Just to add some info from recent experience. May help, May not 1 X100P 2 X 4 port TDM400P
Had to hook a dial-in palm PDA base for a custom software implementation to my * system and have the modem dial out and work properly. Phone connects to second port on PDA Base Experienced very bad "electrical" type noise on the line, hum, buzz, fad in and out. would come and go. Switched ports, wires, rxgain and txgain changes, phone changes, nothing helped the PDA base is also connected via serial port (or USB did not matter) to desktop computer for sync purposes Through trial and error. Found noise coming from connection to desk top computer. On, Off did not matter. Resolution. The power strip surge protector I was using on the desktop computer has two modes for noise filtration built in. 75 Hertz (or something, don;t remember) and 50 Hertz. I moved the plug for the desktop from the 75 side to the 50 side, All noise on line now gone. Not sure if this helps, constant noise on all sides may be power and noise filtration related... --- "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > Hi All > i have some background noise problem with * and a > diva srv 4bri + chan_capi 0.3.0 + X-Ten PRO on my > pc. > Both in incoming and outgoing call have a background > noise. > > there is some tuning to do? > where can i find documentation about capi.conf? > which is the best codec for sip (ulaw, alaw, > gsm...)? > > mark > > _______________________________________________ > Asterisk-Users mailing list > [EMAIL PROTECTED] > http://lists.digium.com/mailman/listinfo/asterisk-users > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users __________________________________ Do you Yahoo!?
