[OpenSER-Users] Usrloc lookup ad parallel forking
by Edoardo Serra 15 Oct '07

15 Oct '07

Hi all, I have OpenSER (1.2.2) acting as registrar server. If the same user hase more than one AOR I'd like to do parallel forking and send the INVITE to every contact I have for that user. At the moment my configuration file looks like: if (!lookup("location")) { sl_send_reply("404", "Not Found"); exit; }; t_on_reply("1"); if (!t_relay()) { sl_reply_error(); }; exit; but it rely only to the AOR with the highest q value It should be a common situation but I cannot find any doc about it. Tnx in advance Regards Edoardo Serra

[OpenSER-Users] append_rpid_hf without authentication?
by Alex Massover 14 Oct '07

14 Oct '07

Hi! I want to add rpid before sending the INVITE to the gateway, because the gateway requires it, but the problem is that clients don't send REGISTER and I don't use any authentication (like www_authorize). Probably because of that my 'subscriber' table is empty all the time. Can I still use somehow append_rpid_hf() or I need to try to build it with append_hf() manually? BR, Alex.

[OpenSER-Users] UAC module parameters
by CB 14 Oct '07

14 Oct '07

I am trying to understand the relationship between the various module parameters for the uac module. Imagine I want to authenticate on a proxy user different credentials in different situations. The credential module parameter allows specification of the username, realm and password. I think (correct me if I'm wrong) that I can have multiple of these specified for various realms: modparam("uac","credential","user1:realm1:pw1") modparam("uac","credential","user2:realm2:pw2") According to the documentation, "This parameter is required if UAC authentication is used." What then is the purpose of the auth_realm_avp, auth_username_avp and auth_password_avp module parameters? Do they replace the credential parameter or are they for something different? Any help appreciated. Regards Cameron

[Serusers] uri contains no digits, only an IP
by Stephen Helfen 12 Oct '07

12 Oct '07

How am I supposed to route these? Essentially, I get an INVITE from an end-user. The uri is simply sip:XXX.XXX.XXX.XXX What is currently happening is that the IP address represented by Xs above is the IP of my proxy. The proxy sees this URI and forwards the call back to itself. This is obviously wrong, but I am not sure how to correct it. The routing data I need is in the to_uri, but I am not sure how to place this into the uri field. rewriteuri does not work on variables, only strings. How can I accomplish this? Currently on version 0.9.6. Thanks in advance, Steve _________________________________________________________________ Climb to the top of the charts!

[OpenSER-Users] AVPs and PostgreSQL data types.
by Alex Balashov 12 Oct '07

12 Oct '07

Greetings, I have a problem passing AVPs to stored procedures (or in other SQL contexts) that require an integer argument. It is not a show-stopper, it just throws a warning: 0(6535) PG[get_columns]: Unhandled data type column (my_stored_proc) OID (869), defaulting to STRING This results from something like: avp_db_query("SELECT my_stored_proc($avp(S:my_avp))"); Now, $avp(S:my_avp) is a numerical value, so it does end up working. However, because AVPs are not natively "typed" as numerical or string values in a way that is represented at the Postgres layer of the avpops implementation, evidently, this situation arises. Is there any way to fix this? I have tried using CAST() in the SQL statement, but that did not appear to help.

by Angela Gao 12 Oct '07

Hello, all, I have one question, if in ser.cfg, loadmodule "/home/linus/gao/usr/local/lib/ser/modules/mysql.so", does it means we must go to mysql website and download and install it? and then create db with name config in ser.cfg ? I got some error when start ser. 0(13676) ERROR: load_module: could not open module </home/linus/gao/usr/local/lib/ser/modules/mysql.so>: libmysqlclient.so.14: cannot open shared object file: No such file or directory 0(13676) parse error (81,13-14): failed to load module Thanks for any suggestion. -- Best regard, Angela

Re: Re: [OpenSER-Users] CPL extension
by Daniel 12 Oct '07

12 Oct '07

Hi Bogdan, I don't want to change CPL's standard element specified by RFC, but only add a new type of switch. But Internal parser and Interpreter are included within CPL-C Module of OpenSER, right? So, I have to say to OpenSER how it parses and manages this new element. Regards, Daniel Bogdan-Andrei Iancu wrote: Hi Daniel, CPL is specified by an IETF RFC, so changing it will break compatibility. anyhow, it is not sufficient to change the DTD - you need to change the internal parser (that converts the XML to a binary, easy to run format) and also the interpretor itself (using the binary format). regards, bogdan Daniel wrote: Hi All, I'd like to extend CPL functionality adding a new switch element.
