by Fernando Rodriguez

Hello, Is there a place were i can read about avpops module regarding src and dst ip this is for using mediaproxy when the users are in diferent interfaces of the equipment or diferent networks so i can only mediaproxy the ones that need this functionalyty and the ones on the same network connect direct from one to the other. Thanks a lot Fernando Rodriguez V.

[Users] multiple aliases

by Mike Williams

Is it possible to use aliases to route to multiple sip uri's?I would like to have one user resolve to say, three different users from the database. Also, I assume I can alias a local sip address to a user in another domain / at another server? I want to have a virtual number that rings three seperate phones when called, regardless of whether they are sip or pstn. Ideally, I would be able to do this with aliases. Thanks for any help.

[Users] openser with radius problem

by Jayesh Nambiar

hi all, I tried compiling openser with radius support. everything was fine. I did it according to radius howto mentioned in the iptel.org. The test for authentication was also ok. but when i try to start the openserctl, I get the following error in log: load_module: could not open module </usr/local/lib/openser/modules/acc.so>: libradiusclient-ng.so.2: cannot open shared object file: No such file or directory I googled old mailing list and found out that the LD_LIBRARY_PATH needs to be set. But i have no idea how and where to set this. can somebody pls help me understand this problem. thanx in advance jayesh Send instant messages to your online friends http://in.messenger.yahoo.com

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

by vmathur＠transnexus.com

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.

[Users] UAC

by Kapil Dhawan

Hi List I am using Cisco 2600 to send calls to OpenSER but 2600 is not sending the username in from field, so i used UAC module. Issues. 1. I need to make changes in openser.cfg and restart service, do we have any other alternative. 2. My calls are getting disconnected after a random time interval say couple of minutes.

[Users] Context of flags - flag visibility - in openser

by Joachim Fabini

Hi, Again a question regarding the OpenSER documentation, specifically the usage of flags: What is the context and visibility scope of flags in openser? What is their lifetime? Maybe some piece of code to clarify things: route { if (method=="REGISTER") { setflag(10); # do some processing } if ((method=="INVITE")||(method=="BYE")) { setflag(11); } # do some more processing t_relay(); } onreply_route() { if (isflagset(10)) { # received a reply on register, process it } if (isflagset(11)) { # reply on invite or bye } } a) Can we expect the flags 10/11 to be identical for route and onreply_route - i.e. in the example above, are the flags in status "set" when processing the onreply_route? I.e. isflagset(10) returns true if we process the 200 OK in reply to a REGISTER? b) Do we need to explicitely reset the flag or is it automatically cleared? Specifically: If an INVITE and the matching OK are processed, is it required to reset the flag afterwards in onreply_route? I.e., if after the 200OK to INVITE a 200 OK reply to a SUBSCRIBE is processed by onreply_route and we did _not_ reset the flag 11, does isflagset(11) return true or false on the 200 OK for SUBSCRIBE? Finally another question: must onreply_route be explicitely triggered (like for onreply_route[1] using t_on_reply("1")) or is the default onreply_route anyhow executed automatically on any stateful reply? Thanks in advance, --Joachim
