07 Mar '12

FreeSwitch is new for me. I want to make my own small application in lua and connect to mysql DB. Could anyone please suggest me how to start programming in Lua ? I am reading below thread for Lua programming. I want to boost it up with small program so that my confidence will increase. http://www.lua.org/pil/index.html Any book for programming in Lua for freeswitch -- Thanks and regards Virendra Bhati +91-8885268942 Software Engineer E-mail-: virbhati(a)gmail.com Skype id:- virbhati2 Hyderabad(India)

answer when agent connects in mod_callcenter
by Anita Hall 07 Mar '12

07 Mar '12

Hi! I tried mod_callcenter and I must say it is an amazing piece of work by Marc Olivier Chouinard! We had built something like this over ESL but nothing beats a loadable module :) The tricky question is how do I configure it so that the caller is answered only after an agent is connected? By default, the call is answered and moh is played. Is it even possible or do I have to look inside mod_callcenter? If that, exactly where does a module answer a call ? Thanks. regards, Anita

Any alternative to repetitive lua session:ready() calls?
by Adam Kelloway 07 Mar '12

07 Mar '12

Hi there, If I am running a lua script during a call, and the call terminates (caller hangs up, for instance), the lua script continues to execute while the session has already been terminated. This causes ERR entries in the freeswitch log, which I would like to try and minimize. The only way I can see doing this is to frequently call session:ready() before doing anything that could break the script. Is there a better way to exit a script cleanly, without having to add X number of session:ready() calls scattered about the script? Currently, I only call it once (at the beginning of the script). I tried using the hangup hook, but I'm not sure how I can get it to immediately exit the script. Thanks, Adam

SHUTDOWN event
by Drazen Blanusa 07 Mar '12

07 Mar '12

Hello, I'm using Java ESL library for communicating with FreeSWITCH. If i subscribe for events, using method setEventSubscriptions, and define list of events, in case of SHUTDOWN event, FreeSWITCH says: [NOTICE] switch_event.c:1889 Event Binding deleted for mod_local_stream:SHUTDOWN If I set subscription for ALL events, than it's working fine. NOTE: it happens only in case of SHUTDOWN event, other events works fine. Anybody knows where is the problem? I've checked ESL subscription string, and it seems to be ok, so I guess it is problem on FreeSWITCH side. Best regards, Drazen

How to Blind Transfer After a Conference
by Bob McCarthy 07 Mar '12

07 Mar '12

I have some customers that are using SLA but want to Blind transfer the call after the supervisor drops out of the conference. (2 legs left in call) in Asterisk I would use the bridge command which would pull the channels out of the conference and bridge them together. I tried to do the same thing in Freeswitch from a lua script but I get the error: [ERR} switch_cpp.cpp:1277 Channels not ready I parsed the channel names out of the Conference list: Conference 8b09249a-67df-11e1-899d-2dc9f6a91475 (2 members rate: 16000) 95;sofia/internal/sip:CO999x1001.3@192.168.57.102;8b0b8262-67df-11e1-89a5-2dc9f6a91475;Outbound Call;303-444-5555;hear|speak|talking|floor;0;0;0;200 94;sofia/internal/101(a)192.168.57.31;8b09249a-67df-11e1-899d-2dc9f6a91475;911 Trunk 01;303-444-5555;hear|speak;0;0;0;200 Some debug output to make sure I am using the correct channel names: channelarray[1]=sofia/internal/sip:CO999x1001.3@192.168.57.102 channelarray[2]=sofia/internal/101(a)192.168.57.31 Here is the relevant script commands session1 = freeswitch.Session(channelarray[1]); session1 = freeswitch.Session(channelarray[1]); freeswitch.bridge(session1, session2);

ENUM
by Miha Zoubek 07 Mar '12

07 Mar '12

Hi, I am having users as registered 018100125.fs1.adsijiiojas.com. In dial plan I am checking if numbers that is registered on FS is ported or not. If it is ported that ${enum_auto_route} if not that do like this: <anti-action application="bridge" data="sofia/internal/${sip_redirect_contact_user_0}.fs_kabelvoip1%fs_kabelvoip1.f…"/> Enum: <action application="bridge" data="{origination_callee_id_name='${sip_req_user}'}${enum_auto_route}"/> I am doing this beacuse I would like to have number that enum return in my billing but the call should be made locally like for internal calls without enum. Is there any options to get that kind of behaviour (in cdr to have enum number but call is made like for internal calls)? Thanks! Miha

Re: [Freeswitch-users] Freeswitch as a register server
by Mike Patterson 07 Mar '12

07 Mar '12

I am trying to find out if I could use freeswitch as a register server. Freeswitch would actually be acting more like an SBC. I would like to provide my users a domain or IP address to register with and have Freeswitch pass the registration request to my soft switch. I read on the Freeswitch wiki that there is some SBC functionality but I did not find anything specific to my needs. I would appreciate any suggestions or help.
