I have an installation that has analog phones connected via T1 channel banks.  I'm getting complaints from users that they will enter a partial number (eg 91213), then turn away to get the next few digits, and the system will start dialing before they have a chance to put in the rest of the dialing string.  Is there a way to increase this delay?  The only use these 4 dialing patterns:

Internal 3 digit numbers
91 XXX XXX XXXX   (for backwards compatibility)
9 XXX XXXX (also for compatibility)
XXX XXXX


I'm using the freepbx distro if that helps.  Asterisk 11.2.

Thanks,

-Justin

Have a look at the documentation of the channel bank. I guess some kind of overlap dialing is 
enabled, which is typically associated with a timeout value. chan_dahdi.conf also has entries 
like this.

The channel banks are Adtran TA-624's using ESF/B8ZS.  When a handset is picked up, I can see the offhook in the asterisk console, so it looks that the channel is immediately connected through the channel bank (not delayed until after digits are dialed), so it looks that overlap dialing isn't a factor and that asterisk has complete control.

As for options in chan_dahdi.conf, I simply can't find any that relate to this problem.  I have looked at the page here: http://www.voip-info.org/wiki/view/chan_dahdi.conf and the closest thing I can find is 'ringtimeout' which is obviously not what I want.  I would expect to see something like 'dialtimeout' or 'interdigittimeout'.

This also means that you should see the digits as they are dialed. When something times out you 
should also see a message why there was a timeout.
I am using ISDN for PSTN connections and where I live there must be some kind of overlap dialing 
enabled, otherwise P2P configurations don't work. With current DAHDI drivers I no longer need 
special settings to make things work (Wanpipe/Woomera was different), so I guess overlap dialing 
is enabled. Some SIP phones distinguish between "Overlap Dialing" and "Automatic Dialing", so 
your channel bank might also have something like an Automatic Dialing option with some timing 
value.

There is an "overlap" option in configs/chan_dahdi.conf.sample.

I am currently assembling an Asterisk box that has 48+2 analog channels (+ SIP + ISDN). If your 
problem doesn't go away I could tell next week what my system is doing.

Will 'show function TIMEOUT' help?

Asterisk does fine in a virtual instance. The key is finding hardware that
would
support more than just virtualization (i.e., SR-IOV).... Not sure if such a
card
exist.

Hi,

Although this is a repost from Asterisk biz, we would like to ask if
somebody may help us to develop a native Asterisk module using AQuA
technology for voice quality monitoring using the same web service AQuA
Meter is using.

Thanks,
Sevana Finland/Estonia

Hi,

We would like to offer you to learn about our new application that performs
scheduled voice test calls to a predefined
echo server and then uses our AQuA web service to evaluate the call quality.

We developed it because several VoIP service providers have inquired us for
a possibility to make test calls from local machines within
their customers? network.

A typical example is when you provide VoIP communications to a company that
rents its premises (including an Internet connection) in a
business center. In this case it is quite important to monitor voice call
quality from different computers in the office space to the
service provider?s server.

This is a cross platform (Windows, Linux, MAC) Java application and uses
our latest developments in waveform analysis to evaluate voice call
quality: http://www.sevana.fi/aquameter.zip

The setup is simple: our application calls the echo server (apparently
provided by the VoIP service provider), plays a reference audio and records
the playback from the echo server and can thus provide overall (both ways)
call quality analysis.

We are very interested to receive your feedback and feature wishlist. The
application is free.

Best Regards,

Sevana Oy/O?
Finland/Estonia
