Just wondering if there has been any discussion around the call quality from 2degrees to mobiles in Australia. It's something I've experienced for several months now but haven't quite managed to get to the bottom of. Basically when I call mobiles in Australia on various networks (primarily Vodafone), voice tends to be crackly or break up a bit so the words can be difficult to make out. It's not always that bad and often the issue is only noticeable at my end (other party does not notice any quality issue). However, on occasions, the other party also reports the same issue.

This has been tested with at least 4 different phones and 2 different 2degrees connections.

Is there anything I should be checking or testing from my end?

Thanks.
