Hello All,
Please let me know if you have any comments or suggestions how to resolve the following situation. My configuration is:
- Dell PowerEdge 1750 (standard), one CPU Xeon 3.0GHz
- TDM400P with 4 FXO, connected to 4 regular phone lines (PSTN)
- Asterisk 1.0.0 from cvs
- Zaptel and Zapata latest from cvs
- Debian 3.0 Woodoo / compiled kernel 2.4.27
Initially Asterisk works fine for a few hours, hard and soft phones are able to dial out and receive calls from outside. In about 6-8 hours, when I would try to dial out from any extension through Zap/1 ... Zap/4 (I have group #1 defined) I would hear continuous loud noise for 20 seconds - then silence. Call stays connected but apparently TDM400P is not even picks up the line to dial. No sounds could be heard after that. Repeat dials for any number of times - same thing.
What would fix this: either restart of the whole server or shutdown asterisk, then rmmod wctdm; rmmod zaptel; modprobe wctdm. Though, in a few hours after modules are restarted I have the same situation - loud noise on dial out and no rings detected on inbound calls.
BTW, when on wctdm module load NMI would always occur, though the server and card works fine after that:
Module 0: Installed -- AUTO FXO (FCC mode) Uhhuh. NMI received. Dazed and confused, but trying to continue
You probably have a hardware problem with your RAM chips Module 1: Installed -- AUTO FXO (FCC mode) Module 2: Installed -- AUTO FXO (FCC mode) Module 3: Installed -- AUTO FXO (FCC mode) Found a Wildcard TDM: Wildcard TDM400P REV E/F (4 modules) Registered tone zone 0 (United States / North America) Registered tone zone 0 (United States / North America)
Here is some more information about the server:
# cat /proc/interrupts CPU0 CPU1 0: 781301 0 IO-APIC-edge timer 1: 6 0 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 15: 5 0 IO-APIC-edge ide1 16: 311577 0 IO-APIC-level eth0 17: 86308 0 IO-APIC-level eth1 18: 11391 0 IO-APIC-level megaraid 20: 7797642 0 IO-APIC-level wctdm NMI: 1 0 LOC: 781160 781115 ERR: 0 MIS: 0
So it is not interrupts problem. Tried to move Digium card in a different PCI slot (#2 now) and changing IRQ in Bios, loaded the kernel with pci=noacpi, and nothing would help.

Please help! I would appreciate any comments or suggestions. zaptel.conf and zapata.conf are standard taken from samples on voip-info.org for card with 4 FXOs.
Sincerely, Andrei
