[Freeswitch-dev] 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

[Freeswitch-dev] 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

[Freeswitch-dev] offering two "m=" lines from FreeSWITCH
by Ujjwal SIngh 09 Feb '11

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

[Freeswitch-dev] 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

[Freeswitch-dev] 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> ...

[Freeswitch-dev] 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

[Freeswitch-dev] FreeSwitch and simple encryption
by Dmitry Mordovin 04 Feb '11

04 Feb '11

Hello, I wish to implement some simple encryption stuff into FS. My Idea: Imagine, some clients who have SIP softphone with encryption (My own method and only SIP signaling packets will affected) will interconnect with FS. So, FS must decrypt this packets before proceed it and encrypt before sent to this client. Could anyone direct me to easy way to implement it? Thanks Dmitry
