[Serusers] http tunneling
by Imran Akbar 10 Dec '05

10 Dec '05

Hi, I've tried to use a softphone from behind a corporate firewall which only allows http requests through its proxy - and it doesn't work, even with STUN. I've heard that tunneling through HTTP would allow VoIP to work in this situation - does anyone know how to set this up, with SER or other hardware/software? Thanks, Imran

[Serusers] SER + SEMS & Music on Hold
by Waldo Rubinstein 09 Dec '05

09 Dec '05

Does anyone have any configuration sample on setting up SER + SEMS in order to "put a call on hold and listen to MoH" while SER reaches the destination peer(s)? Or at least point to some documentation referencing this? Thanks, Waldo

[Serusers] announcement: student project finished: partiSIPation
by Juha Heinanen 09 Dec '05

matthias, i looked at partiSIPpation documentation and didn't quite understand why microphone and speaker volumes are part of the api. i would think that those are internal matters of the gui component. when gui places a call, i would imagine it gives to core an ip address and port that it wants to use for the media plus a list of codecs it supports. i don't understand what volume issue have to do with communication between gui and core. -- juha

Hi, to get multi-leg accounting to work, is it necessary to avp_write "something" to the src_leg_avp_id/dst_leg_avp_id avp's? Right now I only get "n/a" in those columns. I've tried to use avp_write without any success. br, hw -- Helge Waastad Senior Engineer Systemavdelingen Smartnet

[Users] RE: [Devel] unixODBC Database Connection Problem
by Lenir 09 Dec '05

Ok, I tried using the FreeTDS driver for unixodbc and I got a more detailed error message that might shine a light: Failed to connect The driver reported the following diagnostics whilst running SQLDriverConnect IM007:1:0:[unixODBC][FreeTDS][SQL Server]Could not find UID parameter HYC00:2:0:[unixODBC][FreeTDS][SQL Server]Driver not capable 0(0) auth_db:str_fixup: Unable to open database connection 0(0) ERROR: fix_expr : fix_actions error ERROR: error -1 while trying to fix configuration These are my entries in /etc/odbc.ini [SYBASE] Driver = /usr/local/lib/libtdsodbc.so Description = Sybase Server Trace = Yes Trafcefile = /tmp/odbc.log #Servername = JDBC Server = xx.xx.xx.xx Port = 5000 DSN = database Database = database #UserID = username # I tried using both UID and UserID, had same results UID = username Password = passwd TDS_Version = 5 These are my entries in /etc/freetds.conf: [SYBASE] host = xx.xx.xx.xx port = 5000 tds version = 5 For whatever reason the module is not picking up the UID and PWD from the db_url parameter i.e. modparam("usrloc|auth_db", "db_url", "unixodbc://username:passwd@xx.xx.xx.xx/SYBASE") The way I fixed the problem was by changing the file my_con.c, line 69: From: sprintf( stringDNS, "%s%s%s", "DSN=", id->database, ";"); to: sprintf( stringDNS, "%s%s%s", "DSN=", id->database, ";UID=username;PWD=passwd;"); And now works fine. Also, to add debug to figure out which SQL queries fail, I changed the file dbase.c line 75: From: LOG(L_ERR, "Return value: %d\n", ret); To: LOG(L_ERR, "Return value: %d, Performing query: %s\n", ret, _s); Now everytime a query fails it'll say the result msg, as well as the actual query that failed.

[Users] Relaying and failure route - misrouted ACK
by Stefan Prelle 09 Dec '05

09 Dec '05

Hi folks, I need an advice regarding failure routes. I want the (Open)SER to route all incoming calls to a PSTN gateway. If that route fails (e.g. because the gateway is down) it shall route the calls to another gateway. I managed to archieve that in the failure case the second gateway receives the call. But the ACK request that the caller sends when receiving the 200 OK is delivered to the primary target again, not to the fallback gateway. My configuration (excerpt): route { ... record_route(); if (loose_route()) { t_relay(); exit; }; t_on_failure("1"); t_relay_udp("192.168.0.37","5060"); } failure_route[1] { append_branch(); t_relay_to_udp("192.168.0.39", "5060"); } Thanks in advance. Regards, Stefan

[Serusers] Radius - LDAP
by Paco Orozco 09 Dec '05

09 Dec '05

Hiya, I'm trying to use RADIUS server to authorize (authenticate) SIP users. I'm using auth_radius module. My radius server is the same machine, FreeRadius wich is configured to use LDAP as DB. Whe I try to authenticate a SIP user I've got a problem, SIP SER sends a radius request with digest method, but my Radius needs a User-Password suplied in order to bind in LDAP. How can intruct SIP SER in order to pass auth password as User-Password althout Digest??? Thanks in advance. -- ------------------------------------- Aquel que planta árboles bajo los que sabe muy bien que nunca se sentara, ha descubierto el auténtico significado de la vida.

[Users] New Feature: Supported methods and lookup
by Bogdan-Andrei Iancu 09 Dec '05

09 Dec '05

Hi, based on Juha's patch - saving in usrloc the supported methods advertised during REGISTER - I extended lookup() function to perform method based filtering. What this means: lookup() may return only contacts which supports the method of the processed request. Ex: there are two clients registering as same user: 1) a SIP phone which support INVITE & family, but no presence and messaging. 2) a soft messaging client : supports only MESSAGE When a call hits the server, the lookup() will send it only to contact (1), to the phone, since the contact (2) does not support INVITE. When a MESSAGE hits the server, the lookup() will send it only to contact (2), to the soft client, since the contact (1) does not support MESSAGE. the advantage is that you avoid un-necessary parallel forking and extra signalling. Also there are SIP implementation which does not even reply to methods they are not supporting, forcing the proxy to generate timeout..:( The feature may be turned on or off via the module parameter "method_filtering": http://www.openser.org/docs/modules/1.1.x/registrar.html#AEN247 For more, see also the script snapshot from : http://www.openser.org/docs/modules/1.1.x/registrar.html#AEN288 regards, bogdan
