Today sadly sees the demise of another mobile operator, Dolphin Telecommunications Ltd. But more importantly it puts question marks over the Push To Talk business case in the short term. Dolphin, being one of the new innovative wireless companies, had put faith in this technology and has now paid the ultimate price for focusing its business on a solution yet to be proven. While many vendors continue promoting the push-to-talk, the fact of the matter is that few phones are currently available on the market supporting this feature and consumers have yet to even become aware of this solution.

While analyst firms continue to have reservations about how this technology will gain a foothold, vendors remain optimistic as to why operators should feel this is a technology for the future. Therefore push-to-talk is a possibility for the future but it remains to see how vendors continue to focus on delivering this particular solution or change their direction depending on market acceptance.
