Hi,

has anyone got a configuration for connecting a TE412p to a BT ISDN30 using Zap? If so could I have a copy?

Thanks

Best Regards

Geoff

Would the configuration be similar to the TE110P ? If so then many examples can be found online/the forum.

Yes it would be the same configuration except the kernel driver is called something else.

Hello,

Your zaptel.conf should look like this.

span=1,1,1,ccs,hdb3,crc4

bchan=1-15
dchan=16
bchan=17-31


loadzone=uk
defaultzone=uk

and zapata.conf should look somethink like…

[channels]
language=en
usecallerid=yes
hidecallerid=no
callwaiting=no
callwaitingcallerid=yes
restrictcid=no
usecallingpres=no
threewaycalling=yes
callreturn=yes
transfer=yes
cancallforward=yes
echocancelwhenbridged=yes
echocancel=yes
musiconhold=default
rxgain=0.0
txgain=0.0
signalling=pri_cpe
switchtype=euroisdn
switchtype=euroisdn
immediate=no
overlapdial=yes
pridialplan=unknown
prilocaldialplan=unknown
group=1
context=inbound
callerid=asreceived
channel => 1-8

You will have to change the number of channels (ie channel=8 ) based on the number of active channels.

Hope this helps.

angler, rosco - thank you both very much. I’m moving to a new office with ISDN soon and the isdn config is/was the biggest unknown variable.

Hi,

I have also just got my UK BT isdn30 line linked to asterisk via a digum card in the last week. My zapata.conf config is almost the same except for.

echotraining=yes

Also

I have caller ID enabled on my line or thats what BT have told me twice when I have checked but cannot get caller id to work. I have the following line on my incoming which works for 6 analogue lines I also have on the box.

exten => s,1,Verbose(Incoming call from BT – CallerID=${CALLERID})

For the analogue lines I had to use the following in zapata.conf as BT use a diffrent system for callerid.

usecallerid=yes
immediate=no ;dont take line on first ring
callerid=asreceived ; propagate cid as received from bt
cidsignalling=v23 ; Uk callerid setting for analogue
cidstart=polarity

What do i need for caller id on isdn30 ?.

Thanks if anyone can give some help on this.

Hi Nickcol,

The config I posted above will provide you with incoming CLI detection (at least it works on all the BT ISDN30 installs I’ve done!).

Try using the variable ${CALLERIDNUM} in your verbose statement and see how you get on with that.

Rosco.
