[Asterisk-Users] echo sidetone grandstream and tdm400p

[Colin Anderson]

Turn down your microphone TX gains on the phones. On my TDM400 with Vista
350's I had to crank the mic value way down. This is not specific to FXS
phones, on my Snom 200's sidetone is so bad, that an appropriate setting for
mic gain is '2' (out of 8)

Hi all,
thanks to the all of you. This list is very interesting also for a newby
like me.
My problem: I just setup my first full working asterisk installation with
this
config:
1. n.1 GXP-2000
2. n.4 Budgetone 102
3. n.1 TDM400p (3 FXS, 1 FXO)

Everything seems to work fine, but the sidetone... it's really annoying!
We can hear the sidetone only when we call to the outside (PSTN), it doesn't
matter if we call a local, a mobile or a longdistance call. Only we hear the
echo, not the called party. We do not ear any echo in internal call to each
other extensions.
I tryed every possible setting of the echotraining, of the rx and of the tx
gain, but with no success.
Any idea or help?
Thank you in advance,
Marco
