[curl_sendfile][unable to get response]
by Bilal Abbasi 11 Oct '17

11 Oct '17

Hi Users, I am using lua script to actually call the curl_sendfile, i am able to successfully POST the file on URL, but i am only curious to know the response variables to get the status. Like i used curl previously and there are two variables that are auto set curl_response_data and curl_response_code, i am looking same in the curl_sendfile. CAn anybody help me in this? P.S: i did tried to send file using curl, but i am not aware that how to do that using the curl -F(--form) option, i can upload a file using commandline linux curl command , but could not mapp the option -F in the freeswitch. Regards Abbasi

Channel Event Issue
by Freeswitch 11 Oct '17

11 Oct '17

Hi, Yes, bgapi helps to solve the ESL issue. ESL does not block any more. However, the Channel still blocks when trying to leave the conference. During FreeSWITCH shutdown, the following issue is logged: 2017-10-09 09:42:51.115212 [NOTICE] switch_loadable_module.c:1055 Deleting Application 'conference' 2017-10-09 09:43:01.134791 [ERR] switch_loadable_module.c:1062 Giving up on 'conference' waiting for existing references. 2017-10-09 09:43:01.134791 [NOTICE] switch_loadable_module.c:1110 Deleting API Function 'conference' 2017-10-09 09:43:11.155363 [ERR] switch_loadable_module.c:1118 Giving up on 'conference' waiting for existing references. Regards, Tobias Hi, since updating from FreeSWITCH 1.6.8 to FreeSWITCH 1.6.17 (Windows Server 2012 R2), the Event Socket Handler(inbound mode) sporadically stops sending Channel related Event Info. Once in this situation, the Event Socket Handler does not recover until either reset of the ESL connection by the Host that established the ESL connection or reload of mod_event_socket. Shortly before Event Socket connection drops it seems that there is a problem trying to close a channel.

[ERR] switch_core_video.c:2879 This function is not available, libpng not installed
by Akshaya j 10 Oct '17

10 Oct '17

Hi team.! In Centos7 with libpng 1.5 version When I dial conference number I can witness an ERR [ERR] switch_core_video.c:2879 This function is not available, libpng not installed... Conference call doesn't use video its just audio call.. The calls works properly but this error bothers me of what the problem is? Someone please help in fixing this. I run another FS setup in Debian machine where there s no such error as libpng 1.6 version is available Note: libpng is up to date in my centos 7(libpng1.5 which is what available for centos7) but freeswitch needs libpng 1.6, I guess. Thanks in advance Akshaya J

Stats collection (telegraf), specifically: all limit hash results
by Avi Marcus 10 Oct '17

10 Oct '17

I see an API command to query a specific limit. When using db back end, I could query the db. Is there a way to get the whole hash back end in one shot? I only see `hash select/realm/key` in the docs. I'm looking at integrating with telegraf data collector. *Previous art for collectors:* Active channels/calls/cps here (the common ones): https://github.com/areski/freeswitch-telegraf-plugin and also active calls per profile + some history here: https://github.com/moises-silva/freeswitch-telegraf Reinman adds conference list: https://github.com/riemann/riemann-tools/blob/master/bin/riemann-freeswitch datadog: adds skipped packets, g729 channel count, events of reloadxml/modules https://github.com/wimactel/FreeSwitch-DataDog-Metrics/blob/master/metrics.… statsd: adds registration count https://github.com/sangoma/mod_statsd prometheus with registrations and channels, but custom counters instead of accesing limit: https://github.com/moises-silva/mod_prometheus

Re: [Freeswitch-users] session id (rfc7329) support (VoIP and Verto)?
by Robert Mundkowsky 09 Oct '17

09 Oct '17

Maybe a better question is there a different mechanism for tracking a SIP based call that orginated from Verto across multiple SIP based systems? I suppose Homer can be used for this, but seems like the overkill solution. -------- Original message -------- From: Michael Jerris <mike(a)jerris.com> Date: 10/9/17 2:30 PM (GMT-05:00) To: FreeSWITCH Users Help <freeswitch-users(a)lists.freeswitch.org> Subject: Re: [Freeswitch-users] session id (rfc7329) support (VoIP and Verto)? We do not, and most certainly do not in Verto as this is a SIP spec.

Auth and DNS load balancing.
by Sharath Kumar 09 Oct '17

09 Oct '17

Hello, I have the below scenario. FS talking to a service provider and the sip server has DNS load balancing. (FS) INVITE --> abc.com( ip = 10.10.10.10) 407 <------abc.com Ack-----------> abc.com INVITE(credentials)-->abc.com (ip = 11.11.11.11) 407<-------------------abc.com Ack------------> abc.com The session is destroyed at this point and Freeswitch does not resend the INVITE. I want the FS not to give up and keep the INV/407/ACK cycle going. The sofia traces indicate session terminated [904]. I understand that if DNS is going to load balance for every INVITE then the call will never be established. But I still would like to see if it can be done? Anyone else run into this issue ? thank you, Shaks.

Issue with database updates
by Rick Jarvis 09 Oct '17

09 Oct '17

Is there any reason why FS iterates through all the fields in the channels table, when it updates a field? I’ve created some custom columns (as per https://freeswitch.org/confluence/display/FREESWITCH/Variable+presence+data… <https://freeswitch.org/confluence/display/FREESWITCH/Variable+presence+data…>) but the values I’m writing to my new columns are being overwritten when FS changes the channel state - it appears from the logs that this is due to FS reading the values from the table, and then setting every column (including my custom fields) when it then updates … to me this is counter-intuitive as far as SQL goes!?
