I am working with Digium support on this issue [ card intermitently stops passing calls]], but wanted to tap into the community to see if perhaps anyone else has come across this issue or has any ideas how to fix.
Problem: Dahdi starts off capabale of detecting, answering and making phone calls, no issues then after some unknown event dahdi stops recognizing calls at all … unable to place calls. Restarting/reloading Dahdi fails and ampotal restart in FreePBX does not fix it. At one point there was even a kernel panic and the server had to be powered off manually.
What I am using:
Dell Poweredge 210 II / Intel i3 / 2GB ram
DAHDI Version: 2.6.0 Echo Canceller: HWEC, MG2 (PCIe)
Linux version 2.6.18-274.3.1.el5 (gcc version 4.1.2 20080704 (Red Hat 4.1.2-51)) #1 SMP Tue Sep 6 20:14:03 EDT 2011
Digium support also modified and added to file:
options wctdm24xxp fxovoltage=1
Not enough info? just ask and I will pull any info you need. I will try anything at this point… kinda frustrating.
