[asterisk-users] analog phone digit delay

[Eric Wieling]

My example is not _X. it is _X   It is there to catch single digit misdials.    The only line in my example with a . is the _[24-9].  Which will match neither 3xxx extensions nor any numbers staring with a 1  Hence, no timeouts.  We can talk about this all day, but other PBX admins solve the issue with good dialplan planning like in my example.

They won't catch, no (because of priority), but they do match, which is enough to trigger the 3 second timeout instead of the 8 second.  So, if you pickup and dial 1, then you will only get 3 seconds (instead of 8) to type in the next digit before it considers it done.  The issue I am describing is compounded by the fact that the patter is _X. instead of _X but the core issue is the same - only getting 3 second inter-digit timeouts instead of 8.

The catch alls do not catch 1+ or 3+ calls.  Look carefully at it.  Therefore there will not be a delay.

Right, but when you type any of those, there's only a 3 second inter-digit timeout because EVERYTHING is a match of the catch-all.  There is no excessive delay, but instead a delay so short that I'm getting complaints.

If I implement your suggestion and change the code in the channel driver, then there would be an 8 second delay all the time, even when dialing a number like 3001, which IMHO is excessive (and what I was referring to in the previous post).

So, again:

my two options as before:

1) Have the timeout be so short (3 seconds) that users complain (but they get a fancy message).
2) The timeouts are reasonable (8 seconds), but when they're wrong the users get a busy signal (no fancy message).

Plus we can add a third option:
3) Alter chan_dahdi.c to increase matchdigittimeout to 8 seconds, then:  The timeouts on invalid extensions are reasonable (8 seconds), but timeouts are valid extensions are excessive (8 seconds), and we get a fancy message.


It's a shame that reasonable timeouts and a nice message are mutually exclusive.

This issue is simple dialplan management, which applies to any PBX.   This is something every PBX admin has to deal with.

Here is an example using 4-digit extensions in the 3xxx range and outside calls are dialed with a leading 1 so the PBX knows it is an outside call.   There should be no excessive delay when dialing extensions or PSTN numbers in the setup below.  Calls should match when the last digit is dialed for those calls.   For invalid numbers there will, of course, be a delay.

exten => _1NXXNXXXXXX,1,DoYourOutsideDialing

exten => _3XXX,1,DoYourInsideDialing

exten => _[24-9].,1,DoErrorHandling

exten => _X,1,DoErrorHandling

No, I understand - maybe I'm not explaining myself well.

Yes, I can change the source so that pattern-matched input delays 8 seconds instead of 3, but then the users have to wait 8 seconds for every number they dial (even internal 3 digit calls).  I think what I really want is for the catch-all pattern to not trigger the shorter timeout.  It seems to me that if 3/8 second timeouts are standard and a catch-all for fancy messages is commonplace, then the two should work together without too much trouble, but instead they are currently mutually exclusive.

I realize that a code change will be required to accomplish standard 3/8 second wait times AND be able to get a fancy message (I'll be submitting an issue to jira - I'm thinking add a special 'no pattern matched' extension like i or t).  For the time being, I have the catch-all disabled at the site and things are running smoother.

Thanks Eric for your help on this - you helped me to track down the cause of the issue and provided a work-around, which is much appreciated.

You seem to be confused.

If you want to change the dialing timeouts on Asterisk analog channels, then you need to change the source code.   Now your dialing timeout problem is fixed.  I did that about 10 years ago to handle slow dialing users on asterisk analog ports.

Then add a catchall pattern for bad numbers and your congestion tone is fixed.    done!

I imagine setting up a catch-all extension pattern is your best option.  That is what most seem people do.

Okay, so I is no good.  Does anybody else have a work-around for this?

"I" has the same limitations as dialplan timeouts, you have to be in a Background or WaitExten or similar for them to work.    These items are designed for IVRS.

It seems likely that this is exactly what is happening.  I'd rather not change the code though, but rather fix the dialplan.  I'm thinking using the 'i' extension would work just the same - would there be a reason to use a wildcard pattern match instead of i?
