Lua XML parser
by Glen Ganderton 13 Sep '11

13 Sep '11

Hey Guys, I'm currently trying to create a basic IVR with voice recognition (just a simple YES or NO response). I have successfully configured the freeswitch MRCP client to connect to my nuance MRCP server and I successfully get a responses from the server. Now what I need to do is process the response in my freeswitch lua script. The nuance box returns the following: ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Completion-Cause: 000 success Content-Type: application/nlsml+xml Content-Length: 178 <?xml version='1.0'?><result><interpretation grammar="session:nuance5-mrcp2" confidence="0.99"><input mode="speech">yes</input><instance>true</instance></interpretation></result> Now what I want to be able to do is parse the XML in my lua script so that I can simply have the XML stored in some variables: Eg. Confidence = 0.99 Input = yes Instance = true ....etc. I am just starting to learn lua and am unable to do this myself. I have seen a few scripts online to parse XML for lua but none seem to work correctly (maybe they are meant for different format..not sure). If anybody could point me in the right direction or write some sample code for what I need to do that would be a great help. Thanks in advance. -Glen

txfax() over loopback
by Isaac Jurado 13 Sep '11

13 Sep '11

Hi, I've been trying to combine mod_loopback and mod_spandsp very similarly to the way it is explained here: http://jira.freeswitch.org/browse/FS-3494 However, I cannot manage to make any case work, except for the direct one not using loopback. I've checked the issue's configuration files and all, and they don't seem to hide any particular variable. I'm using a git checkout from may 30th of this year. The issue has been fixed in august. However, I was wondering if between may and august this scenario was not supposed to work. Cheers. -- Isaac Jurado Internet Busines Solutions eConcept

How to use sofia_count_reg ?
by Avi Marcus 13 Sep '11

13 Sep '11

I'm trying to use the API sofia_count_reg but all I'm getting is an error or -1. If I do "sofia_count_reg 1000" - whether there's multiple bindings or the user doesn't exist, I get -1. When I try "sofia_count_reg 1000(a)domain.com" I get an sql error: 2011-09-08 08:22:29.381355 [ERR] switch_core_sqldb.c:825 ERR: [select count(*) from sip_registrations where (sip_user='' or dir_user='1102') and (sip_host='1102' or presence_hosts like '%sip.getbestfone.com%')] [STATE: 42S22 CODE 1054 ERROR: [unixODBC][MySQL][ODBC 3.51 Driver][mysqld-5.1.41-3ubuntu12.10-log]Unknown column 'dir_user' in 'where clause' Thanks! -Avi

fs_curl
by Chris Martineau 13 Sep '11

13 Sep '11

Hi, Wanted to download fs_curl to have a play with but cannot seem to download it as a complete app. Not used fisheye before so cannot see how to git or svn from it and have tried various ways but the only way I can see of getting the file contents is to stick the source on fisheye to raw and copy it file by file! If someone can provide a git or svn link to get the latest version it would be greatly appreciated. Many thanks Chris

User Agent Displayed by sipsak
by cogs66 13 Sep '11

13 Sep '11

Hi Very much learning here and working on security at present. I have used sipsak to see what is displayed to the outside world. Whilst I am proud to be using FreeSWITCH I am concerned this is too much info? User-Agent: FreeSWITCH-mod_sofia/1.0.head-git-db88cd3 2011-08-25 13-27-11 -0500 I also notice SIP/2.0 200 OK. When I run on a provider I see SIP/2.0 501 Method not allowed. Maybe this is because they use a SIP proxy and I am not here. Maybe this is nothing to worry about but I would rather be sure and would appreciate any feedback here. Cheers A -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/User-Agent-Displayed-by-sipsa… Sent from the freeswitch-users mailing list archive at Nabble.com.

ESL Send MESSAGE_WAITING Error - Cannot find profile
by Avi Marcus 13 Sep '11

13 Sep '11

I'm trying to send a MESSAGE_WAITING via ESL on multi-tenant, but I'm getting this error: 2011-06-27 10:46:25.443081 [ERR] sofia_presence.c:405 Cannot find profile 20064.domain.com] the cli lists the domain as an alias to the internal profile. what should I do? I am writing some test code in order to try to send MWI events using the ESL Manager code DLL. Here is my test code: static void InboundMode2(Object stateInfo) { //Initializes a new instance of ESLconnection, and connects to the host $host on the port $port, and supplies $password to freeswitch ESLconnection eslConnection = new ESLconnection(myinfo); if (eslConnection.Connected() != ESL_SUCCESS) { Console.WriteLine("Error connecting to FreeSwitch"); return; } //Set log level //ESL.eslSetLogLevel((int)enLogLevel.DEBUG); eslConnection.Api("reloadxml", string.Empty); // Subscribe to all events ESLevent eslEvent2 = eslConnection.SendRecv("event plain ALL"); if (eslEvent2 == null) { Console.WriteLine("Error subscribing to all events"); return; } ESLevent eslEvent = new ESLevent("MESSAGE_WAITING", null); eslEvent.AddHeader("MWI-Messages-Waiting", "yes"); eslEvent.AddHeader("MWI-Message-Account", "103(a)20064.domain.com<103(a)20064.cmvtesttele.com> "); eslEvent.AddHeader("MWI-Voice-Message", "1/1 (1/1)"); eslEvent = eslConnection.SendEvent(eslEvent); if (eslEvent == null) { Console.WriteLine("event error"); return; } //Turns an event into colon-separated 'name: value' pairs. The format parameter isn't used Console.WriteLine(eslEvent.Serialize(String.Empty)); // Grab Events until process is killed while (eslConnection.Connected() == ESL_SUCCESS) { eslEvent = eslConnection.RecvEvent(); Console.WriteLine(eslEvent.Serialize(String.Empty)); } } When I send the event, I am getting a debug message from FS as follows: 2011-06-27 10:46:25.443081 [ERR] sofia_presence.c:405 Cannot find profile 20064.domain.com] Thanks! -Avi

Lua "two steps" bridging
by chrisbware＠interfree.it 13 Sep '11

13 Sep '11

Hi guys, I've read anything on this argument on Wiki but I can't find a complete answer. I need to bridge two calls in Lua, waiting the first to be answered. My basic script is: local GwParams = "origination_caller_id_number="..gateway..",sip_auth_username="..gateway..",sip_auth_password="..sip_passwd local slegA = "[ignore_early_media=false,"..GwParams.."]sofia/external/"..callee.."@"..sip_domain local slegB = "[ignore_early_media=true,"..GwParams.."]sofia/external/"..called.."@"..sip_domain legA = freeswitch.Session(slegA); legB = freeswitch.Session(slegB); freeswitch.bridge(legA, legB); It works but legA and legB are called at the same time. Using: while (legA:answered()== false) do end; between the two session do the job but called parties can't hear audio. I promise to add a script on wiki if you help me ! :) Thanks in advance. ------------------------------------------------------------------------------- Valore legale alle tue mail InterfreePEC - la tua Posta Elettronica Certificata http://pec.interfree.it -------------------------------------------------------------------------------

MySQL high CPU usage after Freeswitch update
by Yehavi Bourvine 13 Sep '11

13 Sep '11

Hello, This mornning I've updated our Freeswitch from a 3 months old GIT to yesterday's GIT (git-2fa8f11 2011-09-09 14-50-54 -0700). We are using MySQL via ODBC, and I noticed that since today's mornning MySQL is eating 300% CPU (I have 16 cores total). Any idea how to locate the culprit? BTW, I did "git clone" and then install fresh bin/mod/lib directories (after deleting the previous content) just to make sure that I have no leftovers from previous version. Thanks! __Yehavi:
