Is Visual C++ the right language for a telecoms middle-ware project?

Hi all,
I have a requirement for coder / programmer / software engineer to work on a project that involves middle-ware in a telecoms network (i.e. between end telecoms device and customer site application). At a high level, the 'work to be done' is that of sending / receiving messages (not sms), dissecting these to pull out content, manipulate and present data from these messages and provide a GUI for an end user to display, format, interact with the data.

so... the question:
When looking for someone for this project, what is the most appropriate coding language that I should be looking for an individual to have is it Visual C++?

Cheers... Neil
