Voxalot supports G.711u and G.711a!!! They just refer to it as ulaw and alaw. Just set the codec order in Voxalot's provider section appropriately or delete all except alaw and/or ulaw.
See affinity's posting above:

Wikipedia about G.711:
Quote:
There are two main algorithms defined in the standard, the µ-law algorithm (used in North America & Japan) and A-law algorithm (used in Europe and the rest of the world). Both are logarithmic, but A-law was specifically designed to be simpler for a computer to process. The standard also defines a sequence of repeating code values which defines the power level of 0 dB.
The µ-law and A-law algorithms encode 14-bit and 13-bit signed linear PCM samples (respectively) to logarithmic 8-bit samples. Thus, the G.711 encoder will create a 64 kbit/s bitstream for a signal sampled at 8 kHz.
