AACnet is a web design/software development company. We offer Voip products to support the commercial PMR radio sector. Our flagship product IPOX5 PRO LINK is a software and hardware option for linking PMR radio sites over the internet. It allows for departmental access to the network using PCs in workers offices. We have recently released this software to the public for use in NHW group linking or even private PMR radio to a 'family network' - for this no purchase is required and no further hardware is needed, as you can use serial port switching or radio vox.
