Re: [asterisk-users] DAHDI DTMF problem?
I used the dahdi_monitor to record the audio on the T1 channel of the working server and the new server. The audio stream of the working server allowed me to hear the audio I heard over the phone call plus the DTMF at the very beginning. The audio of the new server was completely messed up. I could barely make out the where the DTMF and the audio were in the file. If I didn't have a working sample I wouldn't know what it was. And, the beginning of the new server sample always contains a hum or tone in it whereas the working server does not have that. What does this tell me?

Just a shot in the dark, going from my experience with other cards and same symptoms. If the card is new(ish) I would think Digium could provide support to you for determining the DTMF problems. Bill, To repeat what Tim said, if you're eligible I would recommend contacting Digium's support department. There are many variables with a new install and Digium support would be happy to help you troubleshoot. Some other things to try in order to isolate the drivers / hardware change from the Asterisk change. You could: a) Install the exact same versions of Asterisk / DAHDI that you used previously on the new server with Centos 5.8. b) Run a local pattern test to verify the host <-> card communication is valid. If you have problems here there may be a framebuffer configured or a disk controller running in combined mode preventing the cards interrupt handler from running in a timely fashion. c) Use dahdi_monitor to record the audio on the channel you're testing with and open it up with audacity and verify that the DTMF looks correct. If it does, then most likely there is a problem with chan_dahdi reading the audio from the drivers quickly enough. d) Ensure that you are only loading the Asterisk modules you need in case you're running on a system with limited memory and the asterisk process is dropping audio while paging in code.

Sorry, forgot to include that. It has a Digium Wildcard TE122 I've asked Digium about the card below. They say the -1 in the bipolar and CRC errors is ok. They don't change.
