auto-gain, or different gain between incoming and outgoing calls (EURO ISDN PRI) ?
Hi,
I am using Asterisk with various brands and models of SIP phones. Especially
the Welltech phones LP201 are particularly nasty with volume and echo. Even
with the input gain (microphone) of the Welltech set to the max, the PSTN
end can hardly hear the SIP user on incoming calls. Ztmonitor also only
gives a level of around 3 === from the SIP phone.
I have to increase the rxgain and txgain by about...
