[Asterisk-Users] SIP + Grandstream 100 + TDM100P = lots of local echo, & questions about call transfers

I tried putting in

txgain=100%
rxgain=100%

and zaptel wouldn't load telling me I had wrong parameters in my zaptel.conf
i'll try again with txgain=5.0 but my setup is at a client so each time a
day passes
and i have to go round to the client just to try things out ... it's a bit
annoying!

my 2c ..

when is there going to be some concerted effort at documenting some stuff?
today I discovered by change that you can dial #xxxx to transfer to
extension
xxxx .. surely these are stuff that could be put down in writing somewhere ?

cheers
Dave
