DrayTEL SIP Trunk and DSL Trunk Packages
DrayTEL provide three types of trunk. The Classic/Prepay account is our original account type, ideal for a single SoHo user or household using a VoIP telephone or VoIP enabled router. The business trunk services all include enhanced levels of customer support; the trunk elements are the same but the DSL trunks are provided together with the one-hop DSL line, ensuring best possible call quality and reliability. (For more explanation, see here).
What is a DrayTEL DSL Trunk (Voice Plus/Voice Pro) ?With a conventional ADSL line, in order to route calls to the VoIP gateway (DrayTEL server), your traffic goes firstly to your own ISP and then via any number of other public networks/ISPs before eventually getting to the server. Each of these 'hops' introduces delays and each part of the route is subject to its own congestion or packet loss - the reliability and quality of the call depends on many different company's networks and general Internet congestion, factors which are completely out of your control. Your voice traffic is competing for bandwidth with every other Internet user. These factors can contribute to variable call quality and also effects such as jitter and packet loss. By using DrayTEL's DSL Trunk, we provide not only a resilient DSL line with no contention but a direct route back to the DrayTEL server. Your voice traffic passes through our private network and does not share bandwidth with any non-voice traffic or pass over any other public networks at any point. This ensures the very best call quality, as well as increased security. Your voice traffic is not competing with any non-voice traffic and not delayed by multiple network hops.
Pre-requisites for a DrayTEL DSL Trunk
In order to have a DrayTEL DSL trunk, you need to have a BT analogue line on which the DSL service can be provided. Your analogue service will continue to operate normally. If you do not have a spare line available, DrayTEL can arrange for one to be fitted (subject to additional charges). DrayTEL's DSL is available is most of the UK but a specific survey/check of your line needs to be conducted to confirm availability at your location. You are not committed to and do not pay for anything until this has been confirmed.
