Shaun,

Thank you for the reply.  I would suggest to move this conversation to
JIRA as we digressed from the original topic a lot.

https://issues.asterisk.org/jira/browse/DAHLIN-241?focusedCommentId=193920&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-193920

Thank you,
Vladimir

It is possible but not without more work. Asterisk would need to
parse the output of the memory map in /proc//maps and figure
out where the modules are mapped into the current process' address
space and then lock only those pages. Also, this would require
knowing exactly which modules are needed at first. Since Asterisk
really should be run in a soft real-time fashion, I still
believe it's preferrable to figure out which modules are needed and
then making sure all those pages can stay resident in memory.

You are correct. You will not be able to lock all the memory and one
of the allocations will fail if you're autoloading all modules. So
if you want to avoid delays incurred when the system needs to page
in code pages on events, you will either need to add more memory or
limit the modules that are loaded.

For example, when I disable autoloading, and only load a few modules needed
for a basic system only 153M is needed:

  # asterisk -rx 'module show'
  Module Description  Use

Benny,

Thank you for clarification.  I did not know executable pages would not
swap.

Shaun wrote a patch with mlockall() and it crashed my system badly.

Is there a way to lock just a specific module in memory vs. the whole
Asterisk application?

This is what the patch on DAHLIN-241 [1] is intended to do (only if Asterisk
is run in the real-time priority class)

[1] https://issues.asterisk.org/jira/browse/DAHLIN-241

What I feel is the important clue in this case is the problem, as
reported, only occurs after this system has been idle for awhile.

I just updated the patch since the memory locks weren't carried
through after the fork call.  When I apply the patch on the current
head of the asterisk 1.8 branch and load all the asterisk modules by
default:

  # asterisk -p
  # cat /proc/`pidof asterisk`/status | grep VmLck
  VmLck:567268 kB

You can see that just after load there is already 567MB locked.
The systems on DAHLIN-241 started with 384M and were updated to
512M.

Executables do not get written to swap, their pages just get discarded
under pressure, and reloaded directly from their original location on
disk.

The only way to ensure that Asterisk always stays in memory is to use
the mlockall() system call; doing that would require patching Asterisk.

Eric,

I sure did.  It is active for the last 18 months ever since I started
having this problem which coincided with my switching to Asterisk 1.8
from 1.6.2.x where I never ever had any of the DAHDI and / or
Asterisk-DAHDI problems I described before.

Eric,

Thank you for the suggestion.

In fact the problem is with FSX channel which fails to catch some DTMF tones 
from a phone which places an outgoing call.  Shaun's theory was a delay related 
to swapping.

I was assuming incoming DTMF detection.  Try toneduration=250 in chan_dahdi to 
increase the duration of transmitted DTMF on your DAHDI channels.  If that 
fixes it, try lowering it.  I find 80 usually works with even the worst IVRs.

Shaun, I respect your opinion, and the swap theory is one of the valid theories.

But interestingly enough, yesterday morning I had zero (0) bytes in the swap 
file and still experienced missing DTMF detection on an outgoing call.

I am not sure whether it is DAHDI or Asterisk specifically, well may be
one or both.

All I know is I opened support ticket with Digium, tried all their
recommendations, and I am still experiencing the same CID detection
intermittency.  Interestingly, in my case 2.6.0 was an improvement,
whereas 2.6.1 returned everything back to where it was before.

I still did not find time to file on JIRA, but I eventually will.

Here are the issues (not detailed, from memory):

 1. Incoming calls CID intermittency
 2. Lack of a dropped call detection where 45 seconds long voice mails
with CO generated bipping are left and the line is captured for up
to 3 minutes after a caller dropped a call when the IVR was active
 3. Intermittent outgoing DTMF drop
 4. CID flags are not being passed into dial plan for analysis, so we
cannot distinguish between private caller, no CID name, etc.

Eric,

I wish it were that simple as you described.

rxgain, txgain, cidrxgain, Digium support, Jira ticket, hours of
troubleshooting, hardware swaps, external power source, etc. -- all
these are the options I tried so far.

BTW, I did state that these specific issues are not limited to Digium
TDM410P cards.

Why do you believe it is a deficiency in DAHDI? The only issue that
I know of related to DTMF detection is DAHLIN-241 [1], which you
and I are currently trying to definitely establish is related to the
time it takes to page Asterisk pages back into memory, which isn't
really a DAHDI issue.

[1] https://issues.asterisk.org/jira/browse/DAHLIN-241

Also, the only recent CID issue I'm aware of which was related to
DAHDI was introduced in 2.6.0 and fixed in 2.6.1 [2].  This issue
was that the ring event was reported late to Asterisk, so Asterisk
would bump the gains in the middle of the spill. If the line quality
was marginal the callerid would be missed.

[2] http://svnview.digium.com/svn/dahdi?view=revision&revision=10473

Are there other issues with CID detection that you are currently
having? Generally CID issues aren't necesarily DAHDI related since
generation and detection is done in Asterisk and not DAHDI, like
DTMF detection (DTMF generation can be done in DAHDI...).

Cheers,
Shaun

In my experience when you have "intermittent problems with incoming caller ID, 
FXS -- with DTMF detection" you have to adjust your rxgain and/or txgain.  I am 
NOT a fan of Digium cards, but these CallerID and DTMF issues are simple and 
solvable and not related to the card itself.

Amit,

Make sure you have an option to return Digium TDM410P if it does not work for 
you.

In my experience Digium TDM410P produce substantial background noise on certain 
Dell computers.  Generic TDM400 do not have this issue.

On top of that  FXO channels exhibit intermittent problems with incoming caller 
ID, FXS -- with DTMF detection.  These two problems manifest themselves with 
both Digium and generic cards.  It looks like it is just a deficiency in the 
current DAHDI implementation.

Poor grammar on my part,

What I meant was to assign one ext to each IP Phone, my initial setup
consists of 5 phones. If all things work out as planned and after better
understanding I wish to support upto around 70 IP phones.

I do plan to get echo canceller too ;)

Thanks for the reply.

Although it was better to ask it in Asterisk commercial list but you have
different options like Digium, Sangoma or Openvox. TDM410P is the PCI one
from Digium which suits your description. Just remember to buy two trunk
(FXO) modules too and if you are looking for a best sound qulity get
hardware echo canceller too.

I just didnt get why your are going to set 5 ext on each IP Phone!!!
