Hi I used freeswitch on centos 6 . I downloaded freeswitch from “git clone https://freeswitch.org/stash/scm/fs/freeswitch.git And configure properly without errors Then I try to configure mod_verto , https://freeswitch.org/confluence/display/FREESWITCH/mod_verto First I compile the module and then I did configurations from mentioned link below, But I couldn’t create ssl certificate from that instructions Then I used following command to create the certificate and key openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /usr/local/freeswitch/certs/wss.key -out /usr/local/freeswitch/certs/wss.crt cat wss.crt wss.key > /usr/local/freeswitch/certs/wss.pem cat wss.crt > /usr/local/freeswitch/tls/dtls-srtp.crt then I changed ssl.conf file (/etc/httpd/conf.d/ssl.conf) as follows ServerName myserverip:443 SSLEngine on SSLCertificateFile /usr/local/freeswitch/certs/wss.crt SSLCertificateKeyFile /usr/local/freeswitch/certs/wss.key Then restarted httpd server Get the firefox and put https:// myserverip/verto Ask certificate and after add the certificate Loaded login page but can’t log in freeswitch console print following message 2014-12-02 18:11:40.150201 [INFO] mod_verto.c:3688 192.168.1.195:4870 Client Connect. 2014-12-02 18:11:40.150201 [INFO] mod_verto.c:1827 192.168.1.195:4870 Starting client thread. 2014-12-02 18:11:41.169676 [DEBUG] mod_verto.c:1739 192.168.1.195:4870 WS SETUP FAILED [] 2014-12-02 18:11:41.169676 [INFO] mod_verto.c:1853 192.168.1.195:4870 Ending client thread. 2014-12-02 18:11:41.169676 [INFO] mod_verto.c:1860 192.168.1.195:4870 Thread ended Kindly help me to configure this thankyou ach

Questions before starting new install
by Allison Walters 02 Dec '14

02 Dec '14

We're wanting to replace our current freeswitch server (it's fairly old), and I have a few things I'm curious about before I start trying to build the new one. I inherited the current one and am relatively unfamiliar to all of this, so I appreciate your patience. 1. I was told by the consultant that set up the current box that freeswitch doesn't play well with fusionpbx or really any of the GUI's - there have been instances (and indeed one happened a couple of months ago while I was here) of the config files getting randomly overwritten with old settings, which supposedly is the fault of trying to run fusion. Also I was told it doesn't provide nice clean XML, etc... I was strongly encouraged to go with no GUI. If it were just me, I'd be okay with that, but we have a couple of other people who might be helping to maintain the server and they're far more comfortable with GUIs. Has anyone else had any of these issues, and/or have any recommendations on the subject? 2. I'm trying to install on Ubuntu. When I go to the wiki, I get this page: https://freeswitch.org/confluence/display/FREESWITCH/Linux , which just gives an apt-get line for Ubuntu. However, that line just seems to have pre-reqs and not freeswitch itself. Anyone know where I could find current Ubuntu instructions? I googled but the most recent pages I could find were from 2012, and most were from 2011. Is that the most up to date? 3. Are there any guidelines for migration from an old server running an old version to a new server with a current version?

We want to use dialplan python script. Script working but call setup is lasting too long ( <10sec to >40sec when 60 concurent calls on switch) Script just route call from user to gateway. I've not a lot of experience in FS and programming, so I need your help. Ps I'm not good in English, excuse me. Code part sessionData = 'sofia/gateway/gwname/dest' new_session = Session(sessionData,session) if new_session.ready(): bridge(session,new_session) if new_session.ready(): new_session.hangup() hcause = new_session.hangupCause() My native language is

Verto™ Not just for call signaling
by Ken Rice 01 Dec '14

01 Dec '14

New Post on freeswitch.org from anthm check it out at http://ift.tt/1vL90Zr Verto™ Not just for call signaling Verto is not only focused on call signaling; There are a few other key components that are important to understand. One key component of Verto is event channels. Event channels are bi-directional subscription-based logical data channels used to relay information in an organized fashion. This is a low level building block for many features. For instance, call or chat presence. Event channels can be subscribed to from JS and granular permissions may be set from FS on-the-fly or ahead of time. Modules inside FreeSWITCH fire json events and every connection who has a subscription will get a copy of the data allowing action to be taken. At the same time each browser connection is able to send a request back to the server on a particular event channel which can trigger action varying from sending more events, a full sync of saved data or even pushing the events into another event bus to send to another external application. Our demo site http://ift.tt/12g7Iff and call 3500 you can see an example of the data synchronization functionality as it will generate events that sync and update in real time a data structure in FreeSWITCH and one in the page of anyone subscribed. Because 3500 is a conference, the conference module will grant you access to the data about who else is called into the conference. It sends an event scoped to the exact uuid of the connection of the calling verto client. This event says that there is an available data synchronization for the particular conference. Using the data from this event, you can initialize an object that uses event channels to subscribe to the conference data and request a full sync and then keeps the object in sync with update events as long as you are on the call. This allows a table to be drawn in real time reflecting the changes going on in the conference. When you hangup, it sends a similar event telling you that you should unregister from this service and removes your permission. If you wanted, you could allow permissions to one or all conference data from your FS config and use verto to connect and provide info about who’s in the conference even when you are not connected directly. Another important feature of the module is the ability to communicate with FreeSWITCH and invent your own api modules. The lower level json-rpc in FS contains 2 important commands, fsapi and jsapi. fsapi allows you to execute any FreeSWITCH FSAPI command (basically all the commands you can type at the cli) This is set on a per command permission basis and is of course best used with security in mind. The other command, jsapi, is used to interface with a new type of module interface in FreeSWITCH called the JSON API Interface (JSONAPI) This interface is similar to FSAPI only its designed with a JSON in JSON out structure. One could write a C module defining a series of JSONAPI designed to allow your html5 application to communicate directly with your module in the same fashion that mod_verto does. This allows mod_verto to host the server logic and just pass commands up to your module and communicate in basic json exchanges. There some examples in FreeSWITCH now that you can test from your cli There is a FSAPI command called json that just assumes the input is a chunk of json and passes it right into JSONAPI then gets the results and converts it back to text so you can see it on the screen. Paste this command into your terminal: json {“command”: “status”, “format”: “pretty”, “data”: {}} Had it been over jsonrpc it would have been sent with method of jsapi and the json below would have been the params element: { “jsonrpc”: “2.0”, “method”: “jsapi”, “params”:{“command”: “status”, “format”: “pretty”, “data”: {}} “id”: 2 }

Donate creation of mod_gearman module
by Mateusz Bartczak 01 Dec '14

01 Dec '14

Hi I’m looking for experienced FreeSWITCH developer to build new module which will allow to send FS events using Gearman library. Something like existing mod_zmq module, but for other protocol. Additionally module should support of RPC calls from Gearman clients and invoke them as API (blocking) and BGAPI (non-blocking) commands inside FS. I have detailed specification of needed functionalities. Looking for someone ready to start promptly and make it fast. If someone from core FS dev team will respond, then I can declare to push back this module as open source available for all of the community Anybody interested please PM me: netcentrica(a)gmail.com

echo cancellation and mod_conference
by covici＠ccs.covici.com 01 Dec '14

01 Dec '14

Hi. I have some sip callers who call in on what are apparently bad lines and get echo when calling into conferences -- not freeswitch ones yet. So, I am wondering in mod_conference is there any attempt to do echo cancellation, if so I will try to have them call into an fs one instead. Its intermittent, so I wanted to find out first before I test. Thanks in advance for any suggestions. -- Your life is like a penny. You're going to lose it. The question is: How do you spend it?

mod_verto behind NAT
by Ciprian Dosoftei 01 Dec '14

01 Dec '14

Hi, I am dealing with a NAT situation related to mod_verto. The switch is hosted in EC2 and the configuration works great with mod_sofia (both for receiving calls from our SIP providers and via webRTC clients). However, the counterpart configuration for mod_verto fails to expose the external IP address in the SDP. Here's the mod_verto configuration we're using: http://pastebin.com/4PDMXvW6 I can confirm the external RTP IP is set properly, however here's the returned SDP: http://pastebin.com/3vzyihRp The verto client is running behind NAT as well, but this doesn't seem to be the root of the problem as Sofia's own implementation of webRTC works fine. It is effectively sending its media to 10.178.x.x rather than the switch's public IP address. Please advise, thank you. -- Best Regards, Ciprian Dosoftei The information transmitted is intended only for the addressee and may contain privileged and/or confidential material.

FreeSWITCH TLS not able to receive calls
by Ahmed Habiba 01 Dec '14

01 Dec '14

Dears, I’ve configured FreeSWITCH with the below version with TLS/SRTPas per the recommendation in page “https://wiki.freeswitch.org/wiki/SIP_TLS” and it was strait forward, and I was able to connect and make make calls using zoiper, but I was not able to receive any calls after enabling the TLS/SRTP. "FreeSWITCH Version 1.4.13+git~20141103T195300Z~b942d0faa8~64bit (git b942d0f 2014-11-03 19:53:00Z 64bit)” Your kind feedback will be appreciate. Thanks, Ahmed Habiba.

multi tenet user directory management best practice
by ik 01 Dec '14

01 Dec '14

Hello, This question raises a lot, but no simple answer, so I'm trying to ask it differently. Let's say I have 5 FS servers and Opensips/Kamailio as a load balancer. I'm afraid that creating it using xml files is not dynamic enough, and requires duplications. mod_xml_rpc does not store that information on each update of the server itself, and there is no API for providing database management that I could find. So what is the best practice regarding of creating a user directory that all of the PBX will be able to handle ? Thanks Ido
