2008-01-24: LINUX Stable 3.2.3 Release

Fixed a small bug that occures  on some kernels/compiles due to in-lining.  This bug was introduced in 3.2.2 release.  Also updated Setup install script to install wan_aftup in /etc/wanpipe/util directory so that firmware updates do not depend on source release.  We are planning to remove all objects from /etc/wanpipe directory in to /usr/local/wanpipe by next release to better comply with Linux directory rules. change log...

2008-01-18: LINUX Stable 3.2.2 Release

Removed the need for Zaptel DCHAN Patch for zaptel 1.4 or greater.  This means that zaptel does not need to be recompiled after wanpipe installation for zaptel 1.4 releases.  DCHAN Patch is still used on zaptel 1.2.   Updates to front end MAXIM chip to gracefully recover in case of short circuit.  Updated wancfg_zaptel.  For full list of changes refer to change log...
  

2007-10-07: LINUX Stable 3.2.1 Release

Updated driver for 64bit 2.6.22 kernel.  The old 3.2.0 driver failed to load on the latest 64bit 2.6.22 kernel. Updated Zaptel chunk patch for Zaptel 1.4.X.  Zaptel chunk patch allows one to run zaptel in 8,16,40,80 chunk sizes drastically reducing interrupt load. Updated legacy drivers for 2.6.22 kernel.  change log...

The 3.1 drivers stream has now moved into the stable stream. No new features will be applied to this stream, only bug fixes and critical updates.   This release has updates to A200/A400 analog card where it checks for tip/ring voltage on startup which could cause no dial tone on startup.  The Setup installation script has also been update to auto-detect zaptel directory.   change log...

Minor update.  Contains old config support for A101-SH card.  Updated Kernel ATM support used to connect kernel atm stack to sangoma aal5 layer over all AFT cards. Added wancfg_tdmapi configurator used to configure wanpipe drivers for TDM API: used for custom TDM API development.  Updated SMG. change log...

Update to octasic hwec!  Turned off NOISE suppression option that can interfere with faxes on some lines. If you have faxing problems with 2.3.4-12 or 3.1.2 release or earlier this update should resolve your faxing problems related to the hwec.  change log...

New octasic hwec update that fixes high speed faxing and modem over hwec.  Previous hwec release were limiting the fax/modem speed to 26k. With this release faxes run at 33K and modems at 56K.  Adjustable ZAPTEL chunk size feature, ./Setup can configure Zaptel for 10ms chunk size, drastically reducing number of hardware interrupts.   Both beta and stable release have same changes.  change log...

A major bug fix for all AFT Maxim E1 cards for E1 CRC4 Mode. On some lines the E1/CRC4 mode causes line errors on the telco side which results in PRI not coming up. Furthermore new firmware V31 has now been released for All AFT Maxim cards that fixes a serious echo canceler problem.  change log...

A major bug fix for all AFT Maxim E1 cards for E1 CRC4 Mode. On some lines the E1/CRC4 mode causes line errors on the telco side which results in PRI not coming up. Furthermore new firmware V31 has now been released for All AFT Maxim cards that fixes a serious echo canceler problem.   change log...

This is a very minor release.  It only contains the new zaptel patch for 1.2.17 zaptel release and above. There are not driver changes.

This release contains hw support for new AFT 56K DDS card, AFT T3/E3 card.  Updated front end code for Maxim chips that will fix a bug on port shutdown. Updated patch for zaptel 1.2.17.  Analog network sync feature that will improve faxing between a digital and analog card. For more info refer to the change log...

This is a MAJOR Beta release that contains the hardware support for latest wanpipe cards: A101D A56K DDS etc...  This release also has 2.6.20 kernel support as well as RBS/CAS fixes for AFT MAXIM cards: A101d/2d/4d/8d.  The release nomenclature has changed please refer to the changelog for more info:  change log ...

This release contains support for A101dm (pci) and A101dmx (pci-e) that supports optional hardware echo canceler.  It also contains DCHAN patch for new zaptel 1.2.17. For more info please check the change log ...

This release contains important bug fixes on AFT TDM Voice (Zaptel) Drivers.  A potential race condition existed, on startup when hardware echo canceller is used.  If T1/E1 line came up fast enough, the zaptel could be left in alarm.  We have also relaxed LOS from T1 alarms, so that LOS hickups dont bring down the PRI.  CAS signalling has also been fixed for MFC R2. 

The RBS support is broken on all Maxim/Dallas cards: A102dm/4dm/8dm.  For working RBS support on above cards you will need to use new beta release 3.1.0.  For more known issues please check the known issues link.

The RBS support works for all PMC based cards A101/2/4d

For more info please check the change log ...

New release fixes a potential bug in AFT drivers.  This was also added in 2.3.4-5 release.  Unfortunately due to some critical updates in 2.3.4-5 a release was rushed and some new features crept into the release.  I have taken these new features out and will test them in the beta release.  New beta release will start shortly and the 2.3.4 release will remain frozen.

New release has a bug fix that was introducted in 2.3.4-5 release.
The bug affects ALL AFT hardware echo cancellation cards.  The pesistent echo option doesnt did not cleanly unconfigure the echo canceller, which would cause a wanpipe deivce restart to fail.  Read the change log for more info.

2007-01-26: LINUX: New Stable 2.3.4-5 Released

New release has number of minor but important bug fixes for A102/A108d/A102d/A301 drivers as well as LIP Layer WAN stack that affects all ports.  This release also has a new ZAPTEL/Sangoma configuration feature "/usr/sbin/wancfg_zaptel " that can be used to quickly configure sangoma cards for zaptel.  This release also has a persistent hardware echo feature.  Click here for more info.

New important A200/A400/A108D/A102D bug fixes in 2.3.4-4. Anyone that is using A200 or A400 analog cards with releases beta12-2.3.4 or greater must upgrade to 2.3.4-4 release. Click here for more info.

New important A200 Analog bug fix in 2.3.4-2.  The FXO sanity checker had a bug in it that could cause potential system instability on some kernels/systems.  Along with this important bug fix, wanpipemon A200 voltage stats have also been fixed. Click here for more info.

The official stable 2.3.4 package has been released. The new 2.3.4-1 release has incremental changes from beta12-2.3.4.  The new release has some A108 front updates, that caused some ports not to come up on certain lines.  It also has updated wanpipemon stats.  Click here for more info.

The Beta12 release has further updates for A200 analog drivers. It has more robust error checking code that prevents fxo/fxs hardware register lockups that cause incoming calls to be ignored during operation.  This occurance is very rare and only happeds on some lines.

New beta11 2.3.4 release has support for A102dm cards.  As well as major updates for A200 Analog cards.  We have added more robust register checking on A200 to combat fxs/fxo outages. Also we have added a special "wanrouter hwprobe verbose" option that will display all FXO/FXS modules installed.

The 2.3.4 releases will be going stable shortly!
