[Serusers] NOTIFY and WATCHERINFO_NOTIFY
by Alois Schafferhofer 21 Jun '06

21 Jun '06

Hi, I have some questions about PUBLISH handling. SER sends a lot of NOTIFYS when status changes. Additionally, SER sends more than one tuples in one Response (open and closed in one Response). The second question is about WATCHERINFO_NOTIFY. I have the line: modparam("pa", "watcherinfo_notify", 1) in my config file, but SER doesn't NOTIFY me, if someone SUBSCRIBEs to my Presence information.

[Serusers] Sending NOTIFY messages from presence module to an SIP Proxy Server
by Anton Schula 21 Jun '06

21 Jun '06

Hello, I have a routing problem with SER and OpenSer regarding presence NOTIFY messages. I want to use OpenSer (OSER in the diagram below) as SIP registrar and for routing SIP messages (which is working perfectly). And I have a separate SER with the PA and RLS modules (called SER-PA_RLS). This one also works perfectly when used as standalone server. Now I have configured the OSER to forward PUBLISH and SUBSCRIBE messages to the SER-PA_RLS. This part is O.K., messages are routed from the client over the OSER to SER-PA_RLS, reply messages travel back from SER-PA_RLS to the OSER and from there to the client. That's O.K., so OSER apears to have correct routing. But NOTIFY messages originating at the SER-PA_RLS are sent directly to the client, using the clients contact address. How can I configure SER-PA_RLS to send the NOTIFY messages via the OSER? In fact, this is all that SER-PA_RLS shall send to the outside world. All routing decissions shall be done in the OSER. The SER-PA_RLS should not be directly accessed (a firewall is in place). Call Flows: =========== Messages from Client to Presence server are O.K. OSER routes them to the SER-PA_RLS. Responses travel back via OSER. ###### ######## ############## # UA # # OSER # # SER-PA_RLS # ###### ######## ############## | | | |----PUBLISH--->| | | |----PUBLISH---->| | |<-----OK------- | |<------OK------| | | | | | | | |---SUBSCRIBE-->| | | |---SUBSCRIBE--->| | |<-----OK------- | |<------OK------| | | | | | | | | | | Intended route of NOTIFY messages: ###### ######## ############## # UA # # OSER # # SER-PA_RLS # ###### ######## ############## | | | | |<----NOTIFY-----| |<----NOTIFY----| | |-------OK----->| | | |-------OK------>| | | | | | | Observed route of NOTIFY messages: ###### ######## ############## # UA # # OSER # # SER-PA_RLS # ###### ######## ############## | | | | | | |<-------------NOTIFY------------| |----------------OK------------->| | | | | | | (In fact I only see the UDP SIP NOTIFY leavin the SER-PA_RLS machine. The firewall blocks this message, so the client nevers receives it.) I tried several configurations in ser.cfg, including ... if (method=="NOTIFY") { log(1,"NOTIFY forwarded to OSER\n"); forward(OSER-hostname,5060); } ... I never saw the log message. I think, that sending out messages from the SER or at least the presence module is independend from routing in the ser.cfg. Can anybody tell me how to forward all outgoing messages to the OSER? Many thank's in advance! best regards A. Schula PS: For your information On OSER, I simply use this if (method=="SUBSCRIBE" and src_ip!=SER-PA_RLS_IP || method=="NOTIFY" and src_ip!=SER-PA_RLS_IP || method=="PUBLISH" and src_ip!=SER-PA_RLS_IP) { forward_udp(SER-PA_RLS_IP,5060); exit; }; -- Echte DSL-Flatrate dauerhaft für 0,- Euro*!

Hi, I would recommend any of the following for the aforesaid: 1. Cisco media gateway (Router can be converted to a media gateway using voice interface cards). We use Cisco 2600 and 7200 (with MPLS support) series for this functionality. 2. NMS media gateway Some other market leading products are also available for this purpose, for example products from Lucent, Alcatel, etc. Regards, Benjamin. -----Original Message----- From: serusers-bounces(a)lists.iptel.org [mailto:serusers-bounces@lists.iptel.org] On Behalf Of Nick Hoffman Sent: Wednesday, June 21, 2006 5:54 AM To: serusers(a)lists.iptel.org Cc: George, Benjamin Subject: Re: [Serusers] How to start a VOIP business ?

Hi, I too can provide you some inputs on this apart from the things which are already mentioned: 1. You may require a media server for playing prompts, announcements, etc 2. Voice mail server to store and play back voice mails 3. Signaling + Media Gateway if you want to connect to PSTN world 4. Any good performance management/monitoring tool (normally part of OSS) to measure and manage the performance of the entire infrastructure to assure zero/minimum downtime Regards, Benjamin. _____ From: Greger V.

It's a fairly big questions you're asking. But basically you're onto it ;-) Ad 1. You should go for something newer than 9.0 Ad 2. You need to decide on your maintenance schedule and policies for upgrades/patching etc. Many larger-scale deployments are based on SER 0.9.x because a) it has proven extremely stable b) it is currently maintained for bug and security fixes and will be for a while. Others choose openser to get more features, but you need to make sure that you can handle testing and deployment of new versions more often. Ad 3. You need a RADIUS server with a user database or you can use mysql (you need mysql regardless of using RADIUS or not) g-) Concy Pereira wrote: Sir, I would like to know how can start a successful SIP base VOIP business.

[Users] Final ACK getting wrong IP address
by Justin Pearce 20 Jun '06

20 Jun '06

Hey guys, I apologize for the length of this message, but I am experiencing a frustrating problem. Let me first explain the situation: We have a custom video conference app installed on two separate computers within our network. We have our OpenSER server setup with a public address at our ISP. There is a NAT between the clients and the OpenSER server with both clients behind the same NAT. Both clients have port ranges mapped through the firewall to allow for audio and video. We were having some issues previously with the clients unable to initiate calls between one another through the server, however I did some work with the config file and managed to get it working. While I was out of town, the problems came back even though the config had not been changed. The issue that now seems to be the problem is that the call process seems to happen properly up to the point at which the client making the call acknowledges the ACK from the client being called. The acknowledgement of the ACK seems to be getting sent to the private IP address as opposed to the public address as all the other communications seem to be. I am not entirely certain where I have the problem, if it is with the server (easier fix) or with the actual clients (difficult fix). I have appended an excerpt of the packet capture (from Ethereal) from the point at which the client programs through the complete call process (without the unregister, since that would seem to be redundant). I have also appended my config file. Would someone be able to look at this and tell me where I screwed up (aside from inside my own head)?

[Serusers] I must be stupid... but

hi all, I have modparam("tm", "fr_inv_timer", 60) when a callee doesn't anwer, he often send a 487 (cancelled) before 60 seconds... It means timeout in fact or no answer... If the caller stop the call, I also get a 487... How to make the difference on a 487 generated by the caller and by the callee? It makes difference, if it's generated by the callee, I will forward the call to voicemail or another number, if it's generated by the caller, I will do nothing. When I set fr_inv_timer to 15, I always get a timeout and it's ok, but my customers dislikes that as well as the callees who needs to be better than Ben Jonhson for the 100meters :( Does exists a parameter to be send to the callee to tell him to wait 60 seconds + 1 before sending me a Cancel? Regards, Olivier
