Sipura SPA-3000

Sipura SPA-3000

Unlike the other VoIP gateways we have tested, the SPA-3000 from Sipura can only be used to handle a single PBX extension. However, for many teleworker applications that’s all you really need. And at just over £80 (ex. VAT), the Sipura gateway is a very cost-effective solution.

Solwise VOIP-EL404

Solwise VOIP-EL404

The UK importer of a range of Taiwanese VoIP products, <a href="http://www.solwise.co.uk">Solwise</a>, provided us with a pair of 4-port gateways for review.
