SIP INFO carrying MSML
by Owen Williams 10 Feb '11

10 Feb '11

Hi all, I'm looking into the possibility of getting basic msml support into freeswitch. We have a few applications hosted on a remote SIP Application server that already use MSML against another media server. The application acts as a back2back between a caller and the media server and sends info messages (inside an invite dialog) to the media server with the INFO sdp containing MSML (e.g. play file, join conf, etc). I'm a bit new to freeswitch but I'm guessing mod_sofia would need to modified to send info events to a new module or to the ESL, and mod_sofia also needs to be capable of receiving events to send INFOs back to the remote B2B. There was a bounty completed about 18 months ago (Generate and be notified of SIP INFO messages) however this may have been only for out of dialog INFOs. http://wiki.freeswitch.org/wiki/Bounty#Generate_and_be_notified_of_SIP_INFO… Any information as to whether the above bounty made it into trunk and how it can be enabled would be appreciated. I'd like to have a play with writing a MSML processor through ESL as I've far more experience with ESL than writing c modules. Regards, Owen

Wrong log message
by Bernhard Suttner 09 Feb '11

09 Feb '11

Hi, Just want to let you know, that the following log message is wrong: if (!strcmp(tech_pvt->remote_sdp_video_ip, rip) && atoi(rvp) == tech_pvt->remote_sdp_video_port) { switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(tech_pvt->session), SWITCH_LOG_DEBUG, "Remote video address:port [%s:%d] has not changed.\n", tech_pvt->remote_sdp_audio_ip, tech_pvt->remote_sdp_audio_port); Should be remote_sdp_video_port I guess. Best regards, Bernhard

Hi, I am new to FreeSWITCH, I was just wondering that can we initiate Best Effort SRTP offer from FreeSWITCH in the same way as Polycom phones do, i.e sending two "m=" lines for the same media, the first line having a SAVP profile, while the second one having the normal AVP profile. Kindly please let me know how can i do this. Thanks in advance. Regards, Ujjwal

C# problem for calling "freeswitch.switch_core_session_read_frame()"
by Frankie Yiu 09 Feb '11

09 Feb '11

Hi there, I would like to dial a phone number, and read the RTP package back when connected so that we can analyze the data; (to determine when we should play an audio at the right time--human or answer machine.) We found a code for IVR test (http://docs.freeswitch.org/switch__ivr_8c-source.html) Function name: switch_ivr_sound_test We would like to do the same but with C# code, but we encountered a problem when calling the function "freeswitch.switch_core_session_read_frame( ) " < in swig.cs switch_core_session_read_frame(SWIGTYPE_p_switch_core_session session, SWIGTYPE_p_p_switch_frame frame, uint flags, int stream_id) > where the second parameter--frame is a pointer to pointer of switch_frame type and in C# code, it is having a difficulty passing an object to the C++ side and keep the pointer place holder before going deeper into the C code (switch_core_io.c) 1) So is there any way I can call this function in C#? 2) Is there another function or routine that you can suggest me to for reading RTP package? Thanks, Frank

Error using gpgme in mod_python
by mbo 08 Feb '11

08 Feb '11

Hello NG, we are launching a python script which is accessing the gpgme libary for encryption/decryption : import os import gpgme from freeswitch import * ctx=gpgme.Context() ctx.get_key(’B9F2747A’) If we run this python script direcly in the command line (without "from freeswitch import *"), everything works fine. If we call the script within freeswitch using the mod_python module, we receive the following debug output, when the environment variable GPGME_DEBUG is set to „9:/tmp“: ... gpgme_op_keylist_start: enter: ctx=0x7fcd8c2078c0, pattern=B9F2747A, secret_only=0 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_pipe: enter: filedes=0x7fcd8c1e5bc8, inherit_idx=1 (GPGME uses it for reading) GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_pipe: leave: read=0x1a5, write=0x1a6 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_set_close_notify: enter: fd=0x1a5, close_handler=0x7fcd84074420/0x7fcd8c1e5ba0 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_set_close_notify: error: Invalid argument GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_close: enter: fd=0x1a5 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_close: leave: result=0 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_close: enter: fd=0x1a6 GPGME 2011-02-07 21:40:58 <0x3b06> _gpgme_io_close: leave: result=0 GPGME 2011-02-07 21:40:58 <0x3b06> gpgme_op_keylist_start: error: General error <GPGME> GPGME 2011-02-07 21:40:58 <0x3b06> gpgme_release: call: ctx=0x7fcd8c2078c0 GPGME 2011-02-07 21:40:58 <0x3b06> gpgme_get_key: error: General error <GPGME> ...

switch_xml_config.c
by Gilles Depatie 06 Feb '11

06 Feb '11

Hi I'm running into what appears to be a questionable range interpretation issue in switch_xml_config_parse_event function. When enforce_min and enforce_max are TRUE should the value not be inclusive of MIN and MAX? Say a value range of min = '0' and max = '1000', should values of 0 and 1000 not be acceptable? The current statement: if ((int_options->enforce_min && !(intval > int_options->min)) || (int_options->enforce_max && !(intval < int_options->max))) excludes those values presently The error message seems to imply that the range is inclusive of the min and max values I've had a look at the latest git version or the file and in this respect nothing has changed from the version I am currently using GILLES Gilles Depatie, Senior S/W Designer, MapleWorks Technology O: 819-776-6066 x353 | gilles.depatie(a)mapleworks.com
