Language Preference and LUASQL leak??
by D Al 11 Jul '10

11 Jul '10

The Wiki and comments on this list talk highly of Lua as the "preferred" language to use with FS, although JavaScript seems to be very active. The Wiki also mentions a serious memory leak when using the LUASQL. Is that still the case? And if so, is there a way to use LUA and access a MYSQL database that makes sense? Thanks

Spoken name recognition
by Tom C 11 Jul '10

11 Jul '10

I couldn’t find anything about this in the mailing list archives; everything was about full speech recognition and transcription of voicemail. Perhaps I just don’t know the correct term to search for. I want to set up directory where the caller says the name of the person, and the call is forwarded to that person. E.g. Freeswitch: “Please say the name of the person you are looking for” Caller: “Megan Fox” Freeswitch: “Morgan Freeman. Is this correct?” Caller: “No” Freeswitch: “Please say the name of the person you are looking for” Caller: “Megan Fox” Freeswitch: “Doctor Flox. Is this correct?” Caller: “No” Freeswitch: “Please say the name of the person you are looking for” Caller: “Katy Perry” Freeswitch: “Katy Perry. Is this correct?” Caller: “YES!!!!!!” Freeswitch: “Connecting….” This shouldn’t require as elaborate a speech recognition system, since the “dictionary” will be very small. Should I just look at the Vestec adapter? Or is there something smaller and cheaper available?

originate call hangup signal
by Tony Tin 10 Jul '10

Hi, When I use OpenZAP channel to originate a call, after the called party hangup the phone. It takes freeswitch around 40 seconds to catch the hangup signal and stop the dial plan. I'm wondering whether there is a way to shorten that duration. Thanks. Regards, Tony

mod_nibblebill and mod_xml_cdr problem
by Sergey Okhapkin 10 Jul '10

10 Jul '10

When customer's balance falls below nobal_amt and mod_nibblebill transfers the call to nobal_action (which just does hangup), mod_xml_cdr doesn't send all leg a channel variables to the url (<param name="log-b-leg" value="false"/>). More precisely, it sends only channel variables set by FS, but no variables set by dialplan on leg a. I suspect it sends only leg b variables. Am I right?

Freeswitch - wholesale setup
by Voip Newbie 09 Jul '10

09 Jul '10

Dear List, I am new to voip and to freeswitch and I am trying to learn how to setup a wholesale scenario using FreeSwitch. I have very little experience in running wholesale voip business on voipswitch. I know all or most of the answers to my questions are already either in wiki or in list archive, and I am really sorry to email the list asking for help but with the little knowledge I have its way over my head and I failed to compile the information in right way to achieve any result, please forgive me if these questions bother any of you at all. Here is what I wish to achieve with FreeSwitch: 1) Setup username/password less accounts for customers with IP authentication. One customer can have multiple IPs. Customer can send traffic using SIP or H323 protocol. A prefix will be assigned to customer for sending traffic. Eg. 1234 + Country code + Area code + Number. 2) Customer can be post paid or per paid, so need to disable customer's ability to call when assigned credit limit is reached. 3) Setup providers (Gateways) which do not provide username/password for authentication and do not require FreeSwitch to register with them, FreeSwitch IP will be allowed to send traffic directly with a 3-4 digit prefix. Provider can be on H323 or SIP either and can have multiple IPs (1 primary and other for fail-over) 4) Customer and providers need access to CDR. So we need to configure Freeswitch the way that it can store CDRs in MySQL database, that database can be accessed by a web application to show CDR on web. *Hardware and OS info:* CentOS 5.4 (Linux 2.6.18-164.15.1.el5PAE on i686) Intel(R) Xeon(R) CPU E5420 @ 2.50GHz, 4 cores 4 GB RAM. 1 GIGABIT NIC with a Public IP address *Progress so far:* 1) FreeSwitch installed with installation procedure at FreeSwitch Wiki ( http://wiki.freeswitch.org/wiki/Installation_Guide#Download_Source_Tarball) 2) Registered and called already created extensions (1001,1002) from x-lite, called echo extensions and everything worked fine. *Questions:* 1) I can see there are 2 H323 mods available for FreeSwitch, which one is better to use in production. a) http://wiki.freeswitch.org/wiki/FreeSwitch_H323 b) http://wiki.freeswitch.org/wiki/Mod_h323 2) How and where (location in freeswitch conf) can I create customers, add IP addresses to authorize without username and password, assign a prefix to the customer? An example would be nice. 3) How and where (location in freeswitch conf) I can create gateways. An example would be nice. 4) Where to create dialplan to route customer calls to provider. An example would be nice. 5) How to manage credit assigned to customers, and how to bill the calls? 6) How to configure Freeswitch so that it can dump CDRs to a mysql database. 7) According to FreeSwitch feature list, it supports g723 and g729 in pass-througe mode, so this means if both customer and providers support g729 & g723, calls will pass? 8) Is there any limit on g729 and g723 calls in pass-through mood? 9) Approx how many concurrent calls can FreeSwitch support in H323 and in SIP based on the hardware info given above. Any pointers, help, links, examples will be highly appreciated. Thanks in advance. -Eric

High cpu usage on EC2 Centos 5.4
by paul gore 09 Jul '10

09 Jul '10

Hello there, Seems like I hit another problem running FS 1.0.6 on EC2 - CPU usage by FS alone hits 65% for just one call! Here's output from top command: 26348 root 15 0 418m 42m 8024 S 65.8 0.6 808:37.18 freeswitch We use Rightscale image Centos 5.4 EBS and m1.large instance type. What can be possible reasons for that? I have never seen FS using more than 10% CPU for 50 calls on a regular box under Centos 5.2, we have version FS 1.0.5 there.

Freeswitch+Siemens A580IP
by Nick G 09 Jul '10

09 Jul '10

Greetings. I have a bit of a problem with placing outgoing calls with my Siemens on my freeswitch PBX, which seems to have to do with the way it handles sending a ring signal to someone on the call. Instead of the method used by other PBX's, it seems to send audio back, rather than being content to let my sip device take care of sending me the ring signal. Consequently, it has a hard time negotiating media when someone actually picks up the call. Can I fix this? If so, how? Thanks, Nick
