asterisk users - Mar 2008 - Intermittent DTMF Problems

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
