[OpenSER-Users] REGISTER Invalid Cseq Number
by tele 09 Oct '07

09 Oct '07

Hi all, I've a problem with a CPE/IAD that sometimes send a REGISTER with same Cseq in the location entry, OpenSER response is "400 Bad Request" with P-Registrar-Error: Invalid CSeq number. This causes the CPE/IAD to disable the voice port. I want disable this kind of check, i've try to set the modparam("usrloc", "cseq_delay", 0) for disable retrasmission check but doesn't work Any other idea to solve this? i've this problem with only this CPE. Thanks! :tele

[OpenSER-Users] [wiki] Adding page about SIP devices supporting presence PUBLISH
by Iñaki Baz Castillo 09 Oct '07

09 Oct '07

Hi, pua_usrloc has an issue with SIP device that publish their state, since the PUBLISH is generated twice: 1) With the REGISTER by pua_usrloc module. 2) With the PUBLISH sent by the device. If for example the user sets "Online" - "Away" status and after that the device refreshes the REGISTER, then its state will just be "Online" (the state pua_usrloc generates). In order to avoid this issue it could be nice to query a BD table looking for the "User-Agent" and just exec "pua_set_publish()" if the device doesn't support presence PUBLISH. The query could be done by regular expressions in order to allow different versions of same device, all of them supporting presence. A doubt I have is: Would be easier store user-agents of devices supporting presence? or not supporting presence? which one list will be shorter? Because it, I'd like to start a page in the wiki containing all the devices "User-Agent" (with regular expression) supporting (or not) presence PUBLISH, and a small script to generate the table after copy&paste the whole list from the web. What do you think about it? Regards. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

Hi there! Can anyone tell me how to get the RealTime Online user status other than using command 'serctl ul show'? Or how can I store the realtime online user status to the MySQL db? Thanks. Cheers, Roa Yu :-)

I've just tried and in this way (UA1-------> NAT--------> PROXY---------> UA2), with UA2 in the same net of SIP proxy, Mediaproxy works.

[OpenSER-Users] CDRTool --Suggestion Required
by srinivas Antarvedi 09 Oct '07

09 Oct '07

Hello users, Actually i want to implement prepaid billing solution to my customers using radius accounting I have gone through the documentation provided with the sources of CDRTool and got confused with all dsn details,connections to mediaproxy ,asterisk,radius,openser. I want to first understand the call flow if using this CDRTool so that i can design mysetup. The present setup i have is 1)openser for authentication 2)Call control using asterisk+asterisk-b2bua in combination with radius Then u may ask why i am after this CDRTool because i was unable to deduct the balance and implement different tariffs using that setup in realtime so i wish to know from you what are different setups i can made using the jumbo CDRTool project so that i can select one and working . First give me suggestion so that i will start with minimal setup -- Srinivas Antarvedi

[OpenSER-Users] SRV load-balancing not balancing evenly?
by Tim Madorma 09 Oct '07

09 Oct '07

Hi, The OpenSER is performing an SRV lookup which returns the following record info: ;; QUESTION SECTION: ;_sip._udp.aimcidfilter.com. IN SRV ;; ANSWER SECTION: _sip._udp.aimcidfilter.com. 180 IN SRV 1 50 5061 spinner.eng.rr.com. _sip._udp.aimcidfilter.com. 180 IN SRV 1 50 5061 bart.eng.rr.com. _sip._udp.aimcidfilter.com. 180 IN SRV 2 50 5061 homer.eng.rr.com. _sip._udp.aimcidfilter.com. 180 IN SRV 2 50 5061 crunch.eng.rr.com. As you can see, the weighting for the two priority "1" endpoints is 50/50 which indicates that the load should be distributed evenly between them. But when I run my test, it consistently sends 75% to spinner.eng.rr.com and 25% to bart.eng.rr.com. Any ideas? ----------- some config info. debug=5 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) maxbuffer=1048576 check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) #reply_to_via=1 children=4 log_facility=LOG_LOCAL4 dns_use_search_list=no dns_servers_no=2 # user="sipproxy" group="sipproxy" #disable_dns_blacklist=yes # FOR TESTING ONLY #dns_try_ipv6=no # FOR TESTING ONLY listen=udp:65.185.232.62:5060 alias=65.185.233.104:5060 # LOAD OpenSER MODULES mpath="/sw/lib/openser/modules/" loadmodule "sl.so" loadmodule "tm.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "acc.so" loadmodule "mi_fifo.so" loadmodule "xlog.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc", "db_mode", 0) # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- modparam("acc", "log_level", 2) modparam("acc", "log_flag", 1) modparam("acc","report_cancels", 1) modparam("acc","failed_transaction_flag", 1) modparam("acc","log_extra", "req_uri=$rU") modparam("tm", "fr_timer", 5) modparam("tm","fr_inv_timer",5) modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo")

[OpenSER-Users] problem with 407 return code
by tloginbr-openser＠yahoo.com.br 09 Oct '07

09 Oct '07

Hi everyone, I'm trying to build one asterisk cluster using openser to route calls to each machine. I followed a few (many) guides and examples on internet but they simple didn't work very well... I'm using the dispatcher module with openser version 1.1.0-9etch1 (running on a debian 4.0). I have two asterisk (trixbox) machines to do load balancing and failover. I can register in my openser machine with my softphone (twinkle). When I place a call to one extension that exists in both asterisks the call goes always to the second ip in the list. Looking in the debug messages I found the following part: 7(7905) DEBUG:tm:t_should_relay_response: T_code=100, new_code=407 7(7905) DEBUG:tm:t_pick_branch: picked branch 0, code 407 7(7905) ERROR:tm:t_forward_nonack: no branch for forwarding 7(7905) ERROR:tm:w_t_relay: t_forward_nonack failed 7(7905) DEBUG:tm:relay_reply: branch=0, save=0, relay=0 7(7905) old size: 555, new size: 474 7(7905) build_res_from_sip_res: copied size: orig:124, new: 43, rest: 431 msg= SIP/2.0 407 Proxy Authentication Required in my understanding that would mean that I need a password of some kind to relay this message to the asterisk box. The funny part is that the call gets completed and goes always to the same box, the second one in the list. If I change the order of the IPs inside my dispatcher.cfg file it starts to go to the other asterisk, that is the 2nd in the list now. After a lot reading in the debug messages and writing some log messages I found out that the invite request is always going down to the failure route. I think that this is because of the call to t_on_failure("1"); inside my if ( method=="INVITE" ) in the main route, that triggers when the code 407 comes from the password reply... thats just one idea. If there is better way to do this (load balance and failover), please tell me, because I'm pretty new to openser, just trying to make it work for the first time here. my openser.cfg has the following lines on it: loadmodule "/usr/lib/openser/modules/dispatcher.so" modparam("tm", "fr_timer", 5) modparam("dispatcher", "flags", 2) modparam("dispatcher", "list_file", "/etc/openser/dispatcher.cfg") if ( method=="INVITE" ) { #dst_select( "GROUP", "HASH METHOD") ds_select_domain("1","4"); t_on_failure("1"); sl_send_reply("100","Trying"); t_relay(); exit(); } failure_route[1] { if(is_method("INVITE")) { ds_next_domain(); t_on_failure("1"); #if the next domain fails too t_relay(); }; } the rest of the file I didn't mess around with it, so its just the default settings.

Have you tryied to call from UA1 (behind your NAT) to other device out of your LAN? MediaProxy (if it well configured) should work in that case. In case caller and called behind the same call, you explicitely **need** to allow direct RP in openser.cfg by matching $si with $dd (if pulbic source address and destination address is the same don't apply SDP fix). But if you haven't configured it explicitely then maybe your conf is worng. -- Iñaki Baz Castillo ibc(a)in.ilimit.es _______________________________________________ Users mailing list Users(a)openser.org http://openser.org/cgi-bin/mailman/listinfo/users
