Don't mix up the content of different posts. In one post, I explained how I used IAX and ILBC successfully on a sub 20k dialup link in Egypt (that was not a hotel but an office, BTW) and in a different paragraph I mentioned hotels in foreign countries as one of many locations where things can go funny. In another post, I responded to a question whether or not it might be possible to use an IAXy on a 33k or 56k dialup connection. There was no mentioning of any hotels and I did say that I have not used an IAXy myself. My comment that the IAXy *should* work on a 56k link was based on the fact that it supports ADPCM and if you check out the specs of most DSPs which do ADPCM you will find that they do 16, 24, 32 and 40 kbps, although the ITU ADPCM recommendation (G.726) talks about 32 kbps. Which chip the IAXy uses and which modes that chip supports, I guess only Digium can tell you. If you want to be absolutely sure, then you may just want to try it out. In fact, I think it would be very welcome if somebody with actual experience testing the IAXy on the road posted some feedback here. There is nothing that beats testing in the field. rgds benjk -- Sunrise Telephone Systems, 9F Shibuya Daikyo Bldg., 1-13-5 Shibuya, Tokyo, Japan. NB: Spam filters in place.
