[Users] Newbie needs some (transparent) proxy help
by ryadave＠gmail.com 24 Jan '07

24 Jan '07

Hi I've just had a project dumped on me to build a sip proxy to sit in front of our Nortel MCS setup (and ultimately other VoIP gateways). Previous admin was supposed to have done this but he recently been given the boot and hadn't even touched this project from what I can see. And I'm a VoIP newbie which doesn't help much - keen to learn but defo a newbie Setup is fairly straight forward from what I can tell but I seem to be doing something completely wrong so seeking help. New sip proxy (OpenSER) is to sit in front of the MCS (and in time other boxes as I mentioned) and it should proxy traffic to/from the sip servers based on the end users realms/domains (i.e. 1234(a)test1.sip goes to server X and 1234(a)tes2.sip goes to server Y) - I'll need to add an authentication layer here but one step at a time. There's no NAT'ing or anything else going on - everything (clients, sip server & sip proxy) sits on public IP space. All I've been able to get to work so far is registration but can't make or receive calls. I've spend 2 days now trying to figure this out (newbie eh ?) and am under increading pressure from management to get this sorted so am getting desperate. I've googled this to death and tried all the various configs that sounded like they would do the job - but none have. I'm sure someone has already done this and would appreciate if you could share the config with me ? thanks dave

[Serusers] Info about my iptel.org blog
by Greger V. Teigre 24 Jan '07

24 Jan '07

Hi, As some of you might have seen (there's a link on the http://iptel.org/ main page), I keep a blog covering iptel.org related things. I comment on threads of particular on serusers and serdev, as well as report on status and my thoughts around iptel.org projects, up to now with a focus on SER and the upcoming new release. http://sipstuff.blogspot.com/ The intention is to improve communication about what is happening on iptel.org, as well as covering things of interest that is maybe not suited for the mailing lists or as a page on iptel.org. However, the posts and opinions are entirely mine and are by no means official attitudes or opinions of iptel.org. ;-) I encourage comments (comments are allowed in the blog), suggestions, discussions on the mailing lists, or private notes related to what I cover in the blog! Cheers, Greger aka g-)

[Users] TLS between Openser and UAs
by Jayesh Nambiar 23 Jan '07

23 Jan '07

Hi, I am trying to implement Openser with TLS. But my requirement is as follows: I wanted that all the UAs that register to my Openser Server should come through TLS and when I forward that call to my PSTN gateway it should go through UDP. While forwarding I understand that it can be done using t_relay_to_udp() but how can the first part be achieved. I needed that all the registrations and subsequent messages between Openser and UAs be in TLS. Is this possible, and if yes what all certificates will be required on my server side and the UA side? The documents only mention about TLS transport between servers/proxies. Please someone help me as I am new to TLS and my understanding related to TLS is not that good. Thanks, w/regards, Jayesh __________________________________________________________ Yahoo! India Answers: Share what you know. Learn something new http://in.answers.yahoo.com/

[Users] Routing inbound calls
by Bill Neely 23 Jan '07

23 Jan '07

We are trying to route inbound calls with openser. In other words, I would like calls from DID 123-345-1234 to go to extension 123 and calls from DID 234-456-6789 to go to extension 234. I assume that lookup("aliases") is the way to do this. But I need an example of what would be in the aliases database. Any example would help. TIA. Bill -- 702-874-3833 1-866-553-3833

[Users] Please Advice!!
by Jayesh Nambiar 23 Jan '07

23 Jan '07

Hi, We are planning to use Openser in a large scale deployment. We are planning to stick to Linksys ATAs and IP Phones. Now all these phones have good NAT handling capablities. I just wanted to understand if it is better to handle these parameters on the UA side instead of Openser side. Will it cause some overhead to reduce at the Openser side. By using these UAs is it also possible to eliminate the use of Mediaproxy/RTPproxy at the Server side. I have the Openser working fine with Mediaproxy but I just wanted some expert suggestion from the people who are using these kind of UAs. Thanks, w/regards, Jayesh. __________________________________________________________ Yahoo! India Answers: Share what you know. Learn something new http://in.answers.yahoo.com/

[Users] Support for T.38
by Max Gregorian 23 Jan '07

23 Jan '07

Hi, Does anyone know if OpenSER supports T.38 for Fax over IP? Or has anyone managed to get it to work? I did some quick tests and what I got was the destination Fax machine rang, but the fax message did not arrive. I don't think the destination fax picked up. Setup was: Fax (PC modem) -> IP Gateway -> OpenSER -> PSTN -> Fax machine Is it possible the Fax tones are not being properly generated by OpenSER, and so not being recognised by the Fax machine? (For reference, the Gateway used is advertised as supporting T.38)

[Users] About the realm
by Howard Tang 22 Jan '07

22 Jan '07

Hi, I have (silly) question about the realm for authenication which I am not able to fix it. Currently, i have the following config. if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("1.1.1.1", "subscriber")) { www_challenge("1.1.1.1", "0"); exit; }; if (!check_to()) { sl_send_reply("401", "Unauthorized"); exit; }; consume_credentials(); save("location"); exit; }; if (method=="INVITE") { if (!proxy_authorize("1.1.1.1","subscriber")) { proxy_challenge("1.1.1.1","0"); exit; } if (!check_from()&& !does_uri_exist()) { sl_send_reply("403", "Use From=ID"); exit; } consume_credentials(); }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); }; My problem is user can only register or make phone call using 1.1.1.1 as a domain. I have setup a domain name on this ip address. for example sip.proxy.com. when i set up sip.proxy.com as the domain/proxy address in the UA, i was not able to register and received a 503 service unavailable. What do i need to do to allow user register using ip address or the host/domain name at the same time? currently i have it working for ip address only. In the subscriber tables-domain column, i have ip address for the users, do i need to add another entry with the domain name in the domain column instead of he ip address? if that is the case, i will have 2 username which the same number in the table. Please help. -- Howard Tang
