 Have a look at asterisk-1.6.1 and module func_speex.so, which provides
AGC function. This function can be applied to any channel.  

 Documentation:
http://www.voip-info.org/wiki/view/Asterisk+func+speex
 and *CLI> core show function AGC

 Hope it helps
 Lukas

Re: [asterisk-users] Hangup extensions via CLI?

> asterisk -rx "soft hangup $(asterisk -rx 'core show channels' | grep SIP/7000


 Hi,

 I used this way of processing output from asterisk 1.2 and found out
that it is not 100% safe because there can appear unprintable characters
in the output. This will cause the following grep command to show
message similar to "Binary content: matched" instead of expected line.

 It is necessary to use "strings -a" to filter output. So your example
should be:

 asterisk -rx 'core show channels' | strings -a | grep SIP/7000



 Hope it helps

 Lukas

 Thanks for this detailed reply, amount of information exceeded my
expectation :)

 In dahdi_tool, there are three more indicators of error:
 IRQ misses
 Bipolar violation
 CRC error

 As I understand it now, these should be error counters and they provide
additional information in case of RED alarm state.

[asterisk-users] Description of Zaptel/DAHDI E1 alarms

2009-01-19 Thread Lukas Rypl

 Hello,

 I am missing any description of zaptel/DAHDI alarms. The TE200 series
user manual contains only a description of LEDs states. These alarms
states are visible in zttool/dahditool or in astersick CLI (zap show
status) and I wonder what is the real meaning of these alarms for E1
channel.

Possible alarm states (based on zaptel.h 1.2):
 1. No alarms
 2. Recovering from alarm
 3. In loopback (local loopback or far end?)
 4. Yellow Alarm (is it only "Far end Loss of Frame"?)
 5. Red Alarm (Loss of Signal?)
 6. Blue Alarm (AIS?)
 7. Not Open


 Thank you for any help.

 Lukas Rypl

[asterisk-users] Support of simple E1 CAS signaling (MFCR-like)

2007-09-13 Thread Lukas Rypl

I have a legacy device, which has multiple analog POTS lines and two E1
trunks with CAS signaling in 16th timeslot. It is in fact MFCR2
signaling without register signaling. Only the following link states are
signaled:

 TxRx
ABCD  ABCD
Idle1001  1001
Seized  0001
Seize Ack 1101
Answered  0101

ClearBack 1101

ClearFwd1001

Blocked 1101  1101


 I tried to connect it via Digium TE205p card to the Asterisk but I not
sure about the proper signaling. I started with MFCR2 and unicall
library, which has the same basic signaling, but it stops after the
first R2 signal is transmitted from Asterisk because it does not receive
any response (this is expected behavior). My first idea about simple
"disabling" register signaling in MFCR2 library was pretty naive,
because it is really complex piece of code.

 The question is: is there any signaling implemented in Asterisk, which
will work with this type of CAS signaling?

 Thanks for any help.

 Lukas
