[Asterisk-Users] Channel Bank Woes...

[Brent Franks]

Hello all,

I have a new Carrier Access Adit 600 and am having a problem dialing out
and receiving incoming calls.

After the initial ring, the calling party will here nothing.  There is a
silence, but the SIP phones that is supposed to ring will ring.  The
calling party will not hear the sound of the ring that * sends out on
the line.  Additionally, if someone picks up the receiver there is no
sound, but occasionally you can here something trying to get through
that sounds like tin-foil is over the MIC of the phone.

The Channel bank is grounded properly, and only has one 8 Port FXO card.
Also, there is nothing in any of the PCI slots except the 1 T100P card.

Sometimes calls will work great (it's very sporadic), and everything
sounds really clear.  Sometimes there will be no sound on the line,
others when trying to place an outgoing call the dialtone will sound
like it has a lot of static  I have six phone lines from Verizon and the
problem will occur on all of the phone lines, not just one.  I have
trouble-shooted this thing extensively and have hit a wall.  

I have attached my configurations (zaptel.conf, zapata.conf, and print
config (from the CB)).

Has anyone seen anything like this before?  Any help or other avenues to
try to trouble shoot would be greatly appreciated!

Thanks,

B
