I'm not sure how to make an educated decision on this, that is, if we could get by with SIP. I tried http://www.voipqualitytest.com/ and this is what it shows: 1. Random time during work day: Speed test statistics --------------------- Download speed: 10537 kbps Upload speed: 1115 kbps Download consistency of service: 64 % Upload consistency of service: 67 % Download test type: socket Upload test type: socket Maximum TCP delay: 118 ms Average download pause: 1 ms Minimum round trip time to server: 54 ms Average round trip time to server: 57 ms Estimated download bandwidth: 13651 kbps Route concurrency: 1.2954974 Download TCP forced idle: 33 % Maximum route speed: -- VoIP test statistics -------------------- Jitter: you --> server: 1.1 ms Jitter: server --> you: 24.5 ms Packet loss: you --> server: 0.0 % Packet loss: server --> you: 0.0 % Packet discards: 0.0 % Packets out of order: 0.0 % Estimated MOS score: 3.6 2.
