[Serusers] SIP Accounting Module problem
by POON Ben 23 Mar '07

23 Mar '07

Hi folks, I'm trying to get my accounting services working, but am having trouble doing so... I am using the sample ser.cfg file, and am having a problem loading the acc.so module. In the ser.cfg file, I try added the line: loadmodule "/usr/sfw/lib/ser/modules/acc.so" to the bottom of the loadmodule section. I haven't done any modparam or scripting yet, even so, when I restart the ser service, I get: Starting SER : cat: cannot open /var/run/ser.pid. If I comment or remove the loadmodule line, ser will load again. Is there anything else I need to add or configure before loading this module? I went to /usr/sfw/lib/ser/modules to make sure acc.so is there, and it is. Any help is greatly appreciated. Thank you very much. Ben

[Users] OpenSER not sending responses to IP in via header
by Tim Madorma 23 Mar '07

23 Mar '07

Hi, I have an OpenSER behind a BIG IP load balancer. The scenario is as follows: 1) The UAC will initiate the call with an INVITE that has the REQ URI set to the IP of the BIG IP. 2) The OpenSER has an alias configured for the IP address of the BIG IP so it receives the incoming INVITE, but when it sends a 100 response, it does not send it to the UAC address that is specified in the VIA header, rather it sends it to the source IP (which is the IP of the BIG IP load balancer). This is undesirable. 3) After the UAS receives the proxied INVITE, it responds with a 100, then answers with a 200. 4) When the OpenSER receives the 100, it forwards this back to the BIG IP load balancer! First, I am surprised that it fowards a 100 at all, and second it is undesirable to send any responses to the BIG IP load balancer since the via header indicates the IP of the UAC. 5) When the OpenSER receives the 200, it forwards it back to the BIG IP also.. again, I don't know why it isn't sending to the IP address of the via - which is that of the UAC. Any suggestions would be most helpful. Here are my related openser.cfg settings: # LOCAL IP ADDRESS AND PORTS listen=65.185.232.62:5061 listen=65.185.232.62:5062 listen=65.185.232.62:5063 # IP ADDRESS AND PORTS OF THE BIG IP LOAD BALANCER alias=65.185.233.104:5061 alias=65.185.233.104:5062 alias=65.185.233.104:5063 thanks, Tim

[Users] OpenSER sometimes forwarding 100 response
by Tim Madorma 23 Mar '07

23 Mar '07

Hi, I'm using version 1.2 of OpenSER. After proxying an INVITE from a UAC to a UAS, the UAS replies with a 100 Trying. *Sometimes* the OpenSER forwards this 100 Trying to the UAC. Any idea how to disable this? I think this can be done using onreply_route, but it seems that a received 100 should not be forwarded by default. thanks, Tim

[Users] reason of interlocking with Asterisk server
by 김형선 23 Mar '07

23 Mar '07

Hello. I think that some sites use OpenSER with Asterisk server. But Why? (for accounting? or supplementary service?) Aren't they same? In conceptionally, OpenSER is central VoIP server, and Asterisk is IP-PBX for apart site. right? What is the structure of service being applied, in generally? OpenSER, Asterisk,... What is the role of them? thank you. 새로운 기부문화의 씨앗, 해피빈

[Users] OpenSER performance tests
by Bogdan-Andrei Iancu 22 Mar '07

22 Mar '07

Hi everybody, based on the newly 1.2.0 OpenSER release, we ran some tests in order to give some realistic numbers about the performances of OpenSER. I think it is a very useful information for our community or other interested people. For more, please refer to the news bulletin: http://www.openser.org/mos/view/News/NewsItem/OpenSER-1.2.0---Perfomance-Te… or directly to the tests results web page: http://www.openser.org/docs/openser-performance-tests/ regards, bogdan

[Serusers] ACK for non-2XX not record-routed
by Emmanuel Hislen 22 Mar '07

22 Mar '07

Hi, I've been using SER (0.9.6) as a Proxy doing Loose Routing between 2 endpoints. If I place a call I can see how the ACK for the 2XX response to the INVITE is properly handled (Route header removed, Record-Route inserted). Now with the call still up, I do a re-INVITE which is rejected with a 415. The re-INVITE request sent by UAC contained a Route header, as it was an in-dialog request in a record-routed dialog. Now as per RFC3261 section 17.1.1.3: If the INVITE request whose response is being acknowledged had Route header fields, those header fields MUST appear in the ACK. This is to ensure that the ACK can be routed properly through any downstream stateless proxies. My UAC complied with the above, but SER seemed to choke on this: whereas the ACK for 2XX was successfully routed by SER in the original INVITE, the ACK for non-2XX (looking exactly the same: same Request URI, same IP destination, same Route header, ... different Via branch of course) is not handled properly: yes the ACK reaches UAS but it still has the Route header in it, and no Record-Route was added. And I'm guessing that if there had been another proxy in the Route Set on the way to the UAS it would have been bypassed. SER traces for ACK-2XX: > 0(13574) ===> Loose Routing logic... > 0(13574) parse_headers: flags=-1 > 0(13574) DEBUG: t_newtran: msg id=89 , global msg id=88 , T on entrance=0xffffffff > 0(13574) parse_headers: flags=-1 > 0(13574) parse_headers: flags=60 > 0(13574) t_lookup_request: start searching: hash=41794, isACK=1 > 0(13574) parse_headers: flags=28 > 0(13574) DEBUG: t_lookup_request: e2e proxy ACK found > 0(13574) parse_headers: flags=4 > 0(13574) DEBUG: totag for e2e ACK found: 0 > 0(13574) SER: forwarding ACK statelessly SER traces for ACK-non-2XX: > 0(13574) ===> Loose Routing logic... > 0(13574) parse_headers: flags=-1 > 0(13574) DEBUG: t_newtran: msg id=92 , global msg id=91 , T on entrance=0xffffffff > 0(13574) parse_headers: flags=-1 > 0(13574) parse_headers: flags=60 > 0(13574) t_lookup_request: start searching: hash=41807, isACK=1 > 0(13574) DEBUG: RFC3261 transaction matched, tid=007d7195499e33a1 > 0(13574) DEBUG: t_lookup_request: transaction found (T=0xb616ae48) > 0(13574) DEBUG: cleanup_uac_timers: RETR/FR timers reset > 0(13574) DEBUG: add_to_tail_of_timer[2]: 0xb616ae90 > 0(13574) DEBUG:destroy_avp_list: destroying list (nil) > 0(13574) receive_msg: cleaning up This doesn't seem right, am I missing something here?
