[Freeswitch-dev] hello and question
by Matthew Kaufman 04 Jun '08

04 Jun '08

I've been watching Freeswitch as a potential user for a while now (I used Asterisk for my last telephony project, Podlinez.net) but now I have need to do some even lower-level development and it looks like Freeswitch is a better choice than Asterisk... save one thing: Where the heck is the documentation that a (C/C++) module-writer needs? I've started writing a new endpoint module, and I'm making pretty good progress by reading the source code for other modules, but I have looked and looked and can't find a good reference for "these are the switch functions that are private, these are the switch functions you call if you're an endpoint module, these are the events you'll be sent if you're an endpoint module, etc." Speaking of which, a slightly different architecture/coding style might have made the interfaces between the modules and the insides more immediately clear... but in lieu of that, a good set of docs is going to be mandatory for people in my position. As it is, I'm doing ok, but my time is very valuable and not well-spent by figuring this stuff out from the source code instead of looking at the reference docs. So, is there documentation that I just haven't found the secret link to? If there isn't, is there someone who knows this stuff who can whip up a short list of things I might need to know (especially "gotchas") as an endpoint developer to save me some time?

[Freeswitch-dev] mod-java - playAndGetDigits() prototype change
by jonathan augenstine 29 May '08

29 May '08

I was encountering some strange behavior in my IVR script. What I finally tracked it down to is that the prototype on the playAndGetDigits() method has changed. The previous prototype was of the form playAndGetDigits(int, int, int, int, String, String, byte[], String) and the new prototype is playAndGetDigits(int, int, int, int, String, String, String, String). The byte array parameter has been removed and this was the parameter that returned the DTMF digits. With this parameter removed, how do I retrieve the DTMF digits? Jonathan

[Freeswitch-dev] Normalizing sound files
by Wasim Baig 29 May '08

29 May '08

We used to do the following for prompts 1. noise gate, say at -40db with a fairly quick attack 2. normalize, or use a compressor with agc 3. trim both ends silence 4. add .25 seconds of silence on both ends (may want to skip this for numbers) 5. depending on the media, you can use eq to get rid of say everything below 300hz for gsm, etc, its a good idea to boost the highs and cut the lows at this time also for crySStal clear prompts (opposite of a de-esser) this can all be automated through sox or soundforge On 5/28/08, Michael Collins <mcollins(a)fcnetwork.com> wrote: > You rock da hizzouse! > > > > ________________________________ > > From: freeswitch-dev-bounces(a)lists.freeswitch.org > [mailto:freeswitch-dev-bounces@lists.freeswitch.org] On Behalf Of Brian > West > Sent: Wednesday, May 28, 2008 2:51 AM > To: freeswitch-dev(a)lists.freeswitch.org > Subject: Re: [Freeswitch-dev] Normalizing sound files > > > > http://svn.freeswitch.org/svn/sounds/trunk/en/us/callie/dist.sh > > > That script with sox shows how we do this. > > > On May 28, 2008, at 2:36 AM, Michael Collins wrote: > > When you get new prompts you mentioned that you "normalize" them so that > the sound level doesn't vary from one prompt to the next.

[Freeswitch-dev] Normalizing sound files
by Michael Collins 28 May '08

28 May '08

Guys, When you get new prompts you mentioned that you "normalize" them so that the sound level doesn't vary from one prompt to the next. I have a set of prompts that GM Voices recorded specifically for me, but I haven't normalized them yet. Could you let me know what process you use for this? Thanks! -MC

[Freeswitch-dev] Minor suggestion: s/depricate/deprecate/g
by Michael Collins 27 May '08

27 May '08

FYI, Just to add a little professional polish we might want to replace "depricate" with "deprecate" since the former is a misspelling. Before I make a patch I wanted to know about stuff like this: [root@freeswitch2 include]# grep -rin "depricate" *h switch_config.h:41: * This module implements a basic interface and file format parser it may be depricated in favor of database entries switch_core.h:973:SWITCH_DECLARE(switch_hash_index_t *) switch_hash_first(char *depricate_me, _In_ switch_hash_t *hash); I don't favor mass-replacing variable names when I'm not the author. If someone out there is capable then here's a list of source files that have "depricate" in them: grep -ir "depricate" * |grep -v "Binary" src/include/switch_config.h: * This module implements a basic interface and file format parser it may be depricated in favor of database entries src/include/.svn/text-base/switch_core.h.svn-base:SWITCH_DECLARE(switch_ hash_index_t *) switch_hash_first(char *depricate_me, _In_ switch_hash_t *hash); src/include/.svn/text-base/switch_config.h.svn-base: * This module implements a basic interface and file format parser it may be depricated in favor of database entries src/include/switch_core.h:SWITCH_DECLARE(switch_hash_index_t *) switch_hash_first(char *depricate_me, _In_ switch_hash_t *hash); src/mod/applications/mod_commands/mod_commands.c: SWITCH_ADD_API(commands_api_interface, "killchan", "Kill Channel (depricated)", kill_function, KILL_SYNTAX); src/mod/applications/mod_commands/mod_commands.c: SWITCH_ADD_API(commands_api_interface, "transfer", "Transfer (depricated)", transfer_function, TRANSFER_SYNTAX); src/mod/applications/mod_commands/mod_commands.c: SWITCH_ADD_API(commands_api_interface, "session_displace", "session displace (depricated)", session_displace_function, DISPLACE_SYNTAX); src/mod/applications/mod_commands/mod_commands.c: SWITCH_ADD_API(commands_api_interface, "session_record", "session record (depricated)", session_record_function, SESS_REC_SYNTAX); src/mod/applications/mod_commands/mod_commands.c: SWITCH_ADD_API(commands_api_interface, "broadcast", "broadcast (depricated)", uuid_broadcast_function, BROADCAST_SYNTAX); src/mod/applications/mod_commands/mod_commands.c: SWITCH_ADD_API(commands_api_interface, "hold", "hold (depricated)", uuid_hold_function, HOLD_SYNTAX); src/mod/applications/mod_commands/mod_commands.c: SWITCH_ADD_API(commands_api_interface, "media", "media (depricated)", uuid_media_function, MEDIA_SYNTAX); src/mod/applications/mod_commands/.svn/text-base/mod_commands.c.svn-base : SWITCH_ADD_API(commands_api_interface, "killchan", "Kill Channel (depricated)", kill_function, KILL_SYNTAX); src/mod/applications/mod_commands/.svn/text-base/mod_commands.c.svn-base : SWITCH_ADD_API(commands_api_interface, "transfer", "Transfer (depricated)", transfer_function, TRANSFER_SYNTAX); src/mod/applications/mod_commands/.svn/text-base/mod_commands.c.svn-base : SWITCH_ADD_API(commands_api_interface, "session_displace", "session displace (depricated)", session_displace_function, DISPLACE_SYNTAX); src/mod/applications/mod_commands/.svn/text-base/mod_commands.c.svn-base : SWITCH_ADD_API(commands_api_interface, "session_record", "session record (depricated)", session_record_function, SESS_REC_SYNTAX); src/mod/applications/mod_commands/.svn/text-base/mod_commands.c.svn-base : SWITCH_ADD_API(commands_api_interface, "broadcast", "broadcast (depricated)", uuid_broadcast_function, BROADCAST_SYNTAX); src/mod/applications/mod_commands/.svn/text-base/mod_commands.c.svn-base : SWITCH_ADD_API(commands_api_interface, "hold", "hold (depricated)", uuid_hold_function, HOLD_SYNTAX); src/mod/applications/mod_commands/.svn/text-base/mod_commands.c.svn-base : SWITCH_ADD_API(commands_api_interface, "media", "media (depricated)", uuid_media_function, MEDIA_SYNTAX); src/mod/applications/mod_dptools/.svn/text-base/mod_dptools.c.svn-base: SWITCH_ADD_APP(app_interface, "reject", "Send session reject (depricated)", "Send a respond message to a session.", respond_function, "<respond_data>", SAF_SUPPORT_NOMEDIA); src/mod/applications/mod_dptools/mod_dptools.c: SWITCH_ADD_APP(app_interface, "reject", "Send session reject (depricated)", "Send a respond message to a session.", respond_function, "<respond_data>", SAF_SUPPORT_NOMEDIA); src/mod/languages/mod_mono_managed/swig/.svn/text-base/freeswitch.cs.svn -base: public static SWIGTYPE_p_HashElem switch_hash_first(string depricate_me, SWIGTYPE_p_switch_hash hash) { src/mod/languages/mod_mono_managed/swig/.svn/text-base/freeswitch.cs.svn -base: IntPtr cPtr = freeswitchPINVOKE.switch_hash_first(depricate_me, SWIGTYPE_p_switch_hash.getCPtr(hash)); src/mod/languages/mod_mono_managed/swig/freeswitch.cs: public static SWIGTYPE_p_HashElem switch_hash_first(string depricate_me, SWIGTYPE_p_switch_hash hash) { src/mod/languages/mod_mono_managed/swig/freeswitch.cs: IntPtr cPtr = freeswitchPINVOKE.switch_hash_first(depricate_me, SWIGTYPE_p_switch_hash.getCPtr(hash)); src/.svn/text-base/switch_core_hash.c.svn-base:SWITCH_DECLARE(switch_has h_index_t *) switch_hash_first(char *depricate_me, switch_hash_t *hash) src/switch_core_hash.c:SWITCH_DECLARE(switch_hash_index_t *) switch_hash_first(char *depricate_me, switch_hash_t *hash) My wife says I have to go spend time with the family now so I'll catch you guys later... -MC
