[Asterisk-Users] Sound quality with Xten Xlite softphones...

[Sascha Ferley]

I found that the IAX phone (softphone) seems to work well.. Actually
strange i seem to get better voice quality (both directions) out of it,
when talking via a network based connection. PSTN is another issue.
Plus it is easy to provision and seems to be using alot less bandwidth.
