ss than $200 per person, the telecommunications departments have a great incentive to adopt softphones, which is the primary reason for the trend of the dramatic increase in the number of softphones. The major inhibitor to the increased adoption of softphones is end-user behavior. End users often have frustrating experiences with softphones because of the lack of correct utilization. When softphones are used with a high-quality headset, in an environment in which the IP connectivity is high quality and consistent, the user experience is usually excellent. Unfortunately, many users turn to softphones in less than ideal conditions, such as hotel rooms, while downloading a large amount of other traffic, or in noisy environ- ments. Any of these, or similar, situations often results in a negative user experience. However, an important component of this trend is that SIP trunking solutions need to accommodate endpoints such as softphones with features where the network components of SIP trunking, such as DSPs, compensate for the lack of the feature at the end user. Secondly, SIP trunking solutions should adapt to the variable bandwidth availability of these types of devices and support a wider variety of codecs, such as iLBC or G.722. Chapter 2: Trends in IP Telephony 17 The summary of softphone trends is as follows: Lower-cost endpoints Wider adoption of softphones in business environments More reliance on network components providing the role that was traditionally done in the hard phone More robust codec support as a requirement of SIP trunking services Enterprise WiFi IP Phone Trends The WiFi phone is a unique combination of technologies that has yet to establish itself as a prevailing force in enterprise telecommunications However, it plays an essential role in enterprise locations where staff is homed to a physical location, yet are required to roam within it. Specific examples of this type of enterprise are hospitals and retail locations where WiFi enterprise IP Phones have been successful. The WiFi IP Phone is
