We are getting a sudden burst of complaints concerning TCP SIP working but no UDP RTP audio flowing, specifically on T-Mobile. Is anyone else seeing this?
I'm seeing the same. I get one way audio from server to the handset. The call drops after 5 seconds due to not detecting 2 way audio. ~Jared Geiger On Thu, May 18, 2017 at 12:35 PM, Liudvikas Bukys <Liudy at bukys.org> wrote:

Hello, I was wondering if anyone could suggest some open source testing and quality monitoring applications for VoIP. From time to time we have some remote clients who are facing voice quality issues on their endpoints and I have no real good way of troubleshooting or pin pointing the problem. Any help or tips regarding best practices would be greatly appreciated. TIA, Jamie
Hello Sir I use Homer5 to view RTCP-XR reports, statistics from RPTEngine and call tracing among a bunch of other stuff.. It's free and awesome (about to become HEPIC) https://github.com/sipcapture For network tests I use iperf, smokeping and stuff like that. Kind regards Andy On Tue, 23 May 2017 19:11 James M, <jm8269 at outlook.com> wrote:

This may not be quite what you're looking for, but 'The Test Call' has proved very helpful for us so I wanted to share it with this community (and reminds me I should probably donate). The Test Call at http://thetestcall.blogspot.com/ hosts a handful of PSTN numbers that you can call and test several functionalities: -Record and playback a message (test 2-way audio) -DTMF testing -Real-time Echo Test (test latency) -Playback music on hold (test sustained connections for drops on inbound audio) -0-4KHz audio sweep -Caller ID Readback Hope that's helpful to you or someone else on this thread, Jacob S? ? ? -----Original Message----- From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of James M Sent: Tuesday, May 23, 2017 1:11 PM To: VoiceOps <voiceops at voiceops.org> Subject: [VoiceOps] VoIP Testing Hello, I was wondering if anyone could suggest some open source testing and quality monitoring applications for VoIP.

From time to time we have some remote clients who are facing voice quality issues on their endpoints and I have no real good way of troubleshooting or pin pointing the problem. While it's not completely free, I couldn't live without voipmonitor for this very use. I install a sensor in the client network on a mirror port or on the phone system and get to see exactly what they see, from a voip perspective.
The collection software is open source but the gui is invaluable.
Mark, what type of device are you using as the sensor? I've been looking for a raspberry pi with two Ethernet interfaces but I can't seem to find one. I'm assuming we need on port for port mirror traffic and one for internet access to send the data back to voipmonitor. Thanks, Shripal

I currently use Celeron or Atom based single board devices. https://www.amazon.com/Jetway-Networking-Appliance-Embedded-JBC373F38W-525/d... are pretty OK. There's also a celeron model. They both have 4 interfaces. On 5/23/2017 5:20 PM, Shripal Daphtary wrote:

You can use a USB to ethernet dongle on a raspberry pi to bring up two NICs. I have a VoIP monitor capture node in our lab built this way and it works well. On Tue, May 23, 2017 at 5:21 PM Shripal Daphtary <shripald at gmail.com> wrote:

You?ll need to be aware of what level of traffic you?re trying to mirror into the Pi. The onboard NIC is riding the USB bus which you?ll then share with the external USB NIC. If the Pi is receiving too much data, it?ll drop packets. This would appear as an RTP problem even if there isn?t one since RTP packets would be lost. Also consider the packets per second that the Pi CPU can interrupt for. 20ms = 50pps From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Shripal Daphtary Sent: Wednesday, May 24, 2017 9:43 AM To: Christopher Aloi; Mark Wiater Cc: voiceops at voiceops.org Subject: Re: [VoiceOps] VoIP Testing Thanks!

Shripal, There's no off-the-shelf RPi with dual NICs, but any class-driver compliant USB NIC will work fine as a second interface, as long as you don't need more than 100mbit wire speed. We do this on multiple RPis. It's literally plug-n-play :) Pete
Thanks Pete. We're testing now. Thanks, Shripal

If you need more horsepower, for about $100 extra, you can load linux on a Netgate appliance.
