Optimization testing: Ensure ptime of 10ms to let VoIP flows to flush faster #4

Default audio codec tend to use ptime (amount of milliseconds per packet) to be 20ms.

As we need to speedup processing for DSP modem ingestione, we could try on Asterisk and PJSIP side to enforce a ptime to 10ms (assuming the codec does allow).

This will move from 50 packets per seconds per leg to 100 packers per second per legs, but improving the latency, hopefully leading to better DSP modem processing
