[Freeswitch-dev] mod_httapi
by Karl Seacrest 09 Feb '12

09 Feb '12

Thanks Michael Collins, I am still laughing about your point: Me you telling Anthony what early media is kind of like telling a neurosurgeon that a person's brain is inside the cranium. :P Seeing the way you put it makes me laugh. sorry Anthony, i am not trying to educated you about Early Media. Michael as regards your question, i am developing a premium customer support application whereby registered members can call-in and the customer support staffs will pick the call. But before the call will connect with to live support. I want the caller id to be checked from the database if it's registered and active or not. if registered, call is connect to live support but if not, an audio will be played to the caller telling them they are not registered for the service and disconnect without the caller being charged. The only time the call will be charged is when the call connected to live support. so i am thinking using the early media mode will help me achieve this but i am not sure how to go about it using the mod_httapi. My second question is, is there any performance benefit for using mod_httapi over a framework like Plivo that provide RESTFul features to FreeSWITCH?

Re: switch_ivr_bridge.c question (Anthony Minessale) 4. mod_httapi (Karl Seacrest) Actually, Anthony understood your question and gave you a solution with bonus information. I especially liked the part where you tell Anthony what early media is. That's kind of like telling a neurosurgeon that a person's brain is inside the cranium. :P If you issue a playback without actually answering the call then the net effect is that you are pre_answering the call and the file you are playing is in early media, i.e. you have not actually "answered" the call from a billing perspective. From the caller perspective the file you play is the ringback that they will hear. Is there something you were curious about beyond sending audio to the caller in early media mode? -MC On Thu, Feb 2, 2012 at 1:15 AM, Karl Seacrest <karlseacrest(a)yahoo.com> wrote: Thanks for your reply Anthony, > >But i think you didn't quite understand my question.

[Freeswitch-dev] no video in mod_fifo
by Seven Du 09 Feb '12

Hi, There's no video when bridged calls through fifo, I found no video support in the following code. I made a work around by setting sip_use_codec_name="PCMU,H264" question is will this causing problem? what's the purpose of the following code? how can I add video support ? Thanks. if ((codec = switch_event_get_header(pop, "variable_sip_use_codec_name"))) { const char *rate = switch_event_get_header(pop, "variable_sip_use_codec_rate"); const char *ptime = switch_event_get_header(pop, "variable_sip_use_codec_ptime"); char nstr[256] = ""; if (strcasecmp(codec, "PCMU") && strcasecmp(codec, "PCMA")) { switch_snprintf(nstr, sizeof(nstr), "%s@%si@%sh,PCMU@%si,PCMA@%si", codec, ptime, rate, ptime, ptime); } else { switch_snprintf(nstr, sizeof(nstr), "%s@%si@%sh", codec, ptime, rate); } switch_event_add_header_string(ovars, SWITCH_STACK_BOTTOM, "absolute_codec_string", nstr); } -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)

Hello, please tell me why the FS can not hear soft-fax (VentaFax Minioffice)? Fax automatically picks it up, but in FS it is not visible .. PS: If someone has worked with a soft-fax, what do you used? Best regards, Appalonov Andrey.

[Freeswitch-dev] FreeSWITCH Conference Call Tomorrow
by Michael Collins 07 Feb '12

07 Feb '12

Hello all! Just a reminder that we are having Travis Cross come back and talk to us about git again. I think we've all had some time to digest the information from his first presentation and hopefully we have some intelligent questions for him. I'm wondering if he can show us an example of git bisect. :) Here's the agenda page: http://wiki.freeswitch.org/wiki/FS_weekly_2012_02_08 FYI, I am trying to get caught up on the release notes so I've found a few new FreeSWITCH things that I'd like to have you all help me get documented. :) Thanks, Michael

I would like to thank everyone that has donated money to help me pay for all the expense of having a stay in the hospital. It was a pretty scary week for me last week. If it were not for the morphine last week would have sucked even more! I have missed out on the annual Developer meeting in Milwaukee this year due to this event. So please make sure you guys donate some money for the dinner for those guys. Again Thank you all for your support. -- Brian West FreeSWITCH Solutions, LLC Phone: +1 (918) 420-9266 Fax: +1 (918) 420-9267 brian(a)freeswitch.org http://www.freeswitch.org

[Freeswitch-dev] It's that time of year: Buy the devs dinner!
by Michael Collins 03 Feb '12

03 Feb '12

Hello all! Each February the FreeSWITCH team converges on a small Milwaukee suburb to plot and plan how we will continue to conquer the world of open source telephony. From personal experience I can attest to the fact that it's really difficult to conquer the world on an empty stomach. :) We'd like to invite everyone to throw a few bucks into the hat to buy dinner for the FreeSWITCH core development team. The easiest way to donate is to hit the gold "donate" button on the right-hand side of the main FreeSWITCH page. Be sure to include a memo line, something like "bon appetit," so that we can keep track. Thanks again for supporting the FreeSWITCH team! We have an awesome community and you continue to show it on a daily basis. -Michael

[Freeswitch-dev] switch_ivr_bridge.c question
by Darren C. 02 Feb '12

02 Feb '12

OS is Centos 5.7. Most recent GIT has same code. In switch_ivr_bridge.c on line 1474, we have the following lines of code: switch_channel_clear_state_handler(originator_channel, NULL); switch_channel_clear_state_handler(originatee_channel, NULL); switch_channel_set_state_flag(originator_channel, CF_BRIDGE_ORIGINATOR); switch_channel_clear_flag_recursive(originatee_channel, CF_BRIDGE_ORIGINATOR); switch_channel_add_state_handler(originator_channel, &uuid_bridge_state_handlers); switch_channel_add_state_handler(originatee_channel, &uuid_bridge_state_handlers); Is the call to “switch_channel_set_state_flag” a typo? Since it triggers an asynchronous flag change on the channel thread, and at least in the scenario when the asynchronous change immediately after the next “switch_channel_clear_flag_recursive”, the clearing of the flag will not do anything. Thanks in advance.
