I have a very well specified Windows Server connected to sound card input via mod_portaudio.

I want multiple callers to be able to listen (only) to the incoming feed, so I set up dynamic conferences, with the dialplan flags setting mute. An autocall bridges the portaudio.

My assumption is that this is the best way. I am happy to be wrong if there's a better plan.

The problem is that delay builds up, seconds every minute on the conference.

I have RTP-Timer-Name=none and enabling both RTP AutoFlushes.

Any other suggestions I could try? Would CentOS have better timing?

I don't need callers to hear each other, but I'm sure that I'm missing something.

Any thoughts?
