The call quality is really pretty good. I think better than Vonage over an FXO bridge. If you are looking for a home provider with direct SIP support and local phone numbers this is a good choice. If anyone has questions or comments about my configuration please pass them along. I have noticed that if you don't put fromuser=phone# then the extension caller id passes through. Also the major annoyance is why outbound calling gives no ring indication. I'm still looking into whether there is no ring indicator being sent back, or how to create one. Using the little 'r' at the end of the dial string just seems to prevent the call from going through. Username is your 10-digit phone number. Password is in the .reg file they sent you via email. I signed up for the USB phone, so I don't if they send a .reg file if you went for the MTA. sip.conf register => 1234567890:password@myphone.voiceglo.com [myphone.voiceglo.com] type=peer username=1234567890 secret=password nat=no host=myphone.voiceglo.com disallow=all allow=ulaw allow=alaw canreinvite=no qualify=200 restrictid=no fromuser=1234567890 fromdomain=1234567890.voiceglo.com extensions.conf exten => _91NXXNXXXXXX,1,Dial(SIP/${EXTEN:1}@myphone.voiceglo.com) cameron.
