[Asterisk-Users] G711u sound quality decrease with upgrade from 1.0.7 to CVS-HEAD?
Hi, I was running asterisk 1.0.7 but we've upgraded now to CVS-HEAD. I've noticed this.. and several people have commented that audio quality seems to have gone down hill. Just going phone-->asterisk-->PRI. I've not changed the configuration files during the upgrade. sip.conf is: allow=ulaw allow=ilbc allow=g726 allow=g729 allow=g723.1 And all the phones had been using ulaw before. The audio is not bad.. but sounds much more like a cell phone (Even with ulaw G711u) and 'under water'. Any thoughts?

I just noticed one of my phones on a call as: 400 e8516be0704 00101/02552 ilbc No Rx: ACK Why would it default to ilbc when ulaw is available (worked with 1.0.7), etc?
