VC codecs
by Bipin Patel 02 Jun '16

02 Jun '16

I wanted to know what codecs can I use with verto communicator for audio only and to bridge calls to sip gateway. Basically wanted to know if it can handle g711u because most of my gateways use that only along with g729 and g723 but am not interested in those

How to pause and resume the IVR flow
by Naveen Tamanam 02 Jun '16

02 Jun '16

Hi All, I have a simple question. Is there any way to pause and resume the IVR flow in freeswiitch. Case Study: Controlling call through event socket. I would like to play few sound files from event socket by pausing the running IVR and then once I finished playing sounds using event socket, I would like to resume the IVR flow. Let's say IVR is running, I would like to execute random action from event socket by PAUSING IVR, once action is finished I would to resume the IVR from from where I paused it. Is it possible ? -- Thanks & Regards, Naveen Tamanam

Re: [Freeswitch-users] Is there a way for FS not to send back any response to INVITE
by Dave Horton 01 Jun '16

01 Jun '16

I do this with my proxy that fronts freeswitch (https://www.npmjs.com/package/drachtio-fs-load-balancing-proxy <https://www.npmjs.com/package/drachtio-fs-load-balancing-proxy>) by evaluating SIP headers for the common sip scanner signatures and dynamically adding the senders to an iptable black list. This does result in a 100 Trying going back to the sender (since that is sent by my sip stack before proxy processing) but no final response, and every subsequent message from that address is silently dropped.

Is there a way for FS not to send back any response to INVITE
by Oleg Stolyar 01 Jun '16

01 Jun '16

Hi, In order to protect against scanning attacks I'd like for FS to not respond to INVITES unless they match certain conditions. I understand that currently FS always responds with 100 Trying right away before processing the call and then, if the call does not match anything in the dialplan, responds with a 302 Moved Temporarily. The 302 can be replaced with another response code (for example 403 Forbidden which is what I am doing now) using the *respond* dialplan app. However, that might encourage the scanner to keep trying. So I guess there are two questions: 1. Is there a way not to send back 100 Trying at all? 2. Is there a way to not send any final response?

Webrtc Verto jsapi
by stevem 01 Jun '16

I was not able to find any documentation on this. Basically all I want to do from my frontend. Is post an event to the backend. Basically run the command: uuid_broadcast 69d58330-7f7f-4e52-bb2c-9e25d9f5238b event::Event-Name=HOLD. I'm using FreeSWITCH Version 1.4.21~64bit I got the verto/webrtc working using the demo located here: https://webrtc.freeswitch.org/verto/index.html#page-main I'm able to connect to the dialplan and drop the caller (PSTN/ITSPs) and verto client into a conference and the audio is flowing. I just want to send a message to the backend to tell it to do things. In my example above I want to set the caller on hold. My verto connection in javascript looks like this: $.verto.init({}, bootstrap); function bootstrap(status) { that.vertoHandle = new jQuery.verto({ login: userId + '@' + host, passwd: password, tag: "vertoAudio", socketUrl: 'wss://' + host + ':8082', audioParams: { googAutoGainControl: false, googNoiseSuppression: false, googHighpassFilter: false }, iceServers: true }, vertoCallbacks); } var vertoCallbacks = { onWSLogin: onWSLogin, onWSClose: onWSClose, onDialogState: onDialogState }; On successful login i make a call: that.call= that.vertoHandle.newCall({ destination_number: that.liveCall.ani, caller_id_name: user.firstName + ' ' + user.lastName, caller_id_number: userId, useVideo: false, useStereo: false, userVariables: {} }); Thanks alot. This is my first post and I've only been doing Freeswitch for a few months. I have alot of experience in Asterisk though. Let me know if more data is needed. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Webrtc-Verto-jsapi-tp7596220.… Sent from the freeswitch-users mailing list archive at Nabble.com.

SIP gateways, context
by Yu Boot 01 Jun '16

01 Jun '16

I use single profile both for SIP gateways and for password-protected clients. Why FS ignores context parameter in SIP gateway settings? I can route inbound calls from these SIP trunks only in "default" context by inbound IP address. Password-protected clients (from directory) don't suffer from this, all inbound calls are routed via respective contexts. Sent from my ASUS

Freeswitch Inbound Calls No sound
by Deepika Yadav 01 Jun '16

01 Jun '16

Hi, I need to make calls from a mobile number that can be answered by Freeswitch extension playing an IVR. To achieve this, I have configured a VOIP-GSM gateway having inserted a mobile sim that upon receiving the incoming calls forwards it to a SIP URI. Gateway Settings: PBX IP : ec2 public ip Protocol : SIP Port : 5080 Target: 9811806537 Freesswitch resides at Amazon ec2 cloud, Dialplan for public context is : <extension name="mydid"> <condition field="destination_number" expression="^(9811806537)$"> <action application="transfer" data="4444 XML default"/> </condition> </extension> Default Context : <extension name="ivr_demo"> <condition field="destination_number" expression="^4444$"> <action application="answer"/> <action application="start_dtmf" /> <action application="sleep" data="2000"/> <action application="ivr" data="rhd_ivr"/> </condition> </extension> where Server IP - XX.XX.XX.XX Gateway IP- YY.YY.YY.YY Freeswitch logs can be found here : http://pastebin.com/7BbM5dWD <http://pastebin.com/i4gs9uVJ> Files sip_profiles/external.xml sip_profiles/internal.xml <param name="ext-rtp-ip" value="XX.XX.XX.XX"/> <param name="ext-sip-ip" value="XX.XX.XX.XX"/> Any pointer to move forward would be highly appreciated Reagrds, Deepika

SIP Message question
by Nagorny, Dimitry 01 Jun '16

01 Jun '16

Hello List, AFAIK, all INVITE SIP messages (INVITE sip:100@mydomain.com) are going through the set up dialplans. Are all MESSAGE SIP messages (MESSAGE sip:100@mydomain.com) also go through these dialplans? If no, how can I handle them? This might be a stupid question but any help is still appreciated. Best Regards Dimitry Nagorny Trainee
