I have installed Red5 Server 0.9.0 and red5phone sip_r53. When i make a call , am not able to hear caller voice but he can hear me clearly. can any one faced similar problem ? please help.
Thanks and Regards,
Seniel
This can be many things! Need more info. From my experience the most likely reasons are fire-walled ports (check iptables rules, make sure you can send udp data to some random ports from remote machine to your host using netcat or something), then goes NAT. Are you behind NAT? If so, is your client NAT-aware, does it require STUN server, etc ?
Also it might be a good idea to check the speaker level on your machine and mic on the remote =)
When I search with keyword "Red5Phone" in Stackoverflow, and just 10 question appeared. :) I think our problems are same.
Hi, sunil. A moment ago, I successfully made a call using red5phone. I was using latest red5phone version from subversion, Red5 0.8.0, and Asterisk win32. I hope you also can make it.
Maybe like tuxxxedo says, it's about your Asterisk configuration.
don't forget put this in your extensions.conf
exten => 55,1,Playback(demo-echotest) ; Let them know what’s going on
exten => 55,2,Echo ; Do the echo test
exten => 55,3,Playback(demo-echodone) ; Let them know it’s over
try it.
I also experiencing this. I tried on Red5 0.9.1 and Chrome browser. I could not hear the voice both way even though dialer end up dialing. When i tried with firefox 5.0 and flash player 10 it worked on from red5phone remote phone but did does not work the other way. If the remote machine does to allow incomming udp as above reader suggest how do we fix this?

Its really good repo from Apple, right now in early stage but have really good feature
I recently bought a 3G dongle for a project I'm working on. I want my Raspberry Pi to be able to receive SMS messages and respond to them. I got a HSDPA 3g dongle with a 7.2mbps connection. I've set up the dongle on Windows with an A1 (not sure if you guys know this provider) sim and it works fine. I can connect to the internet just fine and also receive text messages (SMS)
However when I try connecting it to my Raspberry Pi (with Raspbian OS) then it doesn't work. It's always show as a "Mass Storage Device".
I tried my luck with usb_modeswitch and wvdial and with Sakis3g as well, but I can't get it to work. My problem with usb_modeswitch and wvdial was that even after I tried everything explained on these 2 blog posts (https://www.thefanclub.co.za/how-to/how-setup-usb-3g-modem-raspberry-pi-using-usbmodeswitch-and-wvdial ; https://nicovddussen.wordpress.com/2014/11/12/setting-up-your-raspberry-pi-to-work-with-a-3g-dongle/) it still didn't switch to the modem mode. It always stays at the "Mass Storage Mode". I saw an alternative and tried using Sakis3G, but with no luck as well. Seems like their website (sakis3g.org / sakis3g.com) is offline and you can't download certain .tar.gz folders/files anymore. I tried my luck with this blog post. (https://shkspr.mobi/blog/2012/07/3g-internet-on-raspberry-pi-success/)
And you guessed it, I couldn't get it to work either. It doesn't let me download the .gz folder/file because the website appears to be down.
It's a very big problem for my project and I would appreciate any help. It's really important. If anyone knows what I can do to fix this, please offer help. I'd really appreciate it.
Greetings.
Trying using tips supplied in this article
Unplug your modem
Open a terminal prompt
Install the usb-modeswitch package by typing in:
sudo apt-get install usb-modeswitch
EDIT... ADD REBOOT STEP
Reboot Pi
Plug the modem in,
Give it a couple of seconds and then try commands to confirm it worked
lsusb
ifconfig -a
You should see a new interface (Note the name of it - might be something like wwan0 )
To get this to acquire an IP address, edit the file /etc/network/interfaces and add the lines:
allow-hotplug wwan0
iface wwan0 inet dhcp
EDIT - REBOOT AGAIN
........
EDIT - UPDATE
Also note that the full version of sakis3G has this usb-modeswitch embedded in it.
You can still download code and look at instructions at old site that's been archived at:
http://web.archive.org/web/20130511202305/http://www.sakis3g.org/#download
I've been testing MTWWW for about a couple of days, and I've come to notice something.
I have to add the device to MTWW by going to a url on the device that looks like this,
protocol://hostname:+port/mobile
However, sometimes my device can't reach that address neither when I restart eclipse. When that happens I typically restart my computer and everything is fine and dandy again.
There was even one time that on that same screen that display the QRCode and URL to add a device, a notification appeared which showed something close to "RTW server could not start properly" or something like that.
This led me to believe that MTWW uses some other web server other that WL server to receive the recordings from the instrumented apps.
This also led me to believe that perhaps sometimes when the server tries to start the ports are already binded to some socket and it fails the initialization. Just speculation here.
However if there is a slight sense in what I written, is there a way to inspect the status of the RTW server, some dashboard perhaps?
Besides that, what should I do to fix when the RTW server didn't start properly? Rebooting the computer is pretty lame, there must be something more clever to do.
Oh, I've found this behavior on a mac osx box, on a windows one I haven't done so much testing.
Thanks in advance.
There is no dashboard for the server. But if yoy think that the issue come from the port, you can change it in the preferences. Please read http://www-01.ibm.com/support/docview.wss?uid=swg21678980
Hope its help
Background: I've a sensor hooked up to an arduino printing readings through the serial monitor. I want to log these in firebase.
I've done a bit of digging on this, and my research has shown me that an arduino simply can't handle the SSL needed to talk to firebase properly.
Any suggestions for workarounds? Checking SO and google's only turned up "it can't be done", but I figured I'd ask anyway. Any lateral thinking is appreciated, thanks!
If you figure out a way, let us (support#firebase.com) know. That would be an awesome hack!
Some thoughts:
You might want to look into the Spark Core (available for pre-order). They mention SSL support, though it's unclear to me what that means exactly.
You could proxy the requests through a server that can speak SSL. For instance, you could run a tiny node.js service on an Amazon EC2 box that just proxies REST requests to Firebase (e.g. using http-proxy).
If you're hardcore, you could try to get the Arduino talking to an external ethernet controller that has built-in SSL support (e.g. this one), but that's probably a big project. :-)
Longer-term, we might expose a non-SSL endpoint for Firebase requests that's specifically for this sort of low-end hardware use-case. Ping us at support#firebase.com if you want to start a dialog.
Here's a php script I whipped together to solve for Arduino no https.
It's basically a form that GETs to the php script and then sends it off to your Firebase database.
http->php->Firebase
https://github.com/robertcedwards/httpFirebase
*Make sure you add Heroku or your server to the whitelist of IPs that can post to Firebase
I know its an old question but visitors from google keep coming.
Have a look at this post: http://www.devacron.com/arduino-firebase/
[EDITED]
These arduino libraries might help:
firebase-arduino
https://github.com/googlesamples/firebase-arduino
https://github.com/ed7coyne/firebase-arduino
To install it:
Download the zip file, go to Sketch>Manage Libraries>add .zip file
Now you have access to
#include <FirebaseArduino.h>
and can begin using it with
Firebase.begin("example.firebaseio.com", "token_or_secret");
Follow the example at https://github.com/ed7coyne/firebase-arduino/blob/master/examples/FirebaseDemo_ESP8266/FirebaseDemo_ESP8266.ino
I have a thinkpad laptop and I would like to send AT commands to my modem once it is connected to the network. The interface that is used is '/dev/ttyACM0'. What is the best way to send my commands there? I tried gnokii but wasn't able to connect to my modem :/ I also tried echo'ing commands to the device, this worked, but it is not easy to get the output of the command to proceed with the computation. Maybe one of you guys has a better way to do this. TIA
Have you tried minicom? (assuming from your interface that you are using Linux)
Introduction to minicom.
Entering "minicom" in www.alternativeto.net gives a link to another terminal emulator for Linux called Cutecom, but I have no personal experience of it.
