Performance testing

Hi all, I'm testing Freeswitch using ESL interface, recording and SIP UDP Calls at a rate of around 5 CPS. Freeswitch receives ESL requests and proceeds to send call to PSTN Emulator, once call is answered I start recording. I have noticed around 40% CPU utilization when recording is not enabled and ~60%+ CPU when recording is. I created/mount a volume specifically to store the recording files. (ext4) *Server specifications:* EC2 server (t2.medium) 2 vCPUs, 2.5 GHz, Intel Xeon Family, 4 GiB memory. FreeSWITCH (Version 1.6.9 -16-d574870 64bit) I followed instructions at: https://wiki.freeswitch.org/wiki/Performance_testing_and_configurations *[Questions]* a) How to strip down Freeswitch and remove non-used modules?

uuid_broadcast att_xfer + ringback
by Igor Olhovskiy 06 Oct '16

06 Oct '16

Hi! I’m trying to make an att_xfer via uui_broadcast. Scenario is I have a call between internal (A) and external (B) profile. On both channels set variables ringback=local_stream://moh transfer_ringback=local_stream://moh hold_music=local_stream://moh I can confirm them via cli with uuid_getvar I’m trying to transfer call from A to C. (At the end - connect B and C) Than I’m giving command via event socket uuid_broadcast B_CALL_UUID attxfer::sofia/gateway/XXX/NUMBER bleg (Why I’m not giving uuid_broadcast to A_CALL_UUID - cause I’m already have B_CALL_UUID and finding out A_CALL_UUID is an additional step, that I want to avoid) But I don’t get ringback music in this channel, only silence. What I’m missing? -- Best regards, Igor

ESL event on OPTIONS fail
by Tanguy 05 Oct '16

05 Oct '16

Hello I would like to real-time monitor network reliability for each extensions on multiples freeswitch servers ( no shared core or sofia database ). Using ESL i can monitor users registrations and network lost ( by catching unregister event thanks to all-reg-options-ping ) But is it possible to make ESL event for each OPTION packet without reply or even better make an event if the latency is above a predefined threshold ? Thanks

Fax / voice splitting question
by Magnus Kelly 04 Oct '16

04 Oct '16

Hello all , Please could someone share if its possible to split voice and fax calls, e.g. numbers that are used to also receive fax¹s to be forwarded by SIP to FreeSwitch in order to answer calls and then somehow automatically determine between voice and fax calls and onward route to either fax extension or to a hunt group to find a person? I was thinking of looking for T.38 in the SDP, but then understood that this only appears in the actual fax transaction and thus bit late in the setup to determine routing. Appreciate any tips if others have successfully found solutions to this call case. Thanks Magnus

Hi, All! I founded some strange thing: when call is initiated by freedm module I haven`t see any working execute_on_ring fction on B-leg. I`m doing somtheing like: <action application="export" data="nolocal:execute_on_ring=lua incoming_event_fire.lua"/> But it doesn`t start. But near wrote: <action application="export" data="nolocal:execute_on_answer_1=lua answer_event.lua"/> <action application="export" data="nolocal:execute_on_answer_2=lua answer_event_fire.lua"/> ...starting successfully.
