Disconnection supervision: what about PBX
After reading through several recent threads, I started to wonder why the
Cisco document (and other VoIP documents) appears to present this issue as
VoIP gateway specific. Don't (plain old) PBX' face the same issue if they
use analogue interfaces? If there are analogue PBX' at all, how do they
solve the problem?

Integration between Asterisk and Siemens HiCom 150e over ISDN
Hi,
I am looking to integrate Asterisk with a Siemens HiCom 150e via BRI and
wondered if anyone is able to offer any advice.
In simplistic terms, my goal is to pass calls from the HiCom to the Asterisk
box. e.g: HiCom user dials access code and can call Asterisk extension or
establish SIP call over Internet. Likewise, I'd like Asterisk to be able to
present a call to the Hicom, either

Asterisk, VoIP and Samsung iDCS100
Hi,
Firstly, I'm new to Asterisk and am a system admin rather than a phone engineer. I've googled and read around but haven't been able to answer my questions sufficiently to buy hardware and get this thing set up.
Secondly, if I've missed vital information from what is below, please let me know what.

Cisco SIP Gateway
Is anyone using a cisco router as an ISDN gateway with Asterisk?
As you might have seen from a couple of my threads, I have been looking at
Fritz! and Cologne cards, both of which require development against a
specific version of asterisk/zaptel (e.g. chan_capi), which is intrusdive
and causes a lag in deployment.
I was thinking a better approach might be to use a seperate gateway, such as

Spa3k and ISDN
Hello all,
I have an ISDN termination box (TR1) that converts ISDN(Bri) to 2 normal
analogue lines. The same number is assigned to these lines. These lines are
connected to 2 spa3k registered to my asterisk box.
When calls arrive, TR1 try to pass call to the first spa. If spa not takes
the call immediately then try to pass to the other spa. The only
configuration I found works is to put the

Send flash through zap channel
Hi everyone,
our setup includes a NEC PBX connected to our asterisk via bri lines.
The NEC has a doorphone feature, which is just an extension that calls you when someone rings. When connected to this extensions, a 'flash' signalling opens the door.
So now, i'd like to trigger this from asterisk, too, but unfortunately wasn't able to do so.

Echo on PRI/BRI?
Howdy:
Does echo only occur on analogue PSTN lines, or can it also occur on PRI and
BRI lines? If so, for the same reasons? This is a part of our consideration
to transition to BRI.

Howto use PRI lines (E1 or T1) for "data calls"?
Hi,
I'm looking for a mean to send digital data over
an E1 line, just like isdn4linux or Capi via AVM's FritzCard
is able to do it with BRI lines (e.g. for PPP or ISDN raw
connections).
I'm not looking for modulated audio data representing
digital data, like fax or the analogue modems of former
times. I want an interface to the ISDN raw data, with
an outgoing call marked as

Monitoring Sirrix quad BRI channels
Hi all,
How are things going ?
Is there a way for me to individually identify each BRI channel on the Sirrix quad BRI board.
The reason I ask is because our client uses the "Asterisk Flash Operator Panel" to monitor its external lines and transfer calls from the lines to the various SIP phones.
The "Flash Operator Panel" requires that we set a static value for each line or

UK X100P installation help
Hi,
I've got the latest asterisk@home setup running with SIP. I've been
trying to tie it in with the PSTN off and on for a while with no
success. I gave up on ISDN and purchased 2 x100p cards from x100p.com.
I've got the card installed, the machine can see it.
The problems I have at the moment are
First time I start up the drivers and asterisk, I can call the pstn

asterisk and pstn
Hi,
First of all apologies because this isn't strictly a purely asterisk
question.
I am quite new to asterisk and actually to voip/telephony as a whole.
I currently have sip calls working through asterisk. The asterisk
server is behind a linksys router. I would now like to connect calls
to the pstn. I have researched into several ways to do this but
because I am not very knowledgeable about

DAHDI and Analogue lines (UK)
Have an intersting issue whem migrating a site from Zap on 1.3 to DAHDI on
1.4.. Nothing special about the hardware - older TDM400 card, 2 red
modules fitted...
Both channels work fine under 1.2/Zaptel. With 1.4/DAHDI both channels
still work OK, but only for one line - the 2nd line causes it to refuse to
dial-out no matter which port it's plugged into.
The Lines are bog-standard BT

receiving fax with junghanns quadbri bristuff
Hey,
anyone know if it's possible to receive faxes through a Junghanns bristuff
quadbri card?
In germany, currently I have faxes coming in on DID line into QuadBRI and
then passing to Digium TDM400 (analog) and into faxmachine. But the
reliability of TDM card is spotty, so I want to maybe just accept faxes in
on ISDN card and save on asterisk system ...? keeping digital signal strong

isdn, modem, etc.
I see many posts about using ISDN cards and modem cards.
Does this mean I can use a regular modem (that supports voice) as an
FXS, or FXO ?
If so, can you provide an example.
It might be the easiest way to test Asterisk's collaboration with the
PSTN (or analog phones) and provide proof of concept to non-believers.
Thanks.

Minimum Setup
Hi all, I have asterisk installed and working just fine with a couple of Cisco IP Phones. I am now ready to pilot connectivity to PSTN and am wondering what hardware would be recommended to make minimum connectivity to the public telephone network. I am think ISDN as I would like a few external lines to be accessible.

Oz ISDN
In Australia, Telstra, the local telco provides isdn modem for isdn
connection. The modem has 2 analogue telephone jacks and a serial port
for connection to dialup internet.
My question is that will it be possible to use Zaptel TDM02B to connect
to the analogue jack instead of getting a fritz card to do the
telephony. Will there be less feature if doing so?

best ISDN BRI solution for DID
I want to test asterisk with its DID functions on a smaller scale without the expense of a PRI. I am in the US, and want the most reliable/stable, and feature rich solution that I can have.
What ISDN card would be reccommended?
My clec switch operator says he can/will send DID info to my BRI's if I wish. Can Asterisk, or one of its addons support this?

Capi channel - can I route call to another channel or back to PBX and free current channel ?
Hi,
I have following problem. Asterisk is connected to ISDN router on BRI
interface. ISDN PBX is connected to another channel of BRI interface. Now
I'd like to route all incoming calls first to Asterisk and then if caller
wants to talk to extension on ISDN PBX then I'd like to route call to
another capi channel but free the current one.
Is this possible at all or do I need to take 2 capi
