[asterisk-users] Call signalling on BT FeatureLine Compact (Sangoma A200)

[Paul Goodyear]

Hi,

I have a TrixBox install with a Sangoma A200 and 4 FXO ports, there
are 3 BT lines connected directly to these ports.

One of the lines has BT FeatureLine Compact and this is the line I am
having problems with, the other 2 lines are working perfectly,
detecting CID, answering incoming calls and placing external calls via
SIP devices.

I am receiving a error log entry:

chan_zap.c: Ring/Off-hook in strange state 6 on channel 1

Incoming calls are detected by asterisk, however answering the SIP
devices does not answer the call, and placing a call via line one does
nothing, just silence.

I contacted BT about it (I know, what was I expecting!) they informed
me that I must use the number 9 to access a external number! I have
asked them to pass it to the technical department to see if they have
any input.

Is there someother signalling I should be using to detect the incoming
calls on a BT FeatureLine? I have tried Groudstart but asterisk fails
to load chan_zap due to:

Mar 18 14:01:26 ERROR[28951] chan_zap.c: Signalling requested on
channel 1 is FXS Groundstart but line is in FXS Kewlstart signalling
Mar 18 14:01:26 ERROR[28951] chan_zap.c: Unable to register channel '1'

Any help, or ideas on what to try?

Thanks
