The poor throughput you reported for data transfers made while a voice call was active is almost certainly due to an underpowered CPU in the DVG-1120M. Even the fastest VoIP codec uses only 64kb/s in each direction, plus a little header overhead. So your Internet data throughput during a call should have decreased by no more than 64kb/s even if voice traffic is given unconditional priority over data traffic. The actual drop should have been even less considering that most VoIP services use codecs slower than 64 kb/s.
The fact that your throughput dropped to almost nothing during a voice call can only be the fault of the unit, either because of an underpowered CPU or a firmware bug of some sort that causes lots of data packets to be lost while a voice call is active. |
