Unlike Fonality, ISPhone bundles a dedicated PSTN line to handle VoIP traffic.
Managing director Gavin McDougal takes the opposite view to Englaro as he insists it is still important to keep carriage separate. "It does really matter what network you're using when you're connecting these devices and solutions."
A bugbear with IP telephony is pinpointing the cause of poor call quality. McDougal says that before he began selling dedicated carriage he had complaints from customers over call quality using a single ADSL2+ connection for voice and data. The culprit could be the ISP supplying a line with high contention rates (number of connections a line), an employee downloading large files or interference from security devices.
In situations where insufficient bandwidth is a problem, McDougal says adding a dedicated VoIP line makes more sense than increasing the size of the main connection.
ISPhone provides dedicated SIP trunks or VoIP tails to guarantee the best call quality and control. "From our experience it has been a major improvement and the number of customer complaints has gone down massively," McDougal says.

ISPhone sells a dedicated a 2 MbpsADSL2+ VoIP tail to its channel partners for $59 a month with unlimited calls. "They can sell it at $79, $89, whatever they want," says McDougall. "But that might replace 10 lines for an average $30 a line."
The ISP has branched out into selling non-VoIP bandwidth as well. Speeds increase all the way up to 30Mbps.
This month ISPhone is launching a hosted IPPBX service. McDougal says companies are demanding hosted solutions because they can add features as the business grows.
"We think the mobile phone and the office environment will get closer and closer and you can have all the features of your IPPBX on your mobile phone," McDougal says.
