I'm new to *, but I've dealt with this issue on other switches. It sounds like either you are timing out getting DNIS information from your CO, or you are having trouble hearing the DTMF tones that are pulsed to you during the call setup process. Someone else on the list may know: is it possible to 1) configure the timeout for waiting on DNIS and 2) is it possible to change the Rx gain on the TDM cards? It's my understanding that the circuit is going throught the channel bank, which is acting like a drop-and-insert CSU by forwarding the 12 channels with voice to your * box. You mentioned that this was a Carrier Access channel bank, is it an ADIT 600? There are send and recieve gain settings on the channel bank unit that you might want to play with. HTH, HAND -Tim

Subject: [Asterisk-Users] Help! Problems talking to upstream
switch
Hi,
Please let me know if you have any ideas - I am taking
wild guesses now....
Here is the situation:
I put in Asterisk for a local customer. I have
Fractional T-1 with 12
Voice & 12 Data. I have a T100P hooked up to a TDM Card (they
call it a
chanel bank although it only has 2 outputs) in a CAC unit. The
unit also
has a router card that runs the data side. My extensions are
all SIP phones
save a few fax machines. The customer has 7 digit unverified
account codes
on the trunks for billing purposes.
The Problem:
As I watch the console, I see calls coming in for exten
"73" or "708" or
"08" or "730" although most come in correctly (ie "7308"). My
carrier has
verified numerous times that they are sending 4 digits. I have
40 DID
numbers that need to be routed and they are all in the 73xx
range. I need
to know anything that would cause my box randomly not to hear
all 4 digits
on occasion. Also, I have had trouble with people who dial out
getting a
congestion signal mainly on Long Distance numbers. The person
would dial
the number 4 or 5 times and get congestion then it might go
through. Both
of these conditions seem to be happening only about 10-20% of
the time.
What I have done:
Moved a T100P card to its own IRQ to prevent problems with
interrupts - Did
not solve either issue.
On the second try, got the carrier to change the way their
switch chooses
channels for incoming calls to prevent "glare" - This MAY have
fixed the
outgoing long distance issue as it seems to have gone away(
although it
doesn't seem logical to me that this would affect only LD) but
did not fix
incoming calls.
Has anyone else had problems getting all of the digits that the
Telco sends?
Thanks,
Andy Hester
