Its not a limitation. Its an architectural design which is based on pulse
code modulation (pcm) standards, which essentially says:
- 8,000 audio samples per second,
- each sample is an 8-bit value
- resulting in 64,000 bits/second (like g711 codec standard)
Thank you for your answer, but I don't think you read/understood my
question?
The Zaptel driver uses a 8 byte buffer for buffering G.711 in each
direction. This has nothing to do with the sample rate, but how large
packets you can buffer the voice for to be transported through the PCI
interface. I get the impression that the Digium boards are limited to 8
bytes (1 ms ) by reading the zaptel driver. But, I don't know this cause
I have no hardware manual that cover the PCI interface. I was hoping
that the Sangoma boards offered a more variable buffer size???
