We are a tech support unit and are presently having problems with inbound calls from US.
The calls do not come through, but this happens very irregularly. The calls either face a dead silence or get busy signals even when the line here is not busy. If the call does get through, the quality of the voice is too bad to put up with. There are long gaps and overlaps of voice and intermissions and so on.
I would like to get some help in investigating the issue and coming up with solutions.
Can you please help?
