I am a VTC technician and I mainly work on Tandberg's. I am currently working on a customers issue on their Tandberg in which she is able to make successful calls at 128k and 384K. However, whenever she tries to make a 256k call, it automatically tries to connect at 384K instead. The default call settings are currently set to AUTO and it is saved this way.
I have tried to complete a 256k call in my customers VTC room by adding #4#4 at the end of the phone number without any luck and I have also tried to set the default call settings at 256K and this did not work. All other call settings are set a the factory default, which is the way it should be, so I am not sure what else could be the issue at this point. I do not believe it is a line issue because I would not think that I would even be able to complete a 384K call if there was an issue with the lines. So I was curious if anyone else has ever experienced this issue and/or knew a possible solution?
