[asterisk-users] DAHDI not detecting RINGING Status on the Channel

Mon Oct 26 19:02:10 CDT 2009

For some reason I am not able to set loopstart instead of kewlstart:

Console out put:

[Oct 26 20:58:40]   == Parsing '/etc/asterisk/chan_dahdi.conf': [Oct 26
20:58:40] Found
[Oct 26 20:58:40]     -- Registered channel 1, FXS Loopstart signalling
[Oct 26 20:58:40]     -- Registered channel 2, FXS Loopstart signalling
[Oct 26 20:58:40] ERROR[23050]: chan_dahdi.c:7677 mkintf: Signalling
requested on channel 3 is FXS Loopstart but line is in FXS Kewlstart
signalling
[Oct 26 20:58:40] ERROR[23050]: chan_dahdi.c:11294 build_channels: Unable to
register channel '1-8'
pbx*CLI> module load chan_dahdi.so

any ideas? I am still tring to set some other parameters like:

cidsignalling=
cidstart=

Thanks
