| OnSIP | Very pleased customer. 11/03/2012 - 12:00 | Excellent call quality. Very friendly admin page. Cheap and reliable. Allows multiple SIP ATA registrations per account which is a big plus. | Must provide a human name for each extension. Would prefer a person or location option. | Excellent call quality inbound and outbound. No charge outbound caller ID name support. 10 devices per extension simultaneously. I trust OnSIP more than any other provider based on their level of support, quality and ease of use. |
