Aastra yesterday announced the addition of the 51i SIP telephone to their 5i Series of powerful open-standard, enterprise grade terminals

The model 51i joins the existing 5i Series family consisting of the 53i, 55i, 57i and the 57i CT models and extends one of the industry’s most complete VoIP telephone offerings.

The 51i addresses the need for a lower priced, entry level single line SIP based telephone for light use in small and medium business applications such as lobbies, common areas, or individual user environments. The 51i retains the style and core features of the 5i Series including: XML browser capabilities, full duplex speakerphone, extensive storage capacity and simplified deployment. While the 51i does not include some of the enhanced features that can be found in other models in the 5i Series such as headset support, backlit display or expansion module capability, it does deliver an excellent mix of value and performance in a carrier/enterprise grade quality IP phone.

The Model 51i is available in both English and Symbol keypad versions signified by the following manufacturer part numbers:
