FYI that I have experience the same problem many times.  The system is =
running RH 9.0 with Asterisk CVS-02/21/04.  Here is the output from the =
console:
I am using RH 9.0 too.
If I forget to do the:
export LD_ASSUME_KERNEL=2.4.1
before asterisk is started then it will handle less than 10 calls before it crashes.
Otherwise it seems rockstable in our enviroment with SIP and zaptel TP410P's when it's started

 I know a little history on the 3com SIP phones... We have about a dozen

 of the
 box and had to be upgraded with a new flash image.  I can't recall if 
 they came from
 the factory with H323 or the 3com proprietary IP protocol but the phones 
 look just
 like the 3com PBX phones you see in small businesses.  3com abandoned 
 the phone
 after spinning off the SIP division (Commworks?) and determining that 
 the phone
 hardware just didn't have the resources to continue work on SIP.  It is 
 a shame because
 these phones boot faster than any other IP phone I have seen and have a 
 good speakerphone.
 The image that we use is pre-RFC3261 but would probably work with Asterisk.
 

I have the same phones here (two of them). Got them directly from 3com
in late 2000 I think.

They were never distributed in the channel I think (at least not here
in Europe). Mine arrived SIP ready, and I flashed them once with a
standard TFTP procedure. Unfortunatly, 3com discontinued them, no more
firmware are available, AFAIK. My firmware is 1.0.1.21.0 SIP.

Unfortunatly I'm not able to find this latest firmware on file.

Note that the hardware is probably not the same as the standard NBX
phones : my SIP phones did feature an IR sensor to be used by a Palm
for automated dialing.

Re: [Asterisk-Users] Asterisk fault tolerance and a embedded hardware solution.....??

2004-03-05 Thread Kiss Karoly

Hello,

IMHO you have a problem with the hardware that Asterisk runs on.
You should really look around because there are a number of companies
selling intel based systems with a cPCI bus fully hot swap capable.
I think the only problem would be getting network adapters compatible with
* but then this is only a problem of drivers easily solved by a good
programmer.

If you test out Asterisk on a fully redundant box and you find problems I
think you'd be welcome to send in a patch to fix them so that * could
be used in enterprise computing instead of sending in a two page e-mail
with the problems we all know about !

Regards

Kiss Karoly

Has anyoone tried implement Asterisk as a hardware based solution similar to Soekris
firewall?

Asterisk fault tolerance: I ran across this posting about Asterisk
and here is some interesting thoughts to ponder

http://groups.google.com/groups?hl=enlr=ie=UTF-8oe=UTF-8selm=aca5dd1d9141c07addd9d3414e934380%40free.teranews.comrnum=14

Not blow anyone's ASTERISK bubble BUT,,,

Show me an Asterisk system that can:

1) Have a communication bus that can survive the removal of the CPU,
and
still have calls in progress that remain active until the calling
parties
hang up.

Difficult problem to solve. One would have to have some sort of
parallel network connection. Perhaps one could have a buffering or
cache solution.

The CPU problem could be solved by a blade server or failover.

2) I have yet to hear of any Asterisk box running a fully redundant
CPU
configuration. I bet this is possible.Especially with the newer hot
swap
cPCI bus systems and slave CPU cards. Even better if the chassis has
and
embedded H.110, or equivalent in LAN/memory, switching bus.

Yes could be solved.

3) A redundant configuration where either CPU can talk to the
communications
boards (T1/E1), and LAN interfaces. And which can address all boards
in the
system redundantly.

Sounds like a job for Infiniband or a platform that has a switched
crossbar architecture like IBM P-Series or Sun.

4) A redundant configuration that has either shared system memory
between
the CPU's, or at least table copies between memory that hold all
static and
dynamic call information.

5) A redundant configuration that can swap between system CPU's in
less than
20 seconds.

6) A redundant configuration that can synchronize on, and share one,
two ,
and more network clocking signals. Plus synchronize on a independent
stratum 3 or greater clock source.

7) And can support 1,000 or more endpoints (TDM and/or IP) without
choking
on it's own guts.

8) A redundant configuration that can synchronize on, and share one,
two ,
and more network clocking signals.

Well it's a lot to ask, but enterprise computing demands a lot.
