Implementing telecom module with FreeSwitch
by Manish Talwar 03 Mar '15

03 Mar '15

Hi, We have successfully implemented FreeSwitch with our IVR application using httapi module and its running fine now. After implementing IVR application, we are looking for implementing telecom module with FreeSwitch now. We have a plan to activating a set of 20 number, for this we have a "sangoma wanpipe driver" on the server and some kernel modules loaded that will communicate with a Sangoma A104 card installed there. Incoming Qatari +974 phone calls will arrive and will be translated on our server to SIP traffic for our IVR system to process. One or more of the numbers will be reserved as office numbers. I have looked into telecom service of FreeSwitch and found freeTDM module for implementing telecom with FreeSwitch. Can we achieve this telecom implementation by freeTDM module of FreeSwitch? If yes, then please help me for implementing telecom module with FreeSwitch with freeTDM and let me know all details about it. Also, please let me know any other useful information regarding this module. Thanks, Regards, Manish Talwar

mod_callcenter not updating
by Ali Jibran 03 Mar '15

03 Mar '15

I am using FreeSWITCH (Version 1.5.15b git 556cb5c 2015-02-05 00:55:29Z 64bit). For some reason "reload mod_callcenter" doesn't update when I edit callcenter.conf.xml. It only updates agents being added but the ones that have been removed do not go away. Is it some bug?

Mod_shout libfacc support
by Eloy Coto Pereiro 02 Mar '15

02 Mar '15

Hi, I'm trying to play a libfaac[0] files into my Freeswitch, but I can't get it working. Play mp3 files work ok, but encoding with libfacc doesn't work. This is my config in mod_shout: <action application="playback" data="shout://localhost/suite.mp4"/> In the other hand, I tried mod_vlc to play mp4 files, but It didn't work too. I compiled from sources, and tried with debian backports too. <action application="playback" data="vlc://http://localhost/suite.m4a"/> In both cases http request work, reply 200 ok and with data. Play mp3 with both modules work ok. In the other hand, mod_shout and mod_vlc are loaded correctly, and module_exists return always True. Any idea? Is libfaac supported?

supporting multiple dtmf protocols
by ik 01 Mar '15

01 Mar '15

Hello, I have the misfortune of forced to use a telco named Bezeq - the biggest telco in Israel. The SIP trunk they provide is very problematic. The one that I cannot overcome is that sometimes doing the call, it switches DTMF between Inband and rfc2833, and sometimes the whole DTMF sending is either inband or rfc2833 doing the entire call. I cannot make them to be more stable in this matter (I have tried talking with them), and I cannot replace them (I have tried to do so as well). How can I deal with such mess ? Thanks, Ido

originating a call from event socket
by Royce Mitchell III 01 Mar '15

01 Mar '15

I need to initiate a call on an agent's behalf, but I can't seem to get it to work. This is the closest I've gotten ( 7777 puts agent back in the call-queue ) uuid_setvar <agent-uuid> transfer_after_bridge 7777 uuid_transfer <agent-uuid> <pstn-number> I have 2 problems: 1) the transfer_after_bridge isn't happening, or it's not going to the right place 2) I have to wait forever to get a uuid to control that call. I want to be able to allocate a uuid for the outbound leg before I initiate the call, but I can't figure out the syntax to make it work. I've tried this, but I get a fast busy: uuid_transfer <agent-uuid> {origination_uuid=<new-uuid>}<pstn-number> I've also tried this and it doesn't work either: originate {origination_uuid=<new-uuid>}sofia/external/<pstn-number> &bridge(<agent-extension>) Please help, thanks Royce Mitchell, IT Consultant ITAS Solutions royce3(a)itas-solutions.com

mod_callcenter - cc_warning_tone not working
by bedgar＠vseinc.com 27 Feb '15

27 Feb '15

Hello Experts, I have been working on setting up a call center in FS and am having a problem with the warning tone notification. It does not play any tones before the caller is bridged to the agent. I am using the latest stable build for 1.2 and I am using the example in the wiki: https://wiki.freeswitch.org/wiki/Mod_callcenter#uuid-standby Snippet: <extension> <condition field="destination_number" expression="^(4099)$"> <action application="set" data="transfer_after_bridge=4099"/>  <action application="set" data="res=${callcenter_config(agent set uuid ${caller_id_number}@${domain_name} '${uuid}')}" /> <action application="set" data="res=${callcenter_config(agent set type ${caller_id_number}@${domain_name} 'uuid-standby')}" /> <action application="set" data="res=${callcenter_config(agent set status ${caller_id_number}@${domain_name} 'Available (On Demand)')}" /> <action application="set" data="res=${callcenter_config(agent set state ${caller_id_number}@${domain_name} 'Waiting')}" /> <action application="set" data="cc_warning_tone=tone_stream://%(200,0,500,600,700)"/> <action application="answer" /> <action application="playback" data="$${hold_music}"/> </condition> </extension> I have tried changing the tone values to see if making it repeat or play longer would produce a positive result. No dice... On a second note, is there a way to play a file to the agent before the call is bridged? My call center services multiple brands and would like to have the agent greet the caller appropriately. Thank you, Brian Edgar

Freeswitch 1.4.15 and a sudden jump in CPU usage
by Ali Pey 27 Feb '15

27 Feb '15

Hello, Normally our CPU usage during peak hours are less than %10; however, time to time, freeswitch uses more than %95 of the CPU and it stays there forever. The only way to get it back to normal is to restart freeswitch service. During the high CPU usage, freeswitch continues to operate but very very slow. If I lower the traffic quite a bit, the CPU comes down, but adding back the traffic, the CPU usage goes right back up. After freeswitch restart, it becomes normal again with the same traffic. Any ideas or suggestions? Much appreciated. Thanks, Ali Pey
