hi ..
I have an asterisk system with three TDM100P (single port FXO) cards
and 10 Grandstream 100 phones connected to it ..
The TDMx00P cards are FXS cards.. :)
1st question:
when i phone out
or receive a call from one of the SIP phones onto the PSTN, there is
a LOT of local echo in
these are taken as db right? 3.0 db = 100%
but, in some cases we've had to do txgain=9.0
is that bad, martin? are there any hardware limitations on this?
does zaptel really accept %? if so, then it should be taken as a
percentage, not pseudoDB (tm)

my error .. the cards are X100P which is why I wrote FXO.
The Grandstream phones are on a LAN, the * server connects to the
phonelines
via the X100P cards. When I call

Don't use %'s with txgain/rxgain
for
txgain=5% is equal to txgain=5.0 and that might be too much

there is a VERY big amount of echo, ie. I can hear myself in the earpiece.

could you send me the exact syntax for rxgain / txgain?
I think that might help towards my problem
becuase i'm having to turn the handset volume all
