[ETS/PARC List] Repeater Audio

[Len Griffin]

Hope everyone is doing well! I've been using this time to learn by digging
deep into the Asterisk AllStar software.

 

I can report that the ' Galloping Ghost ' has ridden off into the sunset!

 

No more clicking / studdering audio on the repeater. Although there is new
AllStar software called ASL-1.01, we are using an older 2017 version of
AllStar.

The new version still has some issues yet to be resolved, and also had the
same audio issues, so there was no reason to change. The audio problem only
occur on the Raspberry Pi version, which uses an ARM RISC processor. This
processor has no internal timers which becomes a problem when decoding /
encoding digital audio streams.

 

Discussion about the audio issue revolves around something called ' DAHDI ',
which helps Asterisk maintain the audio timing.

 

I managed to get a module called ' dahdi_dummy ' installed on our older
software, and the audio has improved greatly.

 

Enjoy!
