The directional buttons in this pad are the only case sensitive soft keys on the phone. The phone has a very small 3-line display resting on top of a navigation pad. Others correspond to common call handing functions like ‘hold’, ‘transfer’, etc. Like other Aastras, there are lots of dedicated hard keys, some of which are customizable. The Aastra 6730i is a lot like many of the Aastra phones we’ve seen. In this review, we’ll see if the same quality can be found in a device that’s a fraction of the price of most VoIP phones on the market. The OnSIP team has already given a positive review to the 6757i, one of TMC’s Tom Keating’s favorites. Since Aastra released its own wideband audio technology, Aastra’s ‘Hi-Q’, all models in the 67xi lineup allow users to experience wideband audio via the industry standard G.722 codec. The 6730i (firmware v2.) is the new entry-level addition to Aastra’s line of 67xi SIP phones, which range from the 6730i to the new 6739i executive class IP phone. Today we’re going to take a look at another one. The new Polycom 335 and the Cisco SPA504G are two moderately priced ‘HD’ phones that we’ve already reviewed. Some of these devices can cost you a bundle, but there are also very affordable options on the market. If you or your business is looking to take advantage of some of these services, then you’ll need an ‘HD’ phone. Providers who had not jumped on the bandwagon in the past are getting the picture and rolling out wideband support. The truth is that the hardware has been ready for years and the support is just catching up. OnSIP has supported the industry standard G.722 wideband codec since ‘HD’ IP phones first came out, and since then, we’ve been huge fans of the increase in voice quality. The interesting thing about wideband audio, more popularly known as ‘HD’ voice thanks to the marketing people at Polycom, is that it has been available for quite some time. It is beginning to look like ‘wideband audio’ is the new buzz term in the VoIP industry.
