[Serusers] What is the meaning of "Noisy Feedback"?
by JamesGemini 13 Aug '05

13 Aug '05

Does the message "Noisy Feedback tells" mean that the server is configured to include debugging information in its communications? Kind of like "verbose" mode?

Re: [Serusers] Distributing "OSP enable SER" binary file w/ source

Hi Jan, This sounds good. I have another question: How do you deal with dependencies on external libraries. Do you store the libraries in CVS? For the OSP module, the toolkit library is required, and I am wondering what is the best way of providing it to the users. Also, does IPTell or anyone else distribute pre-compiled versions of SER? I am trying to explore the possiblities of distributing a OSP enabled version of SER for those who dont want to go through the trouble of compiling the OSP library. Vikrant

In fact I expect to use asterisk 1.2 for all telephony features IM/presence, ... I would just setup up ser + rtp proxy for far end nat and proxying . I agree you now when you say "i dropped sems along time ago cause asterisk is better." which damage sems+ser+serweb don't provide a good open source telephony project. My I call you via sip if possible send me you address out of list. regards harry --- Iqbal <iqbal(a)gigo.co.uk> a écrit : > if u want some help with asterisk let me know, it > failry simple to get > work with ser, i dropped sems along time ago cause > asterisk is better. > Have voicemail and pbx, what u want to watch out for > is how you are > grouping callers etc, what I do is all users > (corporates ) who need > features of asterisk get an entry in grp table in > ser, which says > corporate, only these calls goto asterisk, the rest > stay in ser, which > saves overhead, cause asterisk does slow things > down. > > Iqbal > > harry gaillac wrote: > > >Hello, > > > >Thanks I think I 'll do it myself when asterisk 1.2 > >will be available i will set up it like most of > people > >instead of sems. > > > >A few people are interested in sems . > > > >I' ll use asterisk as sip media server ser as proxy > >and rtpproxy (far end nat) . > > > >Regards > >Harry > > ___________________________________________________________________________ Appel audio GRATUIT partout dans le monde avec le nouveau Yahoo!

Re: [Serusers] Distributing "OSP enable SER" binary file w/ source code
by vmathur＠transnexus.com 12 Aug '05

12 Aug '05

Hi Jan, The code has been written as a SER module. The details of the code are available at: http://developer.berlios.de/projects/osp-module Right now the process of compilation requires that you download the OSP toolkit source code and complie it. This would build the OSP client library that the SER would use. You should then download the SER and the OSP modules and build them. The process is rather lengthy and we were wondering if we come up with an easier way of doing this. What exactly is the experimental branch in CVS ? Thanks, Vikrant --------------------------------------------------------------------------------------------------- In what form does the come come ? Did you implement it as a SER module ? If so then we can put it in the experimental branch in CVS. If you made some changes to other modules or the core then it would be great if you could generate patches against the latest development version. Jan.

Re: [Serusers] Distributing "OSP enable SER" binary file w/ source code

Sure Juan, I am currently working on a document that details how to compile OSP with SER, and also a white paper which tells you about the benefits of using OSP with SER. It should be ready soon :) and will send it across. In the meantime if you want to learn more about OSP, you can go to www.transnexus.com. By the way, we have also recently implemented OSP for use with the Asterisk PBX. So, if anyone here wants to use OSP for routing, security, or billing with Asterisk, let me know and I can provide more details. Thanks, Vikrant ---------------------------------------------------------------------- Hi Vikrant. It seems very interesting to me. I would like you to send me the info you have. Regards Juan ------------------------------------------------------------ From: serusers-bounces(a)iptel.org [mailto:serusers-bounces@lists.iptel.org] On Behalf Of vmathur(a)transnexus.com Sent: Friday, August 12, 2005 11:00 AM To: hernan_gomez_1(a)yahoo.com Cc: serusers(a)lists.iptel.org Subject: Re: [Serusers] Distributing "OSP enable SER" binary file w/ source code Hernan, OSP uses Public key based authentication and encrytion schemes, which are stronger than Radius's shared secrets. If you use OSP for authentication and authorization, you need not use Radius. OSP, just like Radius, has a client stack, which is implemented in the SER, and has a Server, which provides centralized call routing, accounting, and security. At the time of startup, the OSP server and the client, the SER in this case, exchange their public keys. The public and private keys can then be used to encode/decode messages as desired. A typical call setup procedure looks like this 1. The source SER goes to the osp server to get the SIP URI corresopnding to the destination. The message is encoded using the source SER's private key. 2. The osp server decodes the message using source SERs public key and after successful decoding (authentication) returns the route back to the source. Along with the route, it also sends back a digitally signed (using the OSP Servers private key) token. 3. The Source uses the route returned by the OSP Srver to send an INVITE. The INVITE message contains the token issued by the OSP Server 4. The destination decodes/validates the token using the OSP Servers public key. Upon successful validation (authorization) it accepts the call. This saves you the effort of mantaining cumbersome access lists for authentication. I can provide you with more documentatin on OSP and how to use SER with OSP if you wish Thanks, Vikrant ------------------------------------------------------------------------------------------------------------- Fogive my ignorance for I have never heard of OSP before ;) You mentioned Radius in your message. How does Radius authentication work in OSP? I am having a tough time getting mine to work. hernan vmathur(a)transnexus.com wrote: Dear All, I have recently implemented OSP w/ SER. OSP is an ETSI defined protocol, which I am using for ceneralised routing, and security of my inter-domain calls. The problem, however, is that the build process is a little lengthy. I want to contribute my implementation to this group so that anyone who is struggling with SER routing configurations or Radius authentication issues may benefit from it. I was, thus, wondering if we can have a binary file of the OSP enabled SER, that can be distributed with the source code. Does anyone have an opinion on this? Also, for anyone who wants to check-out this implementation, I can provide more details. Thanks, Vikrant

[Serusers] Users authentication scheme
by Federico Giannici 12 Aug '05

12 Aug '05

I'm relatively new to SIP and I'm learning how to configure SER for a little ISP. I'm currently asking myself when we should authenticate users. Obviously, I don't wont to have an open-relay SIP server. So I'm thinking that I have to authenticate users for every message that comes and that have a "From:" header that matches one of our domains. Is this correct? Then I have to call check_to() for REGISTER messages and check_from() for all the others. Is this correct? So here it is a scheme of the logic I'm going to implement. Do you think is correct? IF uri == myself IF method == REGISTER www_authenticate() check_to() save() ELSE IF From == myself proxy_authenticate() check_from() Normal processing ELSE IF From == myself proxy_authenticate() check_from() t_relay() ELSE Error! Thanks. -- ___________________________________________________ __ |- giannici(a)neomedia.it |ederico Giannici http://www.neomedia.it ___________________________________________________
