Automatic M key on global group calls
Global Group now uses the auto_m_key flag from the related local group
M-key use on outgoing handset operated SIP calls
If calling out on a SIP trunk and using handset, the use of M-key could result in reset.
Line Echo Canceller (LEC) not started
LEC missing in two situations: 1. When calling from "SIP as station" to analogue station using handset. <br\> 2. Dialing AlphaNet area code, then lifting handset, then call directory number did not start LEC thus echo on the AlphaNet link.

Force all AlphaPro configuration to be done on local connection to the node. (Avoid unintended configuration from remote AlphaNet links)
ex_profile.flags.local_AlphaPro = 1
New 4 digit software version system
Now possible to do updates on release version.
Log System (Syslog)
<br\> The logging is handled by the syslog-ng log daemon. This can be configured to route the logs to different media. The log can be stored on on-board flash, or sent over the network with different protocols.
Known Issues
Large log files on on-board FLASH
The log is stored on a limited sized Flash partition by a file system. Routines to handle larger log amounts, like automatic clean up of older files have been implemented, but we still experience problems if the log rates get to large. These problems occur before a theoretical log rate versus free space analysis, mainly because of file system issues with a small number of available flash sectors. This file system factor makes it difficult to make an accurate estimate of handled log rates so the following is based on experience:
Limits:
Log rates lesser than 1440 events a day (an average of one each minute) should be handled with no problem. Log rates of 17280 events a day (one each 5th second) is experienced to give problems.
Guideline:
If you are above 1440 events a day you should evaluate to use the Remote Syslog option, and turn off the Local Filesystem Log. If you are closer to the 17280 events log rate we strongly advise to use only the Remote Syslog option. If your system are logging above the 1440 events a day to the filesystem you should regularly monitor the logs.
Note:
From AlphaCom 10.23 a log limiter on the System and Debug log is implemented, allowing for a maximum of 60 events a hour. If this limit is reached, it will be notified by a log message. Because of this limit the above guidline will only apply to the Statistics log.

Version 01.10: 2008-01-16
Optimized codec processing. Each codec type has now variable number of channels, sum is always 32. Controlled by structures set up from dsp_drv. Also optimised DTMF generators, units 0400-040f.
Bottom line is that 32 channels is now working, with headroom for further development.
Requires dsp_drv version 02.10 / 01.10
Version 01.06: 2007-12-10
Full version with Line Echo Cancellation (LEC). 10 LEC-instances. (LEC processing moved to DSP#2, allowing 32 codec instances in DSP#1).
Version 01.05: 2007-11-20
Customer specific variant with Line Echo Canceling (LEC). Based on OSLEC. 6 channels of LEC, number of codec channels (G711/G722) reduced to 6.

Known problems AMC hardware 8000/2
Issue 2747: RCI not supported on ACE7:
RCI not supported on ACE7. The RCI signals on P1-c19 and P1-c22 are terminated in test points on AMC-IP. <br\>
Issue 2741: Redundancy control from APC:
The redundancy control system from APC is not working (software and hardware).<br\>
Issue 2787: AMC serial port: No RX, no data on TX:
It turns out that the RS232-drivers on the AMC-IP-board have an automatic shutdown when it detects missing received data (illegal voltage levels). This will be fixed in future hardware version, but it can be fixed on current hardware by a minor modification. Remove R698 and R695. The pins must be connected to Vcc (3,3V). <br\>
Issue 2806: “Temperature Alarm" in ACE.7:
This problem is probably related to the fact that the AMC-IP board never had a connection to the over-temp. signal from the ACE7 backplane. This is related to the problems with RCIs from the same backplane.
AMC Filter board
Issue 2723: RS422/RS485 Signal Pinning:
The pin out for RS422 signals on the filter print for E20 and E26 differs from the pin out on the E7. The Rx+ is switched with the Rx- and the Tx+ is switched with the Tx-. The only consequence is that the same cable can't be used on E7 and the E20-series. From filter print version 3 (DB8001/3) the mapping is correct.<br\>
