RTPPorxy -> RTPEngine migration issue
by Arsen Hovhanissian 10 Jan '16

10 Jan '16

Hi everyone, i’ve been having this “not so problem” going on. So I have rtpengine installed on a server and use the default rtpproxy module on kamailio and it works beautifully. Having read the rtpengine modules description, I see that it is a drop in replacement of rtpproxy. So I keep trying to update the module names and function names but it keeps giving me this message when I start up kamailio. ERROR: rtpengine [rtpengine.c:1622]: rtpp_test(): proxy responded with invalid response Software versions: Kamailio: 4.3.4 RTPEngine: 4.1.1 Any ideas on what it could be?

Kamailio - Asterisk: Handling loss of SIP BYE and dangling channels
by Benjamin Fitzgerald 08 Jan '16

08 Jan '16

Hi, I'm wondering what the best approach to handling a SIP dialog when one endpoint disappears/fails to send the BYE message. I have Kamailio as a proxy for all mobile (iPhone/Android) SIP clients. Occasionally, the user hangs up the call but no BYE message is received. This means that Asterisk has an open channel even though there is no client. Kamailio also continues to receive successful registrations from the SIP client so the endpoint is not down completely. Is Kamailio the appropriate place to handle this situation? What do you recommend? If not could you point me in the right direction? RTP timeout? Asterisk? The SIP client itself? Thanks for your help.

Audio issue when using 2 port ATA
by Daniel W. Graham 08 Jan '16

08 Jan '16

Setup is - 2 port ATA <> FIREWALL <> KAMAILIO / RTPPROXY <> ASTERISK If I have a single port in use behind the firewall, all NAT functions work properly and media is relayed through rtpproxy. If I have both ports in use behind the firewall, when outbound calls from UA are placed there is two way audio on both calls. However if inbound calls are placed to UA, the first call works, second call only has outbound audio. Different SIP URI is used for each port. If the firewall is eliminated everything works fine. Anyone have an idea how to troubleshoot or what could be missing? I have done packet captures on both the UA side and Kamailio side, and I see two RTP flows (rtp ports match on both sides as well) despite lack of inbound audio on the second call. If I can post anything config wise that would help let me know. Thanks! -Dan

Example kamailio.cfg t_check_trans()
by Phil Lavin 08 Jan '16

08 Jan '16

Hi there, The example config that Kamailio ships with contains this block of code in request_route: # handle retransmissions if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); I am not fully understanding the requirement for either of the t_check_trans() here. As far as I can see from the documentation, t_check_trans() returns a boolean value and does not modify any data internally. Can anyone help me find out what the relevance of the t_check_trans() calls is?

using pipelimit at CPS (1 second)
by Vik Killa 08 Jan '16

08 Jan '16

Hello, has anyone used pipelimit at a timer_interval of 1 second? We would like to do rate-limiting based on CPS? The doc says it can be CPU intensive. Testing with SIPP, we see the CPU go up to around 30% at 500 CPS (with pipelimit blocking at 300 CPS) Thanks /V

Add Record-Route on 200 OK
by Igor Potjevlesch 08 Jan '16

08 Jan '16

Hello, I'm looking for a way to add a Record-Route into a 200 OK before relaying the message to the UA. Indeed, I'm facing an issue where the 200 OK is relayed to the UA without Record-Route and with an IP address into the Contact header. So, the UA sends back his ACK to the Contact instead of the proxy itself. Is it possible to achieve this? Regards, Igor.

Negative value returned when using sql_pvquery
by Jonathan Hunter 06 Jan '16

06 Jan '16

Hi Guys, Wonder if anyone has experienced this before, on kamailio 4.1. I am using an sql_pvquery and it works fine, unless I pull a value from the database that is defined as 10 digits and starts with a 3, actually its populated as 03785702370 but due to the table it removes the leading 0 (bigint(20) unsigned). Running a manual query in my database for a DestinationMsisdn I get; select DestinationMsisdn,SourceMsisdn from MsisdnPoolAllocations where PoolMsisdn='+44162489xxxx';+-------------------+--------------+| DestinationMsisdn | SourceMsisdn |+-------------------+--------------+| 3785702370 | 4474526xxxxx |+-------------------+--------------+ However running in the kamailio.cfg an sql_pvquery to do the same query as below; sql_pvquery("cd","select DestinationMsisdn,SourceMsisdn from MsisdnPoolAllocations where PoolMsisdn='$rU'","$var(MOdest),$var(NewSourceMSISDN)"); However this returns a value of -509264926 for $var(MOdest) which should just be the 3785702370 number. What can cause kamailio to interpret this as a negative value? Has anyone seen this before? Many thanks Jon

Thanks for reply. I check one more time, and does not see any non SIP (HEP) packets received on port 5060 of kamailio. May bee parser trying to parse (HEP) packet when it going out via socket to capture server? When I turn of topoh module I does not see any errors in log.

Is it possible to use kamailio as a Webrtc gateway and integrate it into to a conference bridge for handling webrtc clients in conference bridge?
by suganthi karthick 05 Jan '16

05 Jan '16

Hi all, I need to implement a WebRTC gateway for an existing conference bridge. The WebRTC gateway has to support Signaling, ICE and DTLS. The webrtc clients can be JsSIP or any webrtc client. The conference bridge is an existing working one for SIP clients, and I am trying to add webrtc support for that. The webrtc gateway needs to be implemented in a way like a library because it needs to be integrated into the existing platform. There are some init functions and config function from the existing conference platform, based on which the webrtc gateway has to be configured. Also, when a webrtc call come from a webrtc client, it needs to handle the signaling and the media(RTP) has to go to the conference bridge platform. It would be really helpful if you suggest whether I can use openSIPS for this purpose and use it as a library and integrate into the exiting platform? Your suggestions will be more helpful. Thanks.

But there is always prompts like following in rtpengine’s log: Dec 22 19:57:52 localhost rtpengine[12679]: [oaNEqGokmqgaXzj0xWyPeJDGPX7ln0gG port 30136] Too many packets in UDP receive queue (more than 50), aborting loop. Dropped packets possible Dec 22 19:57:52 localhost rtpengine[12679]: [oaNEqGokmqgaXzj0xWyPeJDGPX7ln0gG port 30156] Too many packets in UDP receive queue (more than 50), aborting loop. Dropped packets possible Dec 22 19:57:52 localhost rtpengine[12679]: [oaNEqGokmqgaXzj0xWyPeJDGPX7ln0gG port 30156] Too many packets in UDP receive queue (more than 50), aborting loop. Dropped packets possible So I am wondering whether this prompt is normal. Otherwise, what should I do to prevent this to happen? Thx a lot! ------------------------------------ 北京邮电大学网络技术研究院网络与交换技术国家重点实验室田军 +86 18810315790 mozillafire(a)bupt.edu.cn ------------------------------------

Re: [SR-Users] Presence - Subscription based NOTIFY to enable MWI

Alright I guess this is one of those duhh… moments, all this time I was forgetting to add the content length to the NOTIFY event. Remark: DO NOT FORGET the content length! Thanks for the help, very much appreciated!

I see, what i’m trying to do is actually to limit querying the DB by updating the MWI only when there is activity. In other words to send a NOTIFY when the user receives a new message in his voicemailbox. I am not sure if it’s possible to send the NOTIFY for example 5-30 mins after the initial subscribe.

Presence - Subscription based NOTIFY to enable MWI
by Arsen Hovhanissian 03 Jan '16

Hi everyone, I’m trying to send a NOTIFY event using “sipsak” to enable the MWI I read up a lot of documentation and didn’t really find the information needed to accomplish this. So I have: Phone 1 -> P1 Server 1 -> S1 (Kamailio 4.3.4) Server 2 -> S2 (sipsak) P1 registers to S1 and creates a new entry in the active watchers table with a "message-summary” event. At this point I am assuming that any request I would send will be out of dialog. Now the question is, How could I reply to that SUBSCRIPTION with a NOTIFY? Thanks in advance!

tsilo and linphone android connected via TCP
by Vasiliy Ganchev 29 Dec '15

Hi folk! sorry for first sending to the wrong list ! Currently playing around with push notification in kamailio, have a bad case. Would appreciate any idea. Scenario (all devices connected via TCP): UA-A - sipphone, UA-B[1] - sipphone UA-B[2] - Linphone android Server - kamailio+asterisk UA-A call UA-B (UA-B[1] - online, UA-B[2] - offline) Kamailio make ts_store, and t_relay to UA-B[1], for UA-B[2] kamailio send push notification UA-B[2] appear registered, I make ts_append, and see kamailio sending INVITE to UA-B[2], but tansport used is UDP (expected TCP) If I use UDP on UA-B[2] - have no issue. I am using kamailio-4.2.5, looked in sources of current master, did not found changes that could help in my scenario. General question - does anyone has same problem using ts_append for TCP connected devices? If TCP in ts_append should work OK, any other idea? cheers! -- View this message in context: http://sip-router.1086192.n5.nabble.com/tsilo-and-linphone-android-connecte… Sent from the Users mailing list archive at Nabble.com.
