Following is the js i am using to select route and bridge the call.... use("ODBC"); var DSN = "myodbc"; var DB_USER = "neo"; var DB_PASS = "....."; var sql; var prefix1; var ip1; var no2; var bridge_str; if(argv[0]=="") exit(); if(argv[1]=="") exit(); ip1 =argv[0].split("@")[1]; var no1=argv[1]; var sql = "SELECT id,prefix,name FROM internal_auth where substring('"+no1+"',1,length(prefix))=prefix and ip='" + ip1 +"' and active=1;"; var authName=""; var db = new ODBC(DSN, DB_USER, DB_PASS); db.connect(); db.query(sql); if(db.nextRow()) { var row = db.getData(); if (row["id"] == "" ) { console_log("Err", "auth failed(0001)\t" + no1 + "\targ[0]=>" + argv[0] + "\targ[1]=>" + argv[1] + "\n"); db.close(); exit(); } prefix1=row["prefix"]; authName=row["name"]; }else{ console_log("Err", "auth failed(0001)\t" + no1 + "\targ[0]=>" + argv[0] + "\targ[1]=>" + argv[1] + "\n"); db.close(); exit(); } no2=no1.substring(prefix1.length, no1.length); sql = "SELECT ec.* FROM auth_routes_carriers arc,external_carriers ec, codes c where arc.external_carriers_id = ec.id and arc.code_id = c.id and substring('"+no2+"',1,length(c.code))=c.code and ec.active=1 order by arc.priority asc"; db.connect(); db.query(sql); var carriersName=""; bridge_str=''; while(db.nextRow()) { var row = db.getData(); if (row["id"] != "" ) { bridge_str = row["gateway"]+row["prefix"]+no2+"\@"+row["ip"]; carriersName = row["name"]; break; } } db.close(); if(bridge_str != ''){ if(session.ready()) session.execute("bridge", bridge_str); } else { console_log("Err", "external carrier not found.\t" + no2 + "\targ[0]=>" + argv[0] + "\targ[1]=>" + argv[1] + "\n"); exit(); } exit();

Could it be that you are getting several INVITE messages per call due to 100 Trying message is not being sent until after the route is selected from your java routing script? You might be able to send a 100 trying from your dialplan or script. Keep in mind that this message stops timers on the originating side. - original message - Subject: Re: [Freeswitch-users] Freeswitch creating more then two sessions for one call From: Michael Jerris <mike(a)jerris.com> Date: 05/06/2009 20:27 On Jun 5, 2009, at 4:11 PM, Shoaib Khanzada wrote: > Thanks for the reply…. > > I was not running it for testing purpose because I’ve completed all > testing successfully. > > We are running freeswitch in a voip carrier grade environment.

It creates a session when it gets an incomming call and creates one for each outgoing call, unrelated to bridging. > > Thanks, > > Shoaib How are you doing the bridge in your script? Are you setting a var then dropping out of the js to do the bridge? Can you post your js file?

GnuGK vs FreeSWITCH
by Marcus Frenkel 05 Jun '09

05 Jun '09

Hi, I'm using GnuGK H323 gatekeeper. It has good performance and many features, but doesn't supports SIP. I see many Asterisk vs FreeSwitch comparisons, but how about GnuGK vs FreeSwitch? The setup for which I'm asking is in a range of 200 concurrent calls. The points that I'm really interested for comparison are: 1) Proxy of RTP feature and it's stability 2) NAT support 3) Direct SQL AAA support (without the need of using RADIUS server) 4) Performance as an endpoint registrar 5) Rerouting to a second carrier on failed call Also, is the H323 library of FreeSWITCH based on h323plus/openh323?

Freeswitch creating more then two sessions for one call
by Shoaib Khanzada 05 Jun '09

05 Jun '09

Thanks for the reply…. I was not running it for testing purpose because I’ve completed all testing successfully. We are running freeswitch in a voip carrier grade environment. It works perfectly alright in off peak hours when we have low calls ratio around 100-150 concurrent calls. However, in peak hours this goes beyond 200 calls and on that point freeswitch start creating many sessions for each calls. I have seen the sessions using “status” command and calls using “show calls count”. We are using javascript to select the route from the mysql database for each call. Could it be because script is taking longer than expected amount of time to retrieve a route? and freeswitch continuously keep creating sessions for incoming calls. That’s why I see low no of connected calls (if ‘show calls count’ only display the connected calls) whereas sessions are continuously being created by freeswitch as it is receiving many calls. If above text confuses you, nevermind just answer the following questions. 1) Does ‘show calls count’ display the connected calls only? 2) When freeswitch create session instances? Before bridge or after bridge? Or one before bridge and one after bridge? Thanks, Shoaib

Using setGlobalVar and getGlobalVar
by Shoaib Khanzada 05 Jun '09

05 Jun '09

Hi, How can I use setGlobalVar and getGlobalVar in my javascript to store a ODBC connection? I want to set an ODBC database connection object globally so that I can access it from anywhere. This connection will be used for read-only so no threading issues. Shoaib

Reuse ODBC connection in javascript
by Shoaib Khanzada 05 Jun '09

05 Jun '09

Hi, I want to reuse database connection (mysql) in one of my javascript which is executed on each call. Following is how I am creating ODBC connection. Line1) var db = new ODBC(DSN, DB_USER, DB_PASS); Line2) db.connect(); My first question is, where does it create a database connection on line1 or on line2? Secondly, how can I reuse this connection? so that it is not created for each call and I just use a previously created <code>db</code> object in my routing script. My Objective is: 1) Create ODBC connection on freeswitch startup (could be a database connection pool) 2) Reuse the connection on each call 3) Close database connection on freeswitch shutdown (or on some other event) Any help would be highly appreciated. Shoaib
