Help on switch_channel_expand_variables(switch_channel_t *channel, const char *in)
by Alex To 21 Jan '10

21 Jan '10

Hi, Could somebody shed some lights on how the mentioned method works ? What does it do exactly ? My best guess is it takes in a channel, a string and does something to the string (escape the string ? split the string ? or something like that? But why need a channel parameter?) If there is already an explanation somewhere about this, please point it out for me or possibly just tell me what configuration should I make to trigger this method to be called. I can use debugger and figure it out by myself. Any help would be greatly appreciated. Thanks very much Regards Alex To

Openzap and intermitent ringing
by devel＠thom.fr.eu.org 19 Jan '10

19 Jan '10

So I finally could find a fix. Then problem is the ring_on and ring_off length as defined by wp_globals in ozmod_wanpipe.c For France (and I guess all other European countries), the ring on and off length shall be 1700ms and 3300ms. That correspond (at least for Europe) to the length of the ringing tone. So I was wondering I it would not be a good idea to take these values from the tones.conf file. I wonder if that is possible in wp_open_range function in ozmod_wanpipe.c. Could anybody indicate if there is any diagram of how each module in openzap calls the other, then that could be a good starting point (I dont really get the interactions/calls between ozmod_wanpipe.c and ozmod_analog.c). Also, I would need to know if this tone generation should apply to span types other than FXS. Thanks François

openzap information + mod_say_fr contribution
by devel＠thom.fr.eu.org 19 Jan '10

19 Jan '10

Hello, First let me congratulate for this great software. I was trying to diagnose a problem with my analog sangoma card, and FXS port giving intermitent ringing and not sending CLIP. I could see the intermitent ringing comes from this line. zchan->ring_time = zap_current_time_in_ms() + wp_globals.ring_on_ms; Setting zchan->ring_time could solve my problem, so could anybody indicate how to configure ring_on_ms (preferably in an XML configuration) The second point about CLIP is more difficult. First, let me indicate that Im residing in France and therefore using carrier and phones complying to european standard. About CLIP, I could see the V23 standard modulating frequencies are being populated (in fsk_modem_definitions in fsk.c). However, in zap_channel_send_fsk_data in zap_io.c, I could see that the BELL standard is hardcoded. Replacing the modem type with FSK_V23_FORWARD_MODE2 (which by what I could read seem to apply to me), I could see no difference. As I could not find as much relevant information as I would like in V23 (apart from the frequencies for the FSK), I was wondering what were I could find some information that could help to fix this. I dont know exactly what carrier_bits_start, carrier_bits_stop and chan_sieze_bits refer to, but I could find in that document (http://www.cs-strumentazione.com/manuali_pdf/clip.pdf) that « The Channel Seizure is present only in FSK-V23 Protocol. It consists in a series of 90 to 300 alternate SPACE/MARK bits » Considering this, I guess that I should use the else branch in the test « zchan->token_count > 1 ». What does this token_count refer to and where should I set it. Im still trying to figure this out (and will of course contribute the result of all this), so any help appreciated. I also did a contribution to mod_say_fr (to take into account the specific french idioms in saying date and time). Could you please tell me how to contribute this ? Thanks in advance François

Autoconfig problem on FC12
by Eric Varsanyi 19 Jan '10

19 Jan '10

I'm building freeswitch RPM packages using the sipxecs build system and the rpm packaging step was failing because libjs.so was not being built. After some digging it looks to me like a dependency problem in the libjs autoconfig setup. The patch below works around the issue but there's likely a better way. -Eric Varsanyi Details: The proximal issue is that EGREP is not defined when checking for the ability to make shared libs. The problem is some sort of dependency issue between AC_CHECK_HEADER and AC_PROG_LIBTOOL. It appears that using AC_CHECK_HEADER at 'autoconf' time remembers that the check for, say, EGREP has been done and prevents it from being issued again in the resulting configure script, however if AC_CHECK_HEADER is used in a runtime 'if' block (the 'if' runs when configure runs, not autoconf) and that if does not pay off AC_PROG_LIBTOOL ends up w/o EGREP defined and the check if we can build a shared library fails (and thus no .so is built). A simple workaround is to move AC_PROG_LIBTOOL up above the AC_ARG_WITH([dso ... check which uses AC_CHECK_HEADER in a bash if block (which does not pay off on linux). I'm no autoconf wizard and my lame attempts to force it to check for EGREP again failed -- it may be you're just not supposed to use some things inside an 'if' block at 'configure' time.

Understansing of mod_flite Config
by Suneel Papineni 19 Jan '10

19 Jan '10

Hi, I am trying to test mod_flite to announce a message like "You are 5th in Queue". mod_flite is compiled properly. I am using Windows OS and event sockets to send the commands. A dial-plan is written to park all calls that are coming to Freeswitch. After call is parked I am sending message to play the announcement. sendmsg [callID] call-command: execute execute-app-name: speak execute-app-arg: 'Hi you are 5th in Queue' This is giving an error in FS as: 2010-01-19 15:40:37.814740 [ERR] mod_dptools.c:1505 Invalid Params! [NULL][NULL][Hi you are 5th in Queue] I tried to debug this, but failed to find the issue. It seems as one argument is passed, engine and voice are null, so this error is thrown ( I assume ). Tried to send message like "execute-app-arg: 'flite'|'david'|'Hi you are 5th in Queue'". This took as 3 arguments but still thrown an error saying "Invalid speech module(flite)". Could you please let me know where I am going wrong. Also where do I need to configure engine and voice parameters, so that system could pick up automatically. Tried to set these parameters in conference.conf.xml, but not worked.

switch_ivr_originate.c(2621) uninitialized local variable 'b_frame'
by Paul Li 15 Jan '10

15 Jan '10

I am having trouble to build FreeSwitch due to the following error: c:\dev\voip\freeswitch\src\switch_ivr_originate.c(2621): warning C4701: potentially uninitialized local variable 'b_frame' used c:\dev\voip\freeswitch\src\switch_ivr_originate.c(2621): error C2220: warning treated as error - no 'object' file generated I am using Visual Studio 2008. I could disable "warning treated as error" to continue compiling. But, I don't know this warning would ultimately cause any trouble later. I am raising this problem for other developers' attention on "potentially uninitialized variable".
