    I have some remote phones. They work great accross the internet using the ulaw codec (g711)(audio and dtmf) however when I use the g729 codec I can get audio and dtmf to work except when I go into vm. Then no matter what I enter in for a password it tells me invalid. I have tested this locally and it works fine on g729 just not accross the internet. Anyone else had this issue? So right now my remote phones are on g711 and I would really like to get them to g729 to save on bandwidth.
