Epoch current time difference
by Glaucio Vaz de Mello 10 Jan '12

10 Jan '12

Hello, I noticed a difference between FreeSWITCH time and system clock time. Is this a standard behaviour? or something is wrong in my system? More details of the issue: Inside FreeSWITCH I look for current epoch time using this function: time_t now = switch_epoch_time_now(NULL); Then I look for system clock current time using: #include <time.h> time_t now = time(NULL); Between both results I noticed a difference of 9 seconds. This can also be viewed using Unix commands. Unix date command from console: # date +%s 1314741992 Then, I start a call and make a DB query: # sqlite3 /var/freeswitch/db/core.db "SELECT call_created_epoch FROM calls;" 1314742000 Then I repeat unix date command: # date +%s 1314741994 Any comments are welcome. Regards, Glaucio

mod_portaudio multiple endpoints support
by Moises Silva 25 Oct '11

25 Oct '11

Hello, I've been doing some changes to mod_portaudio sponsored by Comrex Corporation. The changes involve adding support for using multiple audio devices simultaneously, including devices with multiple channels (note that is not exactly the same as stereo). The changes are available at git:// github.com/moises-silva/mod_portaudio-endpoints.git Complete documentation on the new functionality in portaudio can be found in the sample configuration in the form of comments (conf/autoload_configs/portaudio.conf.xml). The portaudio changes are totally backwards compatible, existing configurations should keep working as expected. In addition to the new portaudio functionality there are a few other changes that were necessary to use the new functionality. All the changes described below: 1. mod_portaudio.c and pablio.c modifications to allow usage of multiple streams, channels and devices. 2. uuid_outgoing_answer API added to mod_commands.c, this API allows to answer outgoing channels. This may only be useful for portaudio endpoints since most, if not all, endpoints receive the answer notification using some sort of signaling message (200 OK for example). 3. Changes to switch_generate_sln_silence() in switch_resample.c to allow specifying -1 as a special divisor value meaning to zero-out the buffer completely. This option was required by Comrex too since the equipment they have seems to be amplifying the random low-level noise that switch_generate_sln_silence() currently generates by default and they don't like the "hissing noise" on the background while the call is answered and there is no ringback tone. I'd appreciate anyone who can review and comment. I just merged a few moments ago with latest git therefore reviewing should be easy with git diff adding the github repo as a remote. I'd like to get approval from the core FreeSWITCH team to merge this into mainstream. Needless to say I'll be available in the case any bugs are introduced in the portaudio code, virtually impossible, but just in case :-) Thanks, - Moy

reliable way to get caller id
by adam harris 08 Sep '11

08 Sep '11

I am trying to retrieve the caller id of incoming calls and finding when I get variable Channel-Caller-ID-Number it is not the actual number of the phone that has made the call, my provider seems to be setting it another number. I am seeing the correct phome number is in the info log example below. 2011-08-23 20:40:34.832360 [INFO] mod_dialplan_xml.c:331 Processing 44203xxxxx->44800xxxx In this case is '44203xxxxx' as displayed in the info log set as channel variable?

ftdm_call_place and caller_data.call_id
by Juraj Fabo 08 Sep '11

08 Sep '11

Hi I have a question on the API delivering the generated call_id in outgoing and incoming calls. When my application makes call to ftdm_call_place status = ftdm_call_place_ex(&caller_data, &hunting, &usrmsg); caller_data.call_id is set to zero. freetdm.h description about ftdm_caller_data.call_id member explicitely states, that after the ftdm_channel_call_place() call the user can use the caller_data.call_id, otherwise the call_id from sigmsg should be used I'd like to ask only a few questions: - from sources I see, that after the ftdm_call_place_ex(..) application could use caller_data.fchan->caller_data.call_id I tested it and it was ok, please is this a proper way how to use this API function? - sigmsg's delivered to signalling callback seems again not to provide the call_id directly. From sources I found this approach to be usable when handling FTDM_SIGEVENT_START ftdm_caller_data_t * callerData = ftdm_channel_get_caller_data(p->channel); call_id = callerData->call_id; However some other events delivered the call_id directly (as p->call_id) Please, is my handling for _START event correct (despite that call to API from the callback handler is tabu) I'm working with freeswitch-snapshot 25th of May, compiling a standalone freetdm, using sangoma a102de and a104d cards. thank you very much Juraj

mod_managed not working on Linux
by Tim McQueen 05 Sep '11

05 Sep '11

I'm having a problem getting mod_managed to work on Linux. It the demo .csx file and anything I write works fine in Windows, but under Linux the same code causes a NullReferenceException. An example of the FreeSwitch log is at http://pastebin.freeswitch.org/17216. I've tried this on Ubuntu 11.04 with the stock Mono install (2.6.7) and on a fresh install of CentOS 6.0 with the latest Mono (2.10.5). Also, someone on the IRC channel is saying that mod_freeswitch isn't maintained anymore. Is this true? Thanks!
