I have the following configuration, 3 sites all connected by vpns to each other. In the main office I have an Asterisk 2 box with a budgetone 102, this works perfectly here, voice quality is excellent. In the two remote offices i have a budgetone 102 installed and connected to the asterisk box in the main office. Everything is working fine but the call quality if very bad to the remote offices. The voice is choopy, scratchy and has echo. Does anyone know how I can fix this.
