[asterisk-users] ISDN, overlap and open dialing plans (Olivier)
Dear Oliver
Well I never knew PBX could according to numbers pattern length use enbloc and
overlap, from my experiences dialling mode setting should be one or other, but
it should be set on whole system one mode, by the way if number length pattern
is variable component to use overlap mode.
Just in case when it use enbloc PBX send whole number, TDM phones it press #
or other key setting as send digits.
By the other way check dialplan rules to resolve receiving number length, a good
practice is use and Asterisk extension to simulated call from PBX system.
Best regards

Hi,
I've got the following setup:
PSTN/ISDN <---- E1-----> Asterisk <---- E1-----> Alcatel 4400 PBX
<----> TDM phones
When a TDM phone is dialing out to a national number, it seems that
the PBX is using enbloc dialing.
When a TDM phone is dialing out to an international number (variable
length numbers), it seems that the PBX is using overlap dialing as
Asterisk is currently receiving truncated numbers.
What is the best way to deal with such situations ?
1. configure PSTN in enbloc dialing and tweak dialplan to mimic
overlap dialing ?
2. or configure both PTSN and PBX spans in overlap mode ?
Suggestions ?
Regards

I searched the internet but could not yet find a solution.
I already tried to exchange the zaphfc drivers as suggested, but they did not
compile.
I actually did not find a new(er) tutorial how to build an Asterisk with a HFC-S

Any suggestions / hints / tutorials / links welcome.
Do I need some special drivers in the kernel ?
Modprobe ?
Anything else special I need ?
Thanks

Hi Steve
Thanks for your input. Please check my comments.

What kind of capacity are you looking to achieve?
[Amit Patkar] Some where 2400 G.711 sessions with recording. So approx 1200
calls.
>From my experience, Asterisk is not really much of a RAM hog. A couple

is good for a couple hundred simultaneous calls.
With 4 'Intel(R) Xeon(TM) CPU 3.40GHz' cores, I can handle a couple
hundred
simultaneous non-transcoding calls with no recording on Asterisk 1.2.
With 24 cores and 16 GB on tap, you will probably find other resource
limitations before either CPU or RAM are a limiting factor.
Personally, I'm a 'don't put all your eggs in one basket' kind
of guy.
Assuming a simplistic linear relationship between my host and yours, what
will you do when it crashes with 1600 calls in progress? What will you do
when you need to install patches or upgrade or ...
I like a couple of instances of OpenSIPS in front of several Asterisk
instances, even if OpenSIPS is on the same boxes as Asterisk.
[Amit Patkar] I completely agree with you on distributing the load. At the
same time, I am looking at juicing hardware as well. Can you share the
number instead of saying couple hundreds?
> What will be impact on no of session when G729a is used?
Significant.
[Amit Patkar] Can I assume 30% reduction? Or it would be much more.

This means the config file says 3 ports, but no card is detected.

Hi Kevin,
Thank for your views. Where as no one is ready to share real numbers. I am
looking at benchmarks so that I can plan for resources.
Since asterisk project is active for so many years, I was expecting some
published numbers.
Thanks & Regards,
Amit Patkar

Assuming that transcoding is involved; if all the system is doing is
passing through G.729A media streams, and recording them in unmixed
G.729A format, there's no additional impact (the system might actually
perform slightly better, as there is substantially less data being
shuffled around).

This will not help. Assuming we are talking about a SIP REGISTER here,
the password is *not* sent in the request. Asterisk issues a challenge
including a randomly generated value (called a 'nonce'), then the UA
attempting to register responds to that challenge with an MD5 digest of
a string composed of various elements, including both the nonce and the
shared secret ('password'). Asterisk computes the same digest
internally, and if they match, then the assumption is that both ends
know the shared secret.
By their very nature, digest functions are not reversible; given the MD5
digest present in an SIP request containing an Authorization header,
there is no way to figure out what shared secret was used in the
computation of that digest. Since you know the nonce and the other
portions of the calculation, you could attempt to try various 'likely'
passwords to see if any of them result in the same digest value... this
is called the brute-force method, and it could take a *very* long time
to arrive at a shared secret that would allow the endpoint to register.

Looks like you may need to blacklist hfcpci in
/etc/modprobe.d/blacklist.conf.

You have completely missed the point that other posters have made
already on this list. Let me try to express it another way. Let's say
that you were browsing at an engine manufacturer's website, looking at
V-8 gasoline engines, and you found one that you liked, that you felt
had a good combination of features for your project. If you then
contacted the manufacturer and asked them 'how fast can this engine make
a car travel', what do you think their response would be?
Asterisk is a toolkit; it can be configured an infinite number of ways.
Any performance measurements that are made and published apply *only* to
the specific configuration that was measured; it may or may not be
possible to extrapolate those into other configurations, or higher/lower
capacities.
There are lots of published numbers of Asterisk being used in various
ways and for different purposes; whether any of them apply to your
specific project is debatable, and relying on them for your project
would carry some level of risk. Whether you are willing to accept that
risk or not is up to you.
In your specific case, as has been mentioned already, it is extremely
unlikely that your proposed hardware would have any trouble with
Asterisk 1.8 handling 2,400 SIP call legs (1,200 bridged calls), with
the same codec being used on both sides. When you add in transcoding,
that will change the system significantly, and depending on the codecs
involved, the hardware may still be able to handle the load. I know from
experiments I did years ago with an 8-core Xeon machine (2nd generation
Xeon, so nowhere near as powerful as modern Xeon cores) that the Digium
G.729 codec (software implementation) could handle over 800 channels
with Asterisk 1.4; I think it's reasonable to expect that given the
hardware you've proposed, transcoding 1,200 channels between G.711 ulaw
and G.729A is likely to be achievable.
Recording, though, is an entirely different matter. Again, since you
haven't provided specifics, let's assume you are going to record the
call legs 'as is' (in their native formats, unmixed). If you had 2,400
G.711 ulaw call legs to record, some simple math says that you'd need be
able to push 150 megabytes per second of data onto your filesystem, on
top of all the 'normal' work that Asterisk is doing. That's rather a
lot, and will require that your filesystem and disk subsystem be
extremely fast and well tuned.
If the call legs were all G.729A, then the amount of data to write would
drop to 18.75 megabytes per second, which is achievable even with
inexpensive SATA disks.
If you want the calls recorded in 'mixed' form (most likely in 16-bit
signed linear PCM audio, since that's the easiest format to use outside
of Asterisk), you'd double the amount of data going into the filesystem
(now 300 megabytes per second) *and* you'd add in the CPU consumption of
having to decode the incoming media streams and mix them. For G.711 ulaw
this is pretty cheap and would likely not be an issue; for G.729A it's
somewhat more expensive, but still might not be a problem given the
amount of CPU capacity you have proposed.
Now do you understand why 'benchmarks' don't provide much value for
something like Asterisk?

http://updates.xorcom.com/pkg-voip/ has some Squeeze backports. Though
they're not kept up-to-date all the time. They include zaphfc.

You should probably blacklist hfcpci.
echo 'blacklist hfcpci' >>/etc/modprobe.d/WHATEVER.conf
(Replace WHATEVER with whatever name). Then run 'rmmod hfcpci' once to
remove that module at this time.

OSLEC ist planned in the future. I fist have to find where to get the sources
and howto compile / load them. Hints appreciated.
First wanted to get basics running.

lsdahdi returns nothing, while
lspci
00:0d.0 Network controller: Cologne Chip Designs GmbH ISDN network controller
[HFC-PCI] (rev 02
and
dahdi_hardware
pci:0000:00:0d.0 zaphfc- 1397:2bd0 HFC-S ISDN BRI card
I would have expected dahdi_hardware would be closer related to all dahdi
commands.

Thanks, but here I don't have any experience how / where to attach these
patches. Where can I find more info about it ?

Removed and blacklisted with echo 'blacklist hfcpci'
>>/etc/modprobe.d/blacklist.conf
Already blacklisted for unknown reasons:
blacklist hfcmulti
blacklist hfc4s8s_l1
blacklist wcb4xxp
Don't I need all /one of these modules ?
Probably not the hfc.. ?
Thanks

Thanks will give that a try.
p.s.
i know the method, only problem that its a time consuming process (in
this case it includes a 9000 km travel and not all equipment on that
