[Freeswitch-dev] Valet Parking improvements
by Josh M. Patten 12 Apr '11

12 Apr '11

Our development team is in the process of writing some improvements into the valet parking module that we hope to get pushed upstream to the community. Among these improvements are: * Ability to set timeout value o Ability to send call back to extension that originally parked the call after timeout o Ability to send call to static extension (for example, an operator) after timeout o Ability to disconnect the call after timeout * Ability to set escape button, such as *, #, 0-9 o Ability to send call back to extension that originally parked the call after caller presses escape button o Ability to send call to static extension (for example, an operator) after caller presses escape button o Ability to disconnect the call after caller presses escape button In order to make these changes we are going to have to add a few arguments to the module. My questions are: How should we get this code submitted for review and testing? What do we need to do to get this code merged after it is reviewed and tested? Thanks!

[Freeswitch-dev] Questions on implementing mod_nelly codec
by Richard Alam 12 Apr '11

12 Apr '11

Hi, We've been trying to implement a mod_nelly codec but so far has been unsuccessful. We use a Nellymoser compatible codec submitted to ffmpeg (see June 16, 2008 entry of http://ffmpeg.org/) Our plan is to use Flash using Nellymoser to connect to a conference in FreeSWITCH. The hurdle seems to be that Nellymoser decodes 64 byte nelly audio to 512 byte L16. Nellymoser is 11-Khz 8-bit per sample with 32 ptime. However, L16 implementations are all 20 ptime which have uncompressed bytes in multiples of 320. This doesn't align with what mod_nelly expects when encoding (convert 512 bytes to 64 bytes) and decoding (64 bytes to 512 bytes). Here is the SWITCH_MODULE_LOAD_FUNCTION(mod_nelly_load) [http://pastebin.freeswitch.org/15764] now. We've played around with the samples per second (SPS), actual samples per second (ASPS), bits per second (BPS), and the ptime (PTIME) but with no luck. It's either we get bad very choppy audio, incompatible destination (when codecs can't match), or no audio at all. We've managed to get the "You will now be placed into the conference" audio played correctly but the audio from the caller is bad. Just the paying of wav file from FS is correct. My question is how does transcoding works in FS? Am I correct to assume decoding as Nelly->L16 and encoding as L16->Nelly? So basically the media flow for our use case is Nelly -> L16 --> mod_conference -> L16 -> Nelly. Do I need to make the frames align? In this case, Nelly expect 256 samples per frame while L16 has 160, 320, ... samples per frame. Hope I've articulated clearly what we are trying to accomplish. Suggestions and ideas on what to try out next is much appreciated. Thanks in advance. Richard -- --- BigBlueButton http://www.bigbluebutton.org http://code.google.com/p/bigbluebutton

[Freeswitch-dev] "play_and_get_digits" blocked on call attaching to the conference.
by Min Xie 12 Apr '11

12 Apr '11

Hi, All, I am trying to execute "play_and_get_digits" on a call which is attaching to a conference. The command was sent to the channel but did not get executed immediately. I got this from the console: switch_core_session.c:954 Send signal sofia/internal/1001(a)192.168.0.16 [BREAK] Once I expel the call from the conference, the "play_and_get_digits" starts to execute. Is there a way that you can do "play_and_get_digits" on a call which is part of an active conference? Thanks!

[Freeswitch-dev] CoreDump - Possibly User Error
by Robert Huddleston 12 Apr '11

12 Apr '11

http://pastebin.freeswitch.org/15833 I was editing mod_xml_cdr config file while FreeSwitch was up and running. Tried to reconnect to fs_cli and could not connect. Found that FreeSwitch had coredumped. Tried to use GDB BT but it's complaining about some symbols missing - which is odd as I built the box from GIT and source is installed. I admit I'm a n00b when it comes to GDB and BT Any help?

[Freeswitch-dev] module load problem
by barisyanar 12 Apr '11

12 Apr '11

Hi, I compiled a module using intel ipp library and freeswitch 1.0.7 source. SWITCH_API_VERSION is 5 in switch_types.h However I cannot load the module with fs_cli. Below is the error I get: 2011-03-24 16:35:00.584545 [CRIT] switch_loadable_module.c:928 Error Loading module /opt/freeswitch/mod/mod_tri.so **Trying to load an out of date module, please rebuild the module.** How could this happen? I expect the .so file has the same API_VERSION with the freeswitch. Baris

[Freeswitch-dev] Automatic hangups?
by Mark Sobkow 07 Apr '11

07 Apr '11

Has someone over the past few months added some sort of automatic hangup feature for parked calls? Our application lets an operator log in, and parks their call until there is a customer available for them to bridge to. Previously this worked just fine -- operators could sit for minutes or hours (much to the annoyance of managers), waiting for a call. However, something has changed. Freeswitch now seems to automatically unpark the call and hang it up, even though it hasn't been told to do _anything_ by the application. -- Mark Sobkow Senior Developer MarkeTel Multi-Line Dialing Systems LTD. 428 Victoria Ave Regina, SK S4N-0P6 Toll-Free: 800-289-8616-X533 Local: 306-359-6893-X533 Fax: 306-359-6879 Email: m.sobkow(a)marketelsystems.com Web: http://www.marketelsystems.com Visit our Blog for industry related information. http://marketel-systems.blogspot.com/
