Interferance whilst using C2C

[maturesally38k]

I have been camming using justcamit for a few years now, but in the last few months have been getting a lot of noise interference whilst using C2C, also a lot of echoing, when I speak, it echos a few times, which is very off putting. Has anyone else had this problem, and if so, is there anything I can do to stop it. It is not just me that can here it, but anyone else in my room at the time. Thanks in advance for any help.
