That's interesting. Our setup is almost identical to yours. We have 3 different SIP phones, one being an Aastra 480i. I have a Grandstream 4 Line one, and my wife has a Grandstream 2 line one. Both are relatively high-end phones (not inexpensive ones). The echo issues we've seen don't appear to be any different regardless of the phones in use. And strangely we never actually experience them on our end. The problem is always reported to us by someone calling in to us. This is what suggested to me to migrate my DID numbers over to them, rather than keeping them with Broadvoice. I think I might do that as a precaution anyway since its not likely to be a big problem for us to do it. The volume on our phones are not loud. I use a headset with my phone most of the time, which seems to give a better quality call to the other end, but there's not an issue with volume that could cause it. I am curious about the fact that you said after upgrading to 1.6.2, your problems went away. I didn't start with that version because it wasn't the current production version at the time. Do you think it would be beneficial to migrate to that version for me? Myles -- ======================= Myles Wakeham Director of Engineering Tech Solutions USA, Inc.
