Thanks a lot. This helps and solve my issues. Thank you again. --- original message --- From: "Hector Geraldino" <Hector.Geraldino(a)ip-soft.net> Subject: Re: [Freeswitch-users] event socket Date: 26th October 2011 Time: 8:55:00 pm Hi, The best source is the Mod_event_socket page on the wiki. http://wiki.freeswitch.org/wiki/Event_Socket http://wiki.freeswitch.org/wiki/Event_Socket_Outbound You can answer a call by using a socket inbound connection to freeswitch, and you don't need to write any special instructions on the dialplan to do so, just listen for events and send api commands. But in my particular experience, if you want to control an incoming call (a call that hits an extension managed by freeswitch) you'll be better served by using a socket outbound connection. Off course this is from a design perspective, not because there are limitations when using an inbound connection. Think about a socket outbound connection as a substitution of part of your dialplan. You take complete control over the incoming call, and you can answer it, play messages, capture dtmf tones, bridge it to another extension, etc. in a more cleaner way. The socket inbound connection in my experience is better suited for situations where you need to create (and control) a new call from freeswitch to another extension, either controlled by freeswitch or another platform through a gateway. A simple use case scenario: an IVR app that bridges an incoming call to another leg: 1) PSTN -> FS -> Outbound socket app (C#) 2) C# app answers the call, plays a message and wait for DTMF tones 3) User presses 1 on the dialpad, an event is sent to the C# app 4) The C# app creates a new inbound connection to FS, and using this new connection: a) Originates a call to another extension (leg B) b) bridge the two calls, using uuid_bridge In resume what I'm trying to say is: use outbound mode to control incoming calls as a way to replace/enhance the actions you can execute in a diaplan, and use inbound mode when you want freeswitch to make new calls, check status, etc. Again, you can use the inbound mode to perform the same tasks as with outbound, this is just a guideline based on my experience.

Could you please answer couple of questions, 1. Can an external application in inbound mode can answer inbound calls. For example extension 200 dials 9. Is it possible to answer this call by an external application (inbound mode) ? If it is possible what is the dial plan entry for this ? I read event socket inbound and outbound mode and I'm under the impression that I can't use an external application in inbound mode to answer calls. 2. Could you please direct me to a source where I can find all supported features/functionality in event socket inbound and outbound mode. Thank you, From: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Hector Geraldino Sent: 25 October 2011 20:19 To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] event socket I just figured out something when reading your code. By looking at your dialplan it looks like you're willing to take control over the incoming calls in your application by using the 'socket outbound' connection mode. In this case your application MUST act as a server and listen for socket connections on the designated port (you need a Server Socket class or its equivalent in .NET). However according to your dialplan it looks like you're trying to bind the incoming call back to freeswitch, using the default port that FS uses for inbound connections (8021) - please correct me if I'm wrong. If you actually want to give the control of the incoming call to your application, you should use a different port, or change the FS default port on the configuration. I don't know if the eslConnection class in .NET allows you to listen for incoming socket connection, but it looks to me more like a socket client. Probably you should double check the Mod_event_socket documentation on the wiki to get more info about the .NET client library, and have a better understanding of the inbound/outbound connection modes. In the outbound mode you need to listen for new connections from your application, and you configure this mode by modifying the dialplan in the way you've done. In the inbound mode you can have a regular dialplan, and receive events for the calls that are handled by freeswitch dialplans.

incomplete metaswitch voicemail configuration
by Dean Johnson 26 Oct '11

26 Oct '11

When the Metaswitch tries to forward a call to the freeswitch, it gets back a 480. and the freeswitch log shows that it breaks off its side. We have been following the http://wiki.freeswitch.org/wiki/FreeSwitch_MetaSwitch_HowTo with the idea of setting up freeswitch in our test lab to be a voicemail application server for our Metaswitch 2510. We successfully compiled, installed and are running freeswitch on Centos6. Voiper can call and leave voicemail, as well as go retreive the voicemail. The Metaswitch 2510 and freeswitch "see" each other without error messages. We are new to freeswitch and are wondering if we have left out some configuration that assigns freeswitch a correct telephone number or range of numbers that it can service for voicemail. What information can I provide so I can learn what I have omitted? ______________________________________ Dean Johnson

Re: [Freeswitch-users] Italian voice files
by Giovanni Maruzzelli 26 Oct '11

26 Oct '11

Hello Iesoua, I believe it will cost around 2500$ (roughly) to have it professionally produced, recorded, equalized, etc from GM Voices. That's an order of magnitude, you better check for actual prices (I'm sure they'll apply a discount if they know it will be put in standard FS distribution, because it will bring them more business for additional customized prompts in the future). Would be great if you can then put it in public domain and add it to the standard FreeSWITCH distribution. Michael Collins (mcollins, mercutioviz on irc) can give you all details about how to interact with GM Voices (or your preferred prompt provider) and how to put the collection into FreeSWITCH distribution. -giovanni On Wed, Oct 26, 2011 at 11:34 AM, iesoua - pms italia <iesoua.semeco(a)pmsitalia.it> wrote: > Hello Giovanni, > > we're interesting in buying the italian voice pack for freeswitch, could you > please let me know the price for the package? > > > Thank you > > -- > Iesoua Semeco > ICT Department > @mail: iesoua.semeco(a)pmsitalia.it > Mobile: +39 333 2525230 > Office: +39 02 87241129 > ____________________________ > PMS Italia srl > Viale Enrico Forlanini, 15 > 20134 MILANO MI - Italy > Tel: +39 02 872411 > Fax: +39 02 45479990 > ____________________________ > > > > Il 25/10/2011 19:26, Giovanni Maruzzelli ha scritto: >> >> mmmmmh, I don't think they exists. >> >> I had almost convinced a customer to order the entire set, but then he >> ended up using completely custom messages (and a small number of >> them)... too bad :(. >> >> As soon as I'll have some customer paying for it I'll order the set >> from GM voices... >> >> Let me know how it goes. >> >> _giovanni >> >> On Tue, Oct 25, 2011 at 6:23 PM, Michael Collins<msc(a)freeswitch.org> >> wrote: >>> >>> Ciao! >>> I am looking for an Italian set of sound files for FreeSWITCH.

How to know who is calling me...
by Francisco Javier Cintrón Olguín 26 Oct '11

26 Oct '11

Hello from Guadalajara, México. :) For the last month I have been reading the fs book and playing with fs. I am pretty conviced that It would be perfect as my soho office. I have this configuration: 4 normal internal phones. 2 pots lines. to interface freeswitch with these devices I purchased a CISCO SPA8800. This unit has 8 ports: 4 for normal phones. 4 for pots lines. I also purchased a cheap IP phone: linksys SPA921. With the help of fs wiki site I got how to configure the SPA8800. The only thing I don't know is how to show in the LCD display of the SPA921 who is calling or the number from which is the call. Thanks in advance for your kind help.
