Freeswitch core dumped, when setting callback to events
by lakshmanan ganapathy 11 Nov '09

11 Nov '09

Dear all, I did the below code, to callback a function when CHANNEL_EXECUTE_COMPLETE event comes. I executed the script for the 1st time and I got nothing. When I executed the script for the 2nd time, it ended with Sedmentation fault with core dumped. I was unable to attach the core dump file with this mail. Please specify how to send files to freeswitch user mailing list if need be. The freeswitch log is here: http://pastebin.freeswitch.org/11038 #!/usr/bin/perl use strict; use Data::Dumper; our $session; $session->answer(); my $events=new freeswitch::EventConsumer("CHANNEL_EXECUTE_COMPLETE"); $events->pop(1); $events->swig_e_callback_set("playvoice"); sub playvoice() { freeswitch::consoleLog("INFO","Call back function called\n"); } return 1;

Re: [Freeswitch-users] Help with dynamic IVR

As I opinion, it's not necessary write ivr script for each student. A "static" ivr script load question and response dynamic is what you need. 2009/11/11 Malay Thakershi <malay.thakershi(a)continuityhealth.com> > Hello.

Help with dynamic IVR
by Malay Thakershi 10 Nov '09

10 Nov '09

Hello. I am very new to FreeSwitch, Telephony and IVR. My goal is to prepare a student assessment IVR system as a college project. But this IVR is going to be dynamic. So for each student assessment may be different (number of questions, possible responses, flow of prompts, etc). Is it possible to achieve something like this with FreeSwitch? Most IVR we see are static (like a bank IVR system that flows always in same way). That is why I am confused. Please share your views. Malay Thakershi

Patch to fix italian pronunce in mod_say_it
by Albano Daniele Salvatore - Lavoro 10 Nov '09

10 Nov '09

Hi, yesterday i started to fix pronuce in mod_say_it for numbers, dates and times. I needed to add some sound files because these was necessary for a correct italian pronunce. I've patched these three functions: - play_group - it_say_time - it_say_general_count I've diff it against revision 15396 (i've updated freeswitch tree yesterday morning) Can you take a look to the patch? # Modification to play_group function In italian we pronunce 123 as "cento venti tre" and not "uno cento venti tre" so, if a is 1 just doesn't play the digit # Modification to it_say_time Our long date format is something like WDAY_NAME, WDAY_NUMBER MONTH_NAME YEAR so i converted the date pronunce to this. I've dropped am/pm logic, because we have 24h standard, and minutes related logic because, we don't have it. # Modification to it_say_general_count I rewrote number to string conversion to make it more readable (using just two math operations, a module and a division) and to drop the 999 milions limit (1*)(however more code should be changed to fully drop this limit). Changes are mainly related to millions and thousands pronunce: in italian, if you need to say 1 milion you doesn't say "uno milione" but "un milione" but to say 3 millions you say "tre milioni", while for thousand you doesn't pronunce "un" at all. 1*: i've noticed a little bug in xx_say_money in mod_say_xx ... it get up to 12 digits but in xx_say_general_count manage up to 9 digits, so the first three digits wouldn't get never pronunced Thank you Index: src/mod/say/mod_say_it/mod_say_it.c =================================================================== --- src/mod/say/mod_say_it/mod_say_it.c (revisione 15396) +++ src/mod/say/mod_say_it/mod_say_it.c (copia locale) @@ -95,7 +95,9 @@ { if (a) { - say_file("digits/%d.wav", a); + if (a != 1) { + say_file("digits/%d.wav", a); + } say_file("digits/hundred.wav"); } @@ -170,7 +172,7 @@ char *tosay, switch_say_type_t type, switch_say_method_t method, switch_input_args_t *args) { int in; - int x = 0; + int places_count = 0; int places[9] = { 0 }; char sbuf[13] = ""; switch_status_t status; @@ -179,26 +181,64 @@ switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Parse Error!\n"); return SWITCH_STATUS_GENERR; } - + + // Get in in = atoi(tosay); + + // Check if number too big + if (in > 999999999) { + // Fail + return SWITCH_STATUS_FALSE; + } + // Check if number isin't zero if (in != 0) { - for (x = 8; x >= 0; x--) { - int num = (int) pow(10, x); - if ((places[(uint32_t) x] = in / num)) { - in -= places[(uint32_t) x] * num; - } - } - + + // Init x to 0 + places_count = 0; + + // Loop until in is greater than zero + do { + // Get last digit + places[places_count] = in % 10; + + // Drop last digit + in = in / 10; + } + while(in > 0 && ++places_count > 0 /** fake check to put in while */); + switch (method) { case SSM_COUNTED: case SSM_PRONOUNCED: - if ((status = play_group(SSM_PRONOUNCED, places[8], places[7], places[6], "digits/million.wav", session, args)) != SWITCH_STATUS_SUCCESS) { - return status; - } - if ((status = play_group(SSM_PRONOUNCED, places[5], places[4], places[3], "digits/thousand.wav", session, args)) != SWITCH_STATUS_SUCCESS) { - return status; - } + + // Check for milions + if (places_count > 5) { + // Check if the millions digit is one (digit 6 = 1, digit 7 and 8 = 0) + if (places[6] == 1 && places[7] == 0 && places[8] == 0) { + say_file("digits/un.wav"); + say_file("digits/million.wav"); + } else { + // Play millions group (digits/million.wav should be digits/millions.wav) + if ((status = play_group(SSM_PRONOUNCED, places[8], places[7], places[6], "digits/million.wav", session, args)) != SWITCH_STATUS_SUCCESS) { + return status; + } + } + + } + + // Check for thousands + if (places_count > 2) { + if (places[3] == 1 && places[4] == 0 && places[5] == 0) { + say_file("digits/thousand.wav"); + } else { + // Play thousand group + if ((status = play_group(SSM_PRONOUNCED, places[5], places[4], places[3], "digits/thousands.wav", session, args)) != SWITCH_STATUS_SUCCESS) { + return status; + } + } + } + + // Play last group if ((status = play_group(method, places[2], places[1], places[0], NULL, session, args)) != SWITCH_STATUS_SUCCESS) { return status; } @@ -370,36 +410,19 @@ if (say_date) { say_file("time/day-%d.wav", tm.tm_wday); + say_num(tm.tm_mday, SSM_PRONOUNCED); say_file("time/mon-%d.wav", tm.tm_mon); - say_num(tm.tm_mday, SSM_COUNTED); say_num(tm.tm_year + 1900, SSM_PRONOUNCED); } if (say_time) { - int32_t hour = tm.tm_hour, pm = 0; + say_file("time/hours.wav"); + say_num(tm.tm_hour, SSM_PRONOUNCED); - if (hour > 12) { - hour -= 12; - pm = 1; - } else if (hour == 12) { - pm = 1; - } else if (hour == 0) { - hour = 12; - pm = 0; - } - - say_num(hour, SSM_PRONOUNCED); - - if (tm.tm_min > 9) { + if (tm.tm_min) { + say_file("time/and.wav"); say_num(tm.tm_min, SSM_PRONOUNCED); - } else if (tm.tm_min) { - say_file("time/oh.wav"); - say_num(tm.tm_min, SSM_PRONOUNCED); - } else { - say_file("time/oclock.wav"); } - - say_file("time/%s.wav", pm ?

Dialplans and XML_CURL
by Jonathan Pitcher 10 Nov '09

10 Nov '09

Good morning everyone. I have a question regarding using MOD XML_CURL and returning a dial plan. I have my system setup to respond with the following dialplan. <?xml version="1.0"?> <document type="freeswitch/xml"> <section name="dialplan" description="Regex/XML Dialplan"> <context name="default"> <extension name="one"> <condition field="destination_number" expression="^(.*)$">  </condition> </extension> <extension name="two"> <condition field="destination_number" expression="^(.*)$">  </condition> </extension> <extension name="three"> <condition field="destination_number" expression="^(.*)$">  </condition> </extension> </context> </section> </document> My question is this. Can extension one, use extension two and three without XML_CURL making another dialplan request? Thanks, Jonathan Pitcher

Mod Voicemail, Is it just for registered users?
by Shameem Shiek 10 Nov '09

10 Nov '09

Dear Freeswitch users, I am building an app where the extensions map to external callers and there are no registered users. For example, the extension 1001 would map to an external number. In that case, does it make sense to use the Mod voicemail or should I build a voicemail solution using dialplan/commands ? I need a voicemail solution to email voice messages. Thanks in advance for your input.

Hi! I'm trying the Doodle web SIP phone but for some reason I'm unable to register to my FreeSWITCH server. I've tried with other servers and it works ok. Did someone tried this web phone with FreeSWITCH? Any tips why it doesn't authenticate? Thank you! Federico Omoto
