg_info", "src_leg=$avp(i:901);dst_leg=$avp(i: 902)") modparam("acc", "radius_extra", "Sip-RPid=$avp(s:rpid); \ Sip-Src-IP=$si; \ Sip-Src-Port=$sp; \ Divert-Reason=$avp(s:divert_reason); \ X-RTP-Stat=$avp(s:rtp_statistics); \ From-Header=$hdr(from); \ User-Agent=$hdr(user-agent); \ Contact=$hdr(contact); \ Event=$hdr(event); \ SIP-Proxy-IP=$avp(s:sip_proxy_ip)") -------------- Which means that radius accounting was compiled in as the other parameters doesn't spew the error. The radiusclient.conf and dictionary files are essentially untouched except for the necessary changes on the shared secret and ip addresses for the radius config. Openser, Freeradius and Radiusclient are running on the same box under FC7 64bit. Thank you in advance for your help... Drix

Re: [OpenSER-Users] Failover using NAPTR/SRV
by Douglas Garstang 18 Feb '08

18 Feb '08

Ok, so rfc3263 defines what the user agent should do when a 503 reply, or no reply is received. What about the rest of the possible SIP replies? We use several different ITSP's. I just checked the logs for our last 50,000 calls from all of them and there was a total of 19 different replies received. They are: 200,400,401,403,404,408,410,480,484,486,487,488,500,501,502,503,504,603 Some of these can occur under normal conditions, 486 is busy for example, or 487 is generated by a CANCEL. What about the rest? Most of the rest can be classified as error conditions. Are you saying that if another error condition besides 503 is received that you don't do failover? Why?

Hi All I would like to know if anyone can state the most important differences between openSER and SER in terms of features. I am not very interested in CPU and RAM consumption I would like to know if there are any differences between the two servers in terms of functionality. Thanks

[OpenSER-Users] Survey for new mailing list
by Bogdan-Andrei Iancu 18 Feb '08

18 Feb '08

Hi all, I the last year there was a good progress on the project policy regarding releases (major and minor). Still, from my experience as booth developer and user of openser, I feel the need for way to promptly and focused inform the users of openser about the fixes, especially critical fixes, that require immediate update. Many project have lists where you can subscribe in order to get notification for critical bug or security fixes. Currently, for openser, if you are not subscribed on devel list and if you are not "good" enough in "decrypting" the commit logs, you may miss important fixes you may want to update. I think is our duty as project to inform the users about the discovered flows in the stable versions. My suggestion is to create a new mailing list where, who is interested, will receive notifications when something critical was fixed in the stable versions of openser. Maybe a new list (like "alerts(a)lists.openser.org") where a developer, after making the fix, can issue (if considered important) an update alert for the interested people : Severity: Affected services/modules: Description: Rev number where the fix is available: How to update: ? I come to this as right now I'm working at two major fixes in the stable versions affecting two important serviced - user location and accounting. And I bet a lot of people will be interested in this in order to update their installations. Please let me know your thoughts on this. Best regards, Bogdan

[OpenSER-Users] TM-module and ACK to 2xx (doesnt terminate txn?)
by Taisto Qvist 18 Feb '08

18 Feb '08

Hi Guys, I'm having trouble with my ACK's on 2xx, and reading about the TM-module, it says for *t_check_trans()* : *ACK request - *true if the ACK is a local end-to-end ACK for an existent INVITE transaction. To me, that sounds like a contradiction in terms, since there is (rfc-wise) no transaction left after 2xx has been proxied through, and the ACK starts coming in(because of record-routing). (and my script's ACK-logic for consuming ACK for 3++ also eats the ACK for 2xx :-( ) Does the TM module not follow the rfc-described termination of invite-txn's? Then how long does the transaction live after 2xx has been forwarded? How come its implemented this way? If this is so, then how do I differentiate between an end-to-end ACK for 2xx, and a 3++ hop-by-hop ACK? I have to use flags and stuff? (Havent got that far yet in my openser understanding...) Regards Taisto Qvist Ip-Solutions.se

[OpenSER-Users] Can we have different session identifiers for one session?
by Vikas CG. 18 Feb '08

18 Feb '08

HI all, Can we have different session identifiers for one session?? Scenario: For INVITE (Offer) im getting 200 OK (Answer). And it will have one session id at "o" line in sdp. I will send re-INVITE with different session id. Is it possible??? In RFC they have suggested to use unique identifier for session, But some sip hard phones are sending different session id's is it possible??? Plz suggest how to handle this scenario. Thanks, Vikas C.G.

Re: [OpenSER-Users] [OpenSER-Devel] How to stop OpenSER from replying with 100 Trying?

I assume that you've configured your SEAS server correctly. Please look into the log messages of your server to get some hints why this fail. You can also activate logging to the console with a config parameter if you like. If you don't spot any problems in the output, increase the debug level to get more hints. Please don't post this type of questions to the devel list. Thank you! Henning

[OpenSER-Users] Question abour acc and failed INVITEs in 1.3
by Phil D'Amore 18 Feb '08

18 Feb '08

Hello: I have a situation where I am trying to send an INVITE to two different gateways serially. If the first gateway fails, and the second one succeeds, I would expect to see a record for the failure, and a record for the success. At least, this is the way 1.1 did it. In 1.3, I only see a record for the final success. I have both my db_flag and db_missed_flag set. Does anyone have an idea why I would not see the failure? Something new in 1.3? Thanks, Phil

Re: [OpenSER-Users] SIP Trunk doesn't response to 200OK with an ACK
by Eric Phetteplace 17 Feb '08

On their end, they see they send an ACK after I send an OK. I sent them a tcdump file of my traffic during the session. Any suggestions? Eric
