[asterisk-users] Issues with a Linksys SPA 2102 and asterisk

[Erick Perez]

Topology:
analog_phone-----SPA2102-----Navini_Wireless_Router------ISP------Asterisk
A ping against the asterisk server shows aprox 145ms roundtrip.
128kbps upstream
512kbps downstream
g729a as codec
signal quality of the navini router: 100%

The ATA operates correctly in every form, however sometimes when
someone is talking to me (the other person is at pstn) and then I
start talking the other end receives garbled voice and i need to start
talking again. So I played with the jitter buffers in the available
modes (low, medium, high) (direction upward, downward both) and it
seems i cannot improve my voice experience.

Any gurus out there with experience with the SPA 2102 against asterisk 1.2.14?

thanks,
