I have made a fresh install using last version of Vicibox 6.0.3(all in one express installation on a workstation). With default steps of official manual I get a very poor audio quality even between local sip accounts. The sip client software is Zoiper on Ubuntu. Now I have to ask about the default audio codec that is included in Vicibox and do I need to install a new codec like g729 or other. I want only a fair quality with minimum changes and efforts. I'm new in VoIP and Asterisk systems

Thanks
