I have an Asterisk server configured to run as voicemail with a T1 and
SMDI.
It has 1.6.1.6 (dahdi 2.1.0.4) and Centos 5.6 and has worked great for a
few
years. I am configuring a new server with Asterisk 1.8.13 (dahdi 2.6.1) on
Centos 5.8
The problem I am having appears to be related to DTMF detection. When the
test phone number is called (2704083000) Asterisk only receives a portion
of
the dialed number. It varies as to what numbers are detected. Sometimes it
sees a single digit, sometimes 3 or 4 of the digits of the dialed number.
When I compare this to the old server the debug below is similar but there
isn't any mention of the "sig_analog.c" lines shown below.
I am told the T1's on the old server and the new server are configured the
same. I can make outgoing calls on the T1 from Asterisk.
Can someone give me a clue as to what could be causing this?

Try setting:
relaxdtmf=yes
We used to have that same problem on most of our servers. Setting
relaxdtmf to yes solved the problem for us.
