Learning FreeSWITCH - Can't call into test installation
by William Colls 23 Jan '16

23 Jan '16

I am new to freeSWITCH, and working trough the examples from the FreeSWITCH (1.2) Book. I have the system built, and running, and everything looks OK. The system registers with my VoIP provider (voip.ms), an IP phone registers with FreeSWITCH, and I can call out to the POTS. However, when I try to call into the IP phone, I can see the incoming call information at fs_cli, but it instantly hangs up, and never goes through to the intended destination set up in dialplan/public/01_voipms.xml. The message that I get is [NOTICE] switch_core_state_machine.c:315 sofia/external/613XXXXXXX(a)158.85.70.XXX has executed the last dialplan instruction, hanging up Appreciate any pointers as to what/where I should be looking for the problem. Thanks for your time. William.

Identify billable calls
by John Nash 23 Jan '16

23 Jan '16

I am using bridge application to connect to carrier gateways and using CDR csv module for billing. In my logic I am only billing calls which have billsec>0 now I wonder if this is correct way to find what calls are connected I mean may be some calls I am ignoring which were connected for less than 1 second?..Is that possible?...what is the sure shot way to filter connected calls?

mod_callCenter scalability
by Varsha Agarwal 22 Jan '16

22 Jan '16

Hi, Does anyone have any data on how mod_callCenter scales? How many queues, concurrent calls, number of agents can be supported on one instance of FreeSwitch? I looked through the whole documentation but did not find any data. Thanks, Varsha

Linux clocksource TSC vs HPET
by François 22 Jan '16

22 Jan '16

Hi all, I'm trying to find a solution for an "RT throttling" issue under relatively high load (20cps) on linux 3.10 and CPU Xeon E5-1650v2 (6cores). A similar jira ticket FS-8620 has a recommendation to set the clocksource to "hpet": echo hpet > /sys/devices/system/clocksource/clocksource0/current_clocksource I read somewhere that the default clocksource (TSC) is lighter in CPU usage because it only requires reading a register that is synchronized across all cores... Considering FreeSWITCH needs: -> Is HPET recommended over the default "TSC" clock? -> Does a change in clocksource have immediate effects or does it require an FS restart/reboot? -> Also, is it recommended to disable RT-throttling to resolve these types of issues? echo -1 >/proc/sys/kernel/sched_rt_runtime_us echo -1 >/proc/sys/kernel/sched_rt_period_us Thanks, François.

Possible performance problem
by Jose Fco. Irles Durá 22 Jan '16

22 Jan '16

Hi, I have a FreeSWITCH (1.4.26) for click2call call center application in production. Some times, I have detected some delay on bridge operations (captured with tcpdump): 1. originate call to softphone and softphone answers 2. deflect call 3. bridge to a gateway in the step 3, some times (I suspect in peak hours) when the FreeSWITCH receives de 200 OK from the upstream gateway when de called party answers, it delays until 3 seconds to send the 200 OK to the softphone leg. How I can debug if it is a performance problem? The system is a lxc container on top of drbd disk. On peak hours the system has around 60 concurrent calls The calls are recorded in ram disk The FreeSWITCH is connected to localhost postgresql database for its core db. Best regards

the unit for answered_time
by ik 22 Jan '16

22 Jan '16

Hello, I require to calculate on hangup the duration of a call regardless of the CDR, and do some logic if it's above a range. I'm placing at the api_hangup_hook a cli parameters that one of them is answered_time. I need the data in minutes unit, and the data seems to be a timestamp in microseconds, but converting it to seconds (e.g. answered_time / 1000000) provides me a very low range of number, sometimes even less then a millisecond. I can't seems to find at the documentation what is the unit for the answered_time in order to properly convert it to my requirements. I'm also missing the place at the source code where the data is set to the variable (here is the grep result (at the src directory): grep answered_time ./* -R ./mod/event_handlers/mod_cdr_mongodb/mod_cdr_mongodb.c: bson_append_long(&cdr, "answered_time", caller_profile->times->answered); ./mod/languages/mod_managed/managed/ChannelVariables.cs: const string answered_time = "answered_time"; ./mod/languages/mod_managed/managed/ChannelVariables.cs: get { return readUsecsDateTime(answered_time); } ./switch_caller.c: if (!strcasecmp(name, "answered_time")) { ./switch_core_session.c: } else if (!strcmp(tag3->name, "answered_time")) { ./switch_ivr.c: if (!(time_tag = switch_xml_add_child_d(x_times, "answered_time", t_off++))) { ./switch_ivr.c: cJSON_AddItemToObject(j_times, "answered_time", cJSON_CreateString(tmp)); So what am I missing here? Thank you Ido

mod_verto: Invalid Method, Missing Method or Permission Denied / Error code": -32601
by Emrah 22 Jan '16

22 Jan '16

Hi all, Looked too easy to be true… I’m all set up with FS and the Verto demo. I use commercial certificates, the cA is already in my distrib, and everything seemed to work well. I can log in from the Verto page… Except when I attempt to make a call, it miserably fails with error code": -32601. I did my Google homework with no luck. Some stuff seem to point to the CA needing to be imported, but not sure where I could have gone wrong there. There is hardly any verbose… But a debug output is here: http://dmn.io/fs-verto-error.txt The error message is: Invalid Method, Missing Method or Permission Denied I’m not sure what to investigate here. Your suggestions are welcome! Running FreeSWITCH Version 1.6.5-11-d5520a6~64bit Thanks

Is there some setting that stops configuraton from being loaded from sofia.conf.xml?
by vfclists . 22 Jan '16

22 Jan '16

I am experiencing a strange issue on my system. It seems that configurations in sofia.conf.xml will not load correctly. It is a configuration that contains the entirety of internal.xml and external.xml in the sofia.conf.xml file, bypassing the files on the sip_profiles/external and for some reason it wasn't loading. However when I copy the profile sections for the internal and external profiles into the sip_profiles directory, it works normally. Is there some setting that can cause this? -- Frank Church ======================= http://devblog.brahmancreations.com
