Transcode from ulaw to opus

Asterisk Asterisk Support
1

Hi, I moved my asterisk server from debian to ubuntu. and now i cant dail to my home assistant voice agent using sip.

home assistant voip requires opus. but i have ulaw as default for my grandstream phones.

I could fix this with asterisk-opus install with debian.
but with ubuntu im not so lucky.

opus is missing. here
