asterisk users - Nov 2003 - Picking an open channel (FXO port) for outbound calls

Greetings:

I did some quick searching of my history of this list, and I tried a quick
Google search as well, but perhaps someone on the list can quickly answer
this question.  I have a very nicely working Asterisk system at home with
two Digium X100P FXO cards.  When my SIP phones want to dial-out I have them
setup to grab the first analog card (Zap/1) with the following
extensions.conf segment:

==== snippet ===
; Outbound
exten => _9.,1,Dial(Zap/1/${EXTEN:1},90,Tt)
exten => _9.,2,Macro(fastbusy)
exten => _9.,102,Macro(fastbusy)

==== /snippet ===
Zap/1 and Zap/2 are analog phone lines.  What is the best method of picking
an open line when someone tries to dial-out? i.e. if Zap/1 is in use how can
I instruct Asterisk to use Zap/2 and vice versa? I know complex methods of
making this happen, but I'm sure there is a very simple way to accomplish
this task.

Thanks.

I think the generally accepted method of this is using groups.  Assign
both lines to a single group, then dial out using the group instead of
interface.  I believe it's in zapata.conf.

I hope this gets you pointed in the right direction,

Use the `group` syntax for the Dial command, ie:

exten => _9.,1,Dial(Zap/g1/${EXTEN:1},90,Tt)
                        ^

And in your zapata.conf put:

group = 1

before the device declaration of Zap/1 and Zap/2.

hi.
use groups :)

zapata.conf
group=1
signalling=blah
channel=1-2
etc etc

then in extension.conf, just use
exten => _9.,1,Dial(Zap/g1/${EXTEN:1},90,Tt)

or better, add in globals section
TRUNK=Zap/g1

and
exten => _9.,1,Dial(Zap/${TRUNK}/${EXTEN:1},90,Tt)
in outbound context

Dial(Zap/g1/....

As long as they are in the same group asterisk will pick an unused card.

Setup groups

In your zapata.conf do group=1 before your channels => line.

then Dial(Zap/g1/blah)

  -= Info about application 'ChanIsAvail' =- 

[Synopsis]:
  Check if channel is available

[Description]:
  ChanIsAvail(Technology/resource[&Technology2/resource2...]): 
Checks is any of the requested channels are available.  If none
of the requested channels are available the new priority will
be n+101 (unless such a priority does not exist, in which case
ChanIsAvail will return -1.  If any of the requested channels
are available, the next priority will be n+1, the channel variable
${AVAILCHAN} will be set to the name of the available channel and
the ChanIsAvail app will return 0.

as in:

exten => _9.,1,ChanIsAvail(Zap/1&Zap/2)
exten => _9.,2,Dial(${AVAILCHAN})
exten => _9.,102,NoOp
exten => _9.,103,Congestion

(Note that specifying a timeout in the Dial application
with FXO ports doesn't really do anything -- the channel
is considered 'answered' as soon as the call is placed
regardless of whether the remote end answers)

Try putting the channels in a group (IIRC just put a group=>1 in
zapata.conf before channel=> lines - I don't own any Digium hardware
though :( ) and replace Zap/1/ with Zap/g1/

Works for me with 2x Fritz PCI cards (i4l, as it mostly works and if
it ain't broken, don't fix it.. capi is on my schedule though..)

HTH,

Tony,

In the [channels] section of Zapata.conf, create a group => 1 (or some
value), followed by the two FXO port definitions. Now change the Dial
string to Zap/g1 (where g1 is group 1, etc). A small 'g' will grab the
first available port and work upwards (i.e., Zap/1 the Zap/2, etc.).
While a capital G will do the same, but from highest defined port to
lowest.

Definitely in the wiki and Digium docs. :)

or
exten => _9.,1,Dial(Zap/G1/${EXTEN:1},90,Tt) ;search first open zap in
decending order

asuming in zapata.conf you have
group=1

b4 the
channel=1-2 stmts

However, beware that if you have any analog phones on those two lines,
* will not detect whether they are in use and will dial over the top
of any existing conversation. * does not sense dialtone, etc.

Rich

first you would set up a group in zapata.conf
  [channels]
  signalling=fxs_ks
  group=1
  channel=1-2


then in your extensions.conf file replace your dial
line with this:
  exten => _9.,1,Dial(Zap/g1/${EXTEN:1},90,Tt)

..Hope this helps...jak
