However, the PA168 only supports a single voice channel. So, if it's a multi-channel PA168-based device, it probably just has a few PA168 chips in a single box.

In the case of all 4 channels being utilized, with the ever popular G.729 codec for example: without IAX2 trunking: approx 120.0kb/s in each direction with IAX2 trunking : approx 58.7kb/s in each direction That is less than half of the bandwidth utilization. Percentage savings will be even greater for the lower bandwidth codecs like iLBC and LPC. You could even do multiple calls over a _good_ dial up connection! There will also be savings (though less) when only 2 calls are concurrent, and when higher bandwidth codecs are used. However only when there is only one call will there not be bandwitdh savings (bandwidth utilization will actually be a little higher due to larger IAX2 overhead, but that is very small) PS There is a small error on http://www.voip-info.org/tiki-editpage.php?page=Asterisk+bandwidth+iax2 as it concerns iLBC trunking, I am correcting that now.
