Hi!
I have problems with the ToN configurations in chan_capi-cm. I understand how
incoming calls are rewritten using national and international prefix. But for
outgoing calls - what is the ToN?
I never really needed ton in TE mode, but when your card is in NT mode,
setting the ton may be important.
Further, is there any debug info of the Ton? "capi debug" and the divactrl
dchannel both show the CLI and CDLI, but do not show the ToN.
The ton is a byte prepended to the callerid and can be seen when looking at
the capi messages. On outgoing call when 'capi debug' is set, the
presentation and ton value is shown as well.
Hi Armin!
I think the capi debug is too verbose. When I debug, I'm mostly
interested in D-channel info, not B-channel. What do you think about
splitting this into
"capi debug dchannel" and
"capi debug"
How can I set the ToN? I suspect chan_capi to use the received ToN also for
outgoing calls when bridging calls. How can I verify this?
When using a newer Asterisk with cid_ton (I think 1.2.x has them), then
chan-capi will set ton on incoming call and on outgoing call, this value is
used as well. So it is bridged.
This is IMO a strange thing, combined with the default behavior of
national and internationalprefix.
e.g. a call is received with CLI=4912345 TON=international
default internationalprefix=00
Thus, chan_capi rewrites the number to 004912345, cid_ton is still
international.
When this call is bridged to the PBX, it sends CLI=004912345
TON=international
Thus, if the number is rewritten, IMO also the context should be
rewritten to UNKNOWN.
Since Asterisk does not provide (as far as I know) a possibility to change
that cid_ton value, chan-capi will overwrite that value with the value in
variable ${CALLERTON}, if set.
As I see this must be a number. Using strings (INTERNATIONAL, LOCAL,
NATIONAL) would be nice too.
Not sure if I understand the source code right: CALLERTON will be read
to set callers TON on outgoing calls, whereas CALLEDTON will be set on
incoming called TON? Why not set both variables in incoming calls and
read both variables on outgoing calls?

Klaus
When you use the latest chan-capi from trunk (HEAD version), you can use
'capi show channels' to see the ton as well.
