I wouldn't recommend their SIP service for two main reasons:<br><br>1) Billing problems every single bill<br>2) Only supported inband DTMF (may now support rfc2833)<br><br>The quality was decent as they were ulaw when I used them. However they can't seem to deliver CNAM from everywhere on their origination product which is odd. Random DIDs would include CNAM and others would not.<br>
<br>Granted things might have changed as they are moving to new Sonus gateways.<br><br>Bottom line, decent quality voice if you don't need all the extra bells and whistles and can tolerate tons of billing mistakes.<br>
