VoIP quality monitoring
by Stanislav Sinyagin 18 Nov '15

18 Nov '15

Greetings, Here's a short follow-up to yesterday's presentation of Zebbra guys. What Markus and Roland have presented, is an approach to monitoring the quality inside the box (CUCM in their case). But there are actually ways to monitor the quality outside of the box, and they have been around for a while. For example, I've seen a demonstration of Malden MultiDSLA tool over 10 years ago. At that time they only had the analog interface that emulated a handset, and two Malden boxes were sending an audio sample to each other and assessing the quality of received audio. The tool is quite expensive though. There are currently several commercial solutions for audio quality analysis: POLQA (expensive), recommended by ITU-T: it compares two audio files and produces the quality assessment score. Sevana AQuA (less expensive): it also compares two audio files and produces several quality metrics. I compared it with PESQ (predecessor of POLQA), and AQuA works significantly faster. It was very helpful in detecting lost RTP packets in the tests where I could not place a packet sniffer wherever I wanted. There are also various approaches to passive quality analysis, and some are documented in ITU-T P.563 and G.107. Sevana is also offering its PVQA tool that tries to detect packet loss and audio distortions by analyzing the input audio. I could not find any open-source tools which would help in quality analysis at the audio level. But there's plain old tshark which produces the loss and jitter statistics for RTP streams, and it's pretty efficient if you are able to capture the traffic at the receiving end. Also VoIP monitor provides the ability of G.107 analysis on captured data packets. Here's my detailed article on using Sevana AQuA: https://txlab.wordpress.com/2015/06/02/quality-assurance-for-voip-calls-2/ And here's my demo lab, and you have a possibility to send an audio recording for Sevana PVQA analysis: http://voxserv.ch/demolab.html cheers, -- Stanislav Sinyagin Senior Consultant, CCIE #5478 ssinyagin(a)k-open.com +41 79 407 0224

Mikrotik SFP no link
by Andre Timmermann 17 Nov '15

17 Nov '15

Hello, I recently bought a Mikrotik CR1009-8G-1S-1S+. I added a Mikrotik S -31DLC20D SFP module to connect my internet uplink. The uplink provider confirmed that the uplink should be working with wavelength 1310 nm, single mode, 1GBit, no auto negotiation. Unfortunately the webinterface shows "no link". Firmware is 6.33 and I rebooted the device - still no link. Please note that I do NOT get a value for sfp-rx-power in the webinterface or the following dump. Is that a hint that the fiber is not OK or is that conclusion invalid? /interface ethernet monitor 9 name: sfp1 status: no-link auto-negotiation: disabled sfp-module-present: yes sfp-rx-lose: yes sfp-tx-fault: no sfp-type: SFP-or-SFP+ sfp-connector-type: LC sfp-link-length-9um: 20000m sfp-link-length-50um: 550m sfp-link-length-62um: 550m sfp-vendor-name: Mikrotik sfp-vendor-part-number: S-31DLC20D sfp-vendor-revision: A0 sfp-vendor-serial: MT50617H2074 sfp-manufacturing-date: 15-06-24 sfp-wavelength: 1310nm sfp-temperature: 50C sfp-supply-voltage: 3.237V sfp-tx-bias-current: 21mA sfp-tx-power: -7.055dBm Best regards, Andre

looking for a sinmple telephony monitoring tool
by Amann Hans-Peter 06 Nov '15

06 Nov '15

Hello, We are looking for a tool that permits to check the behavior of a telephony system at the level of the end user. The idea is to launch telephone calls at regular intervals one system, to pass through the public network and to check on the PABX system under test (Siemens HiPath 4000 with Trade-Boards) that the voice call arrives (signaling path) and can be established (voice path). Our problem today is that we can check plenty of internal interfaces and links, but we do not known if all the higher level protocols behave well. Thanks for your ideas !
