I've recently installed Asterisk-based servers at several of our branch
offices. Each server has 2 X100P cards to handle 2 incoming voice
lines. I was having a lot of trouble with Echo until I got OSLEC
running on all of the servers, but now we have a new problem. Incoming
callers are not always able to dial extensions. I would say probably
95% of the calls go through correctly, but that other 5% always get
dumped to the operator queue. I have relaxdtmf=yes in my zapata.conf
for both channels, but it doesn't always help. One particular customer
has trouble dialing an extension about 1 call in 5. I'm wondering if
it's just because they call us more than any of our other customers or
if there is some peculiarity with their phone system. Anybody have any
ideas what to try next?

Thanks,
Brent Davidson

Hi Brent;

I have been suffering from this problem since about 2
monthes and until now still did not resolved 100%.

First of all, I need to tell u that mostly u have a
problem that the first digit is duplicated, for
example: if ur customer entered 108 then it will be
recognized 110 (the 1 duplicated, and then it takes
the 0, and it does not continue to take the 8 as it
completes the 3 digits ... this is just an example).

Your problem is in the duplication for the digit and
specifically the first digit usually will be
duplicated.

If u found a solution let me know.

Regards
Bilal

Lower the rxgain and txgain on your Zap channels.

I was having the digit duplication early on, but turning the relaxdtmf
option on and X Windows off solved the duplication problem. I have
logging turned up extremely high and there are no digits detected on the
calls that are unable to dial an extension. The way I have my dial plan
set up dialing an extension that does not exist sends the user to an
"Invalid Extension" message then returns them to the main menu. When a
caller has issues with the DTMF the logs show that the WaitExten timed
out with no digits dialed.

Thanks,
Brent

I have seen too high of audio levels cause echo. It can also distort
the audio. I imagine either of which I imagine the system can detect as
a doubled digit. When I experienced this on some lines in Glufport, MS,
random digits were doubled. He's tried everything else.
