[Asterisk-Users] Asterisk and Grandstreams on marginal broadband...

[Kim Lux]

We've got an office with a marginal broadband connection.

Do you think Asterisk + Grandstreams can be tuned to give a good quality
call on with this jitter/latency ?  This is the only broadband supplier
in the area, so changing carriers would be difficult.

I made a call from the Grandstream with * and it was a bit choppy and
had some echo.


Thanks.
