I have couple of questions which most likely will help solve my problem with iax sound and help many more like me. I use g729a and have proper license for it however, i am not using digium’s hardware. I am simply going VoIP over ethernet but my voice quality with iax trunking is pretty bad (inconsistent and choppy) with g729a for one user with 512/512 connection.
I just upgraded my asterisk to the latest 1.2.7 as well. My frame buffer in my lilo.conf is also off as someone mentioned that it could make the sound choppy.
Question1: I can see the zapata.conf in /etc/asterisk and zaptel.conf in /etc. In my case are these files needed?
Question2: In my extensions.conf I can see the section for TRUNK and CHANNEL where its ZAP/g2 etc are defined. What should it have there? Since mine i believe is only a pseudo channel, I am not sure if the default in the extensions.config is correct.
Question3: I saw in some forums that there is a rtc driver for 2.6 kernel. Would anyone have any comment on whether i should use it?
thanks in advance.
