Im using Asterisk pbx hidden behind openvpn server. Endpoints are installed on Android Phones. This configuration is working quite good, but voice quality gets very bad when phone user is driving a car (so we have lot of handovers). Im using 8k codec (speex),
Could some1 give me any clues how could i improve my configuration to get better voice quality?
I already set up:
My full config:
server 10.8.0.0 255.255.255.0
push "route 10.1.0.0 255.255.255.0"
push "redirect-gateway def1 bypass-dhcp"
keepalive 10 120
Best regards, Konrad
