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

bounty request - sofia to not route MESSAGE [was] Chat Dialplan
by david varnes 14 Aug '11

14 Aug '11

I raised a bounty jira http://jira.freeswitch.org/browse/FS-3408 which is a request to modify the native sofia treatment of incoming MESSAGE, and generate some events to allow alternate handling. I also added it to the bottom of http://wiki.freeswitch.org/wiki/Bounty I was just reading back through the list and saw this discussion, it seems pretty much what Kurtis was suggesting as well ? Given the rest of the previous thread, is this request (FS-3408) likely to get any traction ? Is there anything else I should/could do to get a yes/no answer. The reason I ask is that I have a client that would like to use this kind of feature, and will try and do the modification themselves if the change does not fit with FS dev direction. I think it would be much better if the change was available in FS though. What amount of work would it be ? thanks for any feedback :-) davidv On 7 July 2011 10:50, Kurtis Heimerl <kheimerl(a)cs.berkeley.edu> wrote: > Let me repeat myself: the changes I am proposing will be backwards > compatible.

Sipx TLS connections make Freeswitch crash
by barisyanar 11 Aug '11

11 Aug '11

Hi all, I am using Freeswitch 1.0.7 with sipx release-4.4. Whenever I try to make an IVR call with TLS, Freeswitch crashes dumping the attached core file. The output bt command is: #0 __strchr_sse42 () at ../sysdeps/x86_64/multiarch/strchr.S:131 #1 0x00007f9c0b4373c3 in sofia_glue_get_url_from_contact (buf=0x0, to_dup=0 '\000') at sofia_glue.c:4943 #2 0x00007f9c0b438e1b in sofia_overcome_sip_uri_weakness ( session=0x7f9c04017108, uri=<value optimized out>, transport=SOFIA_TRANSPORT_TCP_TLS, uri_only=SWITCH_TRUE, params=0x0) at sofia_glue.c:1296 #3 0x00007f9c0b4182b0 in sofia_handle_sip_i_invite (nua=0x7f9c04008890, profile=0x148dad0, nh=0x7f9c00009ec0, sofia_private=<value optimized out>, sip=<value optimized out>, tags=<value optimized out>) at sofia.c:6793 #4 0x00007f9c0b433aca in sofia_event_callback (event=nua_i_invite, status=100, phrase=0x7f9c0000ab40 "Trying", nua=0x7f9c04008890, profile=0x148dad0, nh=0x7f9c00009ec0, sofia_private=0x0, sip=0x7f9c00006658, tags=0x7f9c0000ab30) at sofia.c:942 #5 0x00007f9c0b4a5f53 in nua_application_event (dummy=<value optimized out>, sumsg=<value optimized out>, ee=0x7f9c0000ab08) at nua_stack.c:393 #6 0x00007f9c0b503974 in su_base_port_execute_msgs (queue=0x0) at su_base_port.c:280 #7 0x00007f9c0b503ec1 in su_base_port_step (self=0x7f9c040010f0, tout=0) at su_base_port.c:473 #8 0x00007f9c0b42d4ea in sofia_profile_thread_run ( thread=<value optimized out>, obj=0x148dad0) at sofia.c:1623 #9 0x0000003efd2068e0 in start_thread (arg=0x7f9c18116710) ---Type <return> to continue, or q <return> to quit--- at pthread_create.c:297 #10 0x0000003efcee0c9d in clone () And sipx's freeswitch log prints the line: 2011-05-16 15:04:51.530426 [WARNING] switch_core.c:1120 Cannot locate domain deneme.deneme.karelarge.com, where deneme.deneme.karelarge.com is my fqdn. No problem occurs during TCP connection. Problem is possibly caused by sipx, but i'll be glad to hear FS community's ideas.

27 Jul '11

Hey all, We are having a simple FreeSWITCH conf call today: http://wiki.freeswitch.org/wiki/FS_weekly_2011_07_27 I want to talk about mod_fifo specifically and call queuing in general. If you use mod_fifo at all please join us. There have been a lot of updates to mod_fifo that make it more "ACD-like" but the wiki page needs some serious attention. Please hop on and help us get the page updated. Thanks! -MC

Wait times
by Matthew Margolis 26 Jul '11

26 Jul '11

Is there any way to set a fifo queue to automatically tell callers on hold an approximate time they have left to wait every minute? Something like "Thank you for holding, your current wait time is 'X' minutes." If this feature doesn't exist, it would probably be very useful.
