Announce: TDM2400P Driver Change


Thank you for your support of Digium and Asterisk.

Yesterday, we identified a problem with the driver for the TDM2400P card when used with FXO port modules. The X400M was producing (and expecting) the audio signal at an abnormally high level, which negatively impacted the performance of the echo cancelers, both hardware and software. It also resulted in unusual audio artifacts when the actual signal was already at a high level.

The driver in our Subversion repositories of Zaptel (both 'trunk' and 'branches/1.2') has been modified to properly initialize the FXO ports to alleviate this problem. We encourage all owners of TDM2400P cards with FXO ports to update their driver as soon as possible, especially if they are experiencing audio quality and/or echo issues on the FXO ports. This updated driver will be part of the Zaptel 1.2.2 release as well, if you wish to wait for a tarball release.

Thank you again for supporting Digium and Asterisk!

Release: AstManProxy - New Version 1.13 Now Available

Hey folks --

Good news! Version 1.13 of AstManProxy is now available for download!

Several enhancements have been made, primarily dealing with robustness and also an attempt to add Mac OS X support.

-- AstManProxy 1.13 --

-Changed to read only /etc/asterisk/astmanproxy.conf and not ./astmanproxy.conf
-Added a 'connected' field so we don't try to write to servers which are not yet connected
-Exits when there are no servers able to connect
-Doesn't attempt to re-connect to a server if we get 'Authentication failed'
-Added a connection timeout by using connect_nonb
-Confirmed support for x86-64 processors (added -fPIC; Jennifer Hales)
-Added support for Mac OS X (Tested on 10.3.9); BSD may also work
-Aborts on old config file format (detects incomplete server spec)

I've had much of this code "in the can" for a few weeks now, but have been traveling quite a bit and unable to sit down and package everything up. Please review and let me know your findings!

The next step for Astmanproxy will be to get a branch setup in the Digium Subversion (SVN) repository, which I hope to do sometime in the next few weeks.

Best wishes for a happy holiday season to you and yours!

Announce: Pending Web-MeetMe Update

[New Features]
1. Added focus to the input textboxes on all pages, so there's one less mouse click on each page. Trivial, but something that would likely trip some users up.

2. Dynamic generation of year/month/day listboxes to prevent invalid date selection. The system still defaults to the current date, but changing the month or year will update the day listbox with the correct number of days.

3. Added 'Extend' and 'End Now' buttons to the monitor page. The 'Extend' button adds 10 minutes to the conference. I have not added an 'Add Seats' button, and am not sure how critical it is. I'd like to avoid interface clutter if possible.

4. Call history report. It is now possible to see who was in a conference and for how long. There might be a small issue with this feature, as I did not see a clean way to add a 'Back' button. At the moment the only way out of this view is to select a menu item from the left side selections.

This functionallity requires a patch to app_meetme to add duration statistics to the meetme_leave event. There are a number of options to accomplish this, but for my environment, this is the best.

It also uses a small PHP script that needs to be running to catch the manager events. The script is a little crude at the moment, and does not deal well if Asterisk not available (crashed/stopped/etc), but works fine under normal circumstances.

I can either make this feature optional and disabled by default, or provide my app_meetme patch (all ready in Mantis). I'd appreciate comments on which people would prefer.

Note: While I am at it, if there happens to be a PHP guru lurking, I'd appreciate any comments on cleaning up the code.

I should have the new package ready by the end of the week.

Release: AsterFax beta 5 - Sendmail Integration

AsterFax provides an email based Fax gateway for the transmission of faxes using Asterisk.

You can download AsterFax at:

The newly released Beta 5 introduces two new features and a number improvements to the configuration of AsterFax.

New Features:

Integration with SendMail/Postfix/Exchange Server etc via procmail
With the release of Beta 5 AsterFax now has two modes of accepting emails for faxing. The exiting mode where AsterFax acts as an SMTP gateway plus a new mode where AsterFax can be configured to monitor a directory where Mime encoded mail files are placed for AsterFax to process. The recommended method is to use procmail to extract the mail messages out of the mail server pipeline.

Audit trail
An audit trail is now written for every fax transmitted. The audit trail is written to logs/audit.log.

Improved Debugging
A number of new debugging options are now available via the AsterFax.xml file to aid it diagnosing problems with AsterFax.

AsterFax has now surpased 400 downloads and is now ranked 305th out of some 100,000 projects on sourceforge, which given that its has only been available for 6 weeks is an indicator of the strong level of interest in the product.

News: Asterisk::LDAP Update

Hello All

About six months ago I wrote to announce the release of my Perl module to manage Asterisk configuration in LDAP. I wanted to take a moment and send this follow-up to announce a newly updated version of Asterisk::LDAP, version 0.6.0.

This new release is a significant improvement over the 0.5 series.

Here's a quick summary of the new features:

* Serial Numbers: Contexts are now written with a serial number and are not updated unless the serial number is incremented. This allows for granular and guaranteed consistent updates. Because LDAP updates are atomic the administrator or any external dialplan manager needs only to update the serial number after making any changes to the dialplan to guarantee the new dialplan will be loaded in its entirety.

* API Simplicity: As mentioned above, the API has been dramatically cleaned up. Where before a number of calls were required to set up Asterisk::LDAP before getting any useful data out, only one call is required and three more optional calls can help the developer automate much of the configuration of the module. Also the internal data structures are made available to external programs at more points during the configuration generation so any kind of hooks or post-processing can be done more easily.

* New Output Formats: The developer may now choose to have Asterisk::LDAP simply read the information from LDAP or have it write the contents to a set of files. Future improvements may include support for returning a string containing the entire data output instead of files written to disk.

Thanks again,

News: Unicall for MacOS X

A new project to bring Steve Underwood's Unicall telephony driver abstraction library to MacOS X has been initiated. Unicall is a replacement for Zaptel, the default telephony driver suite for Asterisk on Linux. The Unicall for MacOS X project aims to support the following hardware:

# Motorola SM56 based Apple Modems, ie. internal and external Apple USB Modem
# Intel i537 softmodem PCI card
# Odin Telesystems interface cards
# cards from other vendors if equipment and sponsorship will be provided

The Astmasters Zaptel for MacOS X project will be shut down in favour of the new Unicall for Mac OS X project. The following is an excerpt from a posting by benjk to the astmasters driver development mailing list on December 15th, 2005:

[Subject: Zaptel is dead - Long live Unicall]
Unicall has got it all

In the place of Zaptel, I would like to establish a project to bring Steve Underwood's Unicall to MacOS X. Unicall is a replacement for Zaptel, which has got all the things which are absent from Zaptel ...
# Unicall has design.
# Unicall has structure.
# Unicall has abstraction.
# Unicall has documentation.
# Unicall has direction and a roadmap.
# Unicall has a cross-platform philosophy.
# Unicall has taken a multi-vendor-telephony-hardware approach.

Lucky Seven. What more could we possibly ask for?!

Announce: QueueMetrics 1.0 rc 1 Release Today


I am pleased to tell you that we have released a new version of QueueMetrics. This time QueueMetrics "comes of age", as we have almost reached version 1.0. :-)

This version is the result of a feature-freeze of version 0.9.7, and vastly improves memory efficiency, letting you analyze as much as two to four times the number of calls using the same amount of RAM. QueueMetrics is strongly focused to serve the largest commecial call-centers based on Asterisk, and is very often being installed on 100+ agents systems.

Pause handling was improved in order to support even the weirdest cases of agents pausing in/out when not logged on.

We are confident that you'll love this version!

A complete list of improvements can be found here:
The latest version of QM can be downloaded from:

QueueMerics is free to use and experiment for smaller call centers, home users and general Asterisk hackers. Larger installations can ask us for a free trial key from:

Project: Implementing Bluetooth Proximity Detection with Asterisk and a TomTom GPS

We've pretty well documented how you can set up Bluetooth Proximity Detection using a bluetooth headset or cellphone with your Asterisk PBX. Once configured, phone calls in your home or office can automatically be transferred to your cellphone whenever you take off carrying your bluetooth device. In our original articles, you'll recall that we recommended a bluetooth headset as the ideal way to track your comings and goings at very little cost. But today, we want to add another bit of magic to the project and also give you something to tell Santa about.

News: VoIP Providers ignore FCC E911 order

Trixter has posted an interesting follow up to the FCC e911 order.


"Under the FCC mandate, VoIP providers shouldn't be marketing their service to customers in non-E911 areas; initially, the FCC wanted to force providers to stop service to existing customers as well as stop marketing. According to media accounts, companies such as 8x8 are waiting for the FCC to respond to their final E911 filings due on the November 28th compliance deadline so they can get clarity on what service will suffice until they can implement a full E911 solution.

A few research firms believe the FCC will not enforce strict compliance with the order so long as VoIP providers demonstrate forward progress in ultimately meeting the E911 service requirements. And the FCC may intentionally take its time in getting around to handing out fines because of Congressional interest in the matter. Bi-partisan groups of Senators and Representatives have expressed their concerns in a rush to implement E911 due to the lack of staff support and potential for "competitive third-parties" - ILECs - to intentionally hinder the implementation of E911.

Announce: VoIP Recording App


For those of you interested, there is an open source project that does VoIP recording, database CDR storage and web retrieval.

It supports raw RTP, SIP and Cisco Skinny (SCCP) by packet sniffing and runs on both Linux and Windows.

Interesting if you don't want to have asterisk manage the call recording itself (e.g box has high load, want to make it more reliable).
