asterisk users - Feb 2005 - defining the zap channel used on inbound analogue calls

Hello all

I am relatively new to asterisk and am sure this will be a simple question
to answer. I have a TDM400p card and I am in the process of creating my dial
plan, however I am a bit stuck on one thing. I have 2 analogue lines (each
obviously with its own DDI) connected to the card; I want to set it up so
that if I dial inbound to the first DDI (e.g. 02087775555) it will go to the
IVR and when I ring inbound to the second DDI (e.g. 02087776666) I want it
to go directly to the SIP phone internally. Its with the latter I am having
the issue 

My problem is this .... Due to the fact these are analogue lines, I realise
that the DDI is not sent to the TDM400P so I presume the only way for the
dial plan to filter inbound calls is by the Zap Channel it came in on? (In
my case Zap/1 and Zap/2). I have tried the following

------
[globals]

INBOUND=Zap/2

[default]

exten => ${INBOUND},1,Answer
exten => ${INBOUND},2,Background(soundfile),tT
exten => ${INBOUND},3,Hangup

------
I also tried 
exten => Zap/2,1,Answer

And

exten => Zap/2-1,1,Answer

And various other combinations all to no avail, is it possible to filter by
the Zap channel used ?, Surely if I want to direct call a phone, I don?t
have to go through an IVR everytime ?? (I realise this wouldn?t be an issue
with ISDN).
 
I noticed also in some documentation that you have to use an ?s? for all
analogue traffic, is this the case ?? and if so can you use it in
conjunction with a zap channel definition ??

So in summary, How does the dialplan define the Zap channel used on inbound
analogue calls

Any help would be greatly appreciated

Try using a different context for each incoming channel in 
the zapata.conf. An example is below, except I have one 
FXO and one FXS. But the concept is the same.

[channels]

context=analog
signalling=fxo_ks
echocancel=yes
echocancelwhenbridged=yes
echotraining=800
relaxdtmf=yes
rxgain=0.0
txgain=5.0
busydetect=yes
callprogress=yes
usecallerid=yes
callwaiting=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
callreturn=yes
cancallforward=yes
adsi=yes
mailbox = 2000
faxdetect=incoming
channel => 1

context = fromPSTN
signalling=fxs_ks
rxgain=5.0
txgain=0.0
channel => 4

If I got you question, I think you can resolve your problem by separating your 
incoming channels to particular contexts.


zapata.conf
....
context = line1
channel => 1
....
context = line2
channel => 2
....

extension.conf
....
[line1]
exten => s,1,Answer
exten => s,2,Whatever(YouWant1)

.....
[line2]
exten => s,1,Answer
exten => s,2,TheOtherThing(YouWant2)


This way, calls coming in from line 1 will execute Whatever(YouWant1), and 
incoming in line 2 will execute TheOtherThing(YouWant2).
