I am in the process of setting up an asterisk server to replace our old norstar system. Just need to test it first before we go live with it.
It P4 2.4ghz pc with fc3 and asterisk,libpri and zaptel 1.2
I have setup 4 eyebeam ver(1.1 3004w) sip softphones on extensions.
The box is connected to a Bt Uk Analogue line using a Digium tdm400p with 1 fxo card. In the future we will get a card to link to isdn30
Everything seems to work except people who are testing is are keep
saying the voices sound muffled on outgoing and incomming calls via the bt line. Even tried it with different headsets.
Eyebeam shows gsm codec.
I have the rxgain =10.5 and txgain=4.5
What and where should I look for this problem. ?
