Not getting packets between peers!
by Yurisbel Jimenez 29 Dec '13

29 Dec '13

Problems getting audio when call from outside mi LAN. Both peers in my LAN perfect. One peer in my LAN, and another outside in the cellphone company internet; the one outside don't delivery any packet to the one inside my LAN Them can see each other and try to talk but the packets sended to the other party get lost. No one receive anything. Restarting services for rtpproxy and kamailio after every try. Here is my configuration on /etc/default/rtpproxy file: USER=kamailio GROUP=kamailio CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" EXTRA_OPTS="-l 72.28.208.16 -s udp:localhost:7722" Here my configuration on kamailio.cfg file corresponding with NAT: #!ifdef WITH_NAT # ----- rtpproxy params ----- #modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_sock", "unix:/var/run/rtpproxy/rtpproxy.sock") # ----- nathelper params ----- modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) #!endif Ports opened in my router for Kamailio: udp:35000-65365, udp-tcp:5060, 5061 I know this is personal information but this server is a case study. I'm Trying to learn from you all and if it's possible contribute in the future with some knowledge. Two users for you to test: user name: support domain: uscallfree.com password: support Not TLS yet user name: master domain: uscallfree.com password: master Not TLS yet If one of you wants to try what happen when calls from one peer use that one above, my user name always active is admin(a)uscallfree.com. I know it's not working but maybe helps to determine what it's happening. admin(a)uscallfree.com active 24 hrs. in my nexus 4 native SIP profile configuration. Thank for the help provided here in the mailing list. You all rocks

Need a clue!
by Yurisbel Jimenez 28 Dec '13

I was trying for too long right now to have a complete call between to parties outside mi local network but they can start the call and nothing its heard. I think it’s because my network it’s behind a NAT but I’m already configure the “rtpproxy” to use my external IP not the one on my private network and still not working. Kamailio and RTPPROXY are communicating through IP and port udp:127.0.0.1:7722 Local calls works fine but the problem its with one or both parties outside the local network. Register and keep location outside the networks works but don’t ear a sound and in the statics the is no packets travelling between them both. Thanks you all.

critical:: Presence related query
by Piyush.Bansal＠relianceada.com 28 Dec '13

28 Dec '13

Hi, I am using iptel SER for quite a long time. Currently am using presence sharing mechanism of SER. While testing the same it is observed that SER doesn't send partial NOTIFY message i.e. it always sends NOTIFY with complete rlmi doc and pidf for all the buddies. Isn't it possible to send NOTIFY messages only with the pidf of the user who is changing the presence not all?? I checked the code and found there is no support of partial notification (fullState is always set as true). Is there any new version of ser available where this issue has got resolved??? Please help, its urgent.

Missing destinations in CDRTool but calls are ok
by Teddy Rabary 26 Dec '13

Hi and Merry Christmas, I don't know if I can ask my problem here because it's about CDRTool not kamailio. I use kamailio+mediaproxy+callcontrol+cdrtool+freeradius-xs, all calls are OK, the balance is updated after each calln, and i have start/bye on freeradius. All seems ok but after each call I receive from cdrtool something like this, for example when I call to Germany (00491525XXXXXXX) Dec 25 17:43:53 billing cdrtool[11656]: Dec 25 17:45:01 billing cdrtool[17062]: Error: cannot find destination id for 491525XXXXXXX of customer = '', total destinations = 0 Dec 25 17:45:01 billing cdrtool[17062]: Error: cannot find destination id for 491525XXXXXXX of customer = '', total destinations = 0 Dec 25 17:45:01 billing cdrtool[17062]: Error: cannot find destination id for 491525XXXXXXX of customer = '', total destinations = 0 Dec 25 17:45:01 billing cdrtool[17062]: 1 CDRs, 1 normalized in 0 s @ 0 cps These are logs from cdrtool: 131225 17:43:35 527269 Query select * from prepaid where account = 'teddy(a)sip.test' 527269 Query select * from destinations where dest_id = '491525' and (reseller_id = 0 or reseller_id = 0) order by reseller_id desc limit 1 527269 Query select * from billing_customers where subscriber = 'teddy(a)sip.test' or domain = 'sip.test' or gateway = '10.57.85.221' or (subscriber = '' and domain = '' and gateway = '') order by subscriber desc, domain desc, gateway desc limit 1 527269 Query select * from billing_rates where name = 'bll_prepaid' and destination = '491525' and application = 'audio' 527269 Query update prepaid set active_sessions = '{\"WrNwobXRtxTIrP3YfZtbz8FmGRXJ6oh0\":{\"timestamp\":1387982615,\"duration\":36000,\"BillingPartyId\":\"teddy(a)sip.test\",\"MaxSessionTime\":36000,\"domain\":\"sip.test\",\"gateway\":\"10.57.85.221\",\"Destination\":\"+4915252136282\",\"DestinationId\":\"491525\",\"region\":null,\"connectCost\":\"0.0000\"}}', session_counter = '1' where account = 'teddy(a)sip.test' 131225 17:43:53 527269 Query select * from prepaid where account = 'teddy(a)sip.test' 131225 17:44:59 527269 Query select * from destinations where dest_id = '491525' and (reseller_id = 0 or reseller_id = 0) order by reseller_id desc limit 1 527269 Query select * from billing_customers where subscriber = 'teddy(a)sip.test' or domain = 'sip.test' or gateway = '10.57.85.221' or (subscriber = '' and domain = '' and gateway = '') order by subscriber desc, domain desc, gateway desc limit 1 527269 Query select * from billing_discounts where domain = 'sip.test' and application = 'audio' and destination = '491525' 527269 Query select * from billing_rates where name = 'bll_prepaid' and destination = '491525' and application = 'audio' 527269 Query select * from prepaid where account = 'teddy(a)sip.test' 527269 Query update prepaid set balance = balance - '660.0000', change_date = NOW(), active_sessions = '[]', session_counter = '0' where account = 'teddy(a)sip.test' 527269 Query insert into prepaid_history (username,domain,action,description,value,balance,date,session,duration,destination,reseller_id) values ('teddy','sip.blueline.mg','Debit balance','Session to +491525XXXXXXX for 66s','-660.0000','895739.9999',NOW(),'WrNwobXRtxTIrP3YfZtbz8FmGRXJ6oh0','66','+491525XXXXXXX',0) 1 when I telnet cdrtool on port 9024 from kamailio, I have the price, for the destination: ShowPrice From=sip:teddy@sip.test To=sip:00491525XXXXXXX@sip.test gateway=10.0.0.1 duration=247 2470.0000 Duration: 247 s App: audio Destination: 491525 Customer: domain=sip.test Connect: 0.0000 StartTime: 2013-12-26 10:50:07 -- Span: 1 Duration: 247 s ProfileId: bll_prepaid / weekday RateId: bll_prepaid / 0-24h Rate: 600.0000 / 60 s Price: 2,470.0000 I don't know why cdrtool sends mail to me and says that it doesn't find the destination, can someone help me please.

Almost done with another fruitful year, counting two major releases, the first edition of a dedicated conference for Kamailio and presence at over a dozen events world wide, it's time to say thanks to everyone that helped along the time -- developers, users, businesses investing resources and all the friends around the project! A Merry Christmas and great winter holidays! Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda
