Hi fellow asterisk users, I am running Asterisk 1.4.29 with an Digium TE121 card (wcte12xp kernel module) an approx. 100 snom320. The whole installation is running without issues since 5 months.
Without having changed anything on the asterisk server for at least 2 months, i noticed "clicking sounds" at external calls over the PRI. Asterisk constantly throws the following messages: ...

At first (last week) there where only a few of these messages per minute, but today their intervall inceased dramatically. The "clicking" also increased. Can this be caused by problems of the telco (Deutsche Telekom)? If so, could anybody please provide some additional information about it? Does anybody have any experiences with this issue? For sake of completeness i have included the relevant .conf files, but i highly doubt it's a configuration issue: --- cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 CPU6 CPU7 0: 63 0 0 0 0 0 0 1 IO-APIC-edge timer 1: 0 0 0 0 0 0 0 8 IO-APIC-edge i8042 6: 0 0 0 0 0 0 0 2 IO-APIC-edge floppy 7: 1 0 0 0 0 0 0 0 IO-APIC-edge 8: 0 0 0 0 0 0 0 19 IO-APIC-edge rtc0 9: 0 0 0 0 0 0 0 0 IO-APIC-fasteoi acpi 12: 0 0 0 0 0 0 0 105 IO-APIC-edge i8042 14: 0 0 0 0 0 0 0 76 IO-APIC-edge ide0 18: 0 0 1 2922 0 150 648815 506811268 IO-APIC-fasteoi wcte12xp0 19: 0 0 0 153 0 7 4563 285489 IO-APIC-fasteoi arcmsr 20: 0 0 0 0 0 0 0 0 IO-APIC-fasteoi sata_nv 21: 0 0 0 0 0 0 0 0 IO-APIC-fasteoi sata_nv 22: 0 0 0 0 0 0 0 0 IO-APIC-fasteoi ohci_hcd:usb2 23: 0 0 0 0 0 0 0 1 IO-APIC-fasteoi ehci_hcd:usb1, sata_nv 219: 0 0 0 86 0 371 2576954 97457996 PCI-MSI-edge eth0 220: 0 0 0 0 0 0 0 0 PCI-MSI-edge aerdrv 221: 0 0 0 0 0 0 0 0 PCI-MSI-edge aerdrv 222: 0 0 0 0 0 0 0 0 PCI-MSI-edge aerdrv 223: 0 0 0 0 0 0 0 0 PCI-MSI-edge aerdrv NMI: 0 0 0 0 0 0 0 0 Non-maskable interrupts LOC: 11726262 1551452 1834726 1534833 2262834 1499777 4073035 39704316 Local timer interrupts RES: 858017 180201 132730 205234 129387 128549 688861 667641 Rescheduling interrupts CAL: 166 206 221 214 208 213 187 126 function call interrupts TLB: 13298 4915 2847 3680 10646 1067 14320 9156 TLB shootdowns TRM: 0 0 0 0 0 0 0 0 Thermal event interrupts SPU: 0 0 0 0 0 0 0 0 Spurious interrupts ERR: 1 MIS: 0 --- cat /etc/dahdi/system.conf: # Autogenerated by /usr/sbin/dahdi_genconf on Wed Nov 4 13:37:30 2009 # If you edit this file and execute /usr/sbin/dahdi_genconf again, # your manual changes will be LOST. # Dahdi Configuration File # # This file is parsed by the Dahdi Configurator, dahdi_cfg # # Span 1: WCT1/0 "Wildcard TE121 Card 0" (MASTER) span=1,1,0,ccs,hdb3,crc4 # termtype: te bchan=1-15,17-31 dchan=16 echocanceller=mg2,1-15,17-31 # echocanceller=no # Global data loadzone = de defaultzone = de --- cat /etc/asterisk/dahdi-channels.conf: ; Autogenerated by /usr/sbin/dahdi_genconf on Wed Nov 4 13:37:30 2009 ; If you edit this file and execute /usr/sbin/dahdi_genconf again, ; your manual changes will be LOST. ; Dahdi Channels Configurations (chan_dahdi.conf) ; ; This is not intended to be a complete chan_dahdi.conf.
