To followup my question below, we're looking for a way to record in Asterisk at 16kHz but send only 8kHz (ulaw) to our peers. Is this possible?
Btw, I wanted to ask this as a followup to https://community.asterisk.org/t/change-sample-rate-to-16khz/73842/2 but whenever I try to login to that site, I get "Sorry, there was an error authorizing your account. Perhaps you did not approve authorization?" I've never received an email asking to verify my address, if that's what this error means. I just tried re-registering, too.
