[Asterisk-Users] iconnect quality?

[Gregg Lebovitz]

Hi Lubo,

I appreciate your email to help with this issue, but I don't understand
your message. I assume your comment about format=slinear is to use
format=slinear in phone.conf instead of format=ulaw. If so, how does
this get you g723 to iconnect? Using format=g723.1 doesn't seem to work.
