Joe and I have been working with some very powerful VoIP stuff recently. One problem often encountered with VoIP is an awkward lag time (aka “latency”) between data going from the mouth of one caller to the ear of another. This used to be common in trans-oceanic calls. There is nothing worse than an artificial 2 second lag between every back-and-forth in an important conversation.

We created a test using two cell phones and a microphone. Phone #1 was put on speaker with the volume turned all the way up. The microphone was placed on the speaker of phone #1 and set to record. Phone #2 was held in the air. This is what we got:

This is the lag on a normal cell phone to cell phone call. It’s ~.34 seconds (dinner is being chopped in the background).

This is the lag on a cell phone to cell phone call hosted on the VoIP platform we have running out of Joe’s living room . Only ~.55 seconds! We’re excited to see what it gets down to when we move it to a high end hosting facility.

Pretty cool stuff.
