Questions regarding new echo cancellation features...
I notice the zaptel Makefile option the mark2 option & KFLAGS+=-DAGGRESSIVE_SUPPRESSOR is now gone. Does simply adding these options still compile in a certain echo can - or is there an other method of activating a particular can. I have not had to update my machine that is connected to pstn for a while & I don't want to jump into echotraining without a way to quickly enable what has

modprobe -r ztd-eth locks up machine...
Hi, I have just begun working with TDMoE running between 2 fiber nics the dynamic span works great. In my main asterisk box's startup file I just 'modprobe tor2', then start asterisk. The zaptel, ztdynamic & ztd-eth modules all load by themselves when tor2 is loaded. If I stop asterisk then 'modprobe -r tor2' the tor2 module is removed but the other three remain. If I

Music on Hold - can it be done without mpg123?
I have been having periodic trouble with mpg123. I have tried .59r & .59s and perhaps others a while back and still get the 'broken pipe' and zombie mpg123s (although I think I saw something about a fix in the changelog) once and a while. Is it currently possible to configure moh to run directly on the wav files? Now-a-days hard drives are so big, why use compression at all (at least

sementation fault with mpg123
I'm still getting a sementation fault with mpg123. I have tried different parameters creating mp3s the last from cd audio ... lame -m s --resample 8000 -q 0 -a --cbr -b 32 and several versions of mpg123. I have always created 8000 hz outputs. I've got other * boxes that don't use moh that have been up for months. This one crashes every couple of days - the verbose output leading to a

AT&T T1 Cable Needed!
Hi, I just got a T1 interface for a AT&T (became Lucent) System75 (uses same cards as Definity). I would take a crack at making a cable but can't determine the pinout for a cable and it is not apparent from the board. Asking you guys makes sense as one of you may have one of these systems. The cable has a amphenol male D50 connector on one end and probably a rj45 on the other. I also

FAX over IAX
Hi, We are looking at consolidating our lines with PRI. This will allow the elimination of many fax lines. Some of them will be replaced with this type of config ... PRI * IAX * Channel-Bank FAX We will have daggressor suppressor enabled. Is anyone doing this and should I expect smooth operation?

T1 vs PRI
Hi, I'm buying an interface for my Toshiba DKT424 to connect to *. Initially it is a trial to route internal calls over our wan. Think of it as a tie trunk between 2 pbxs. I expect to get PRI from the telco our layout will be like this: telco_T1_PRI to * to various PBX or TDM or IAX to * to other pbxs My question is, is there benefits to connecting with PRI over a standard T1 within my

Youch! Painfully loud beep...
I just called 6610 from Zap/1 exten => 6610,1,Dial,Zap/1&Zap/2 (Don't try this with the handset pressed up against your ear) ...is this the call waiting indicator? Is it a file, can it be turned down - and does it get used anywhere else? These are both fxs ports. In zapata.conf changinging to callwaiting=no stops this. The text implies that this affects fxo ports. John This e-mail

4 line phone w cid recommendation?
Hi, I'm looking for 4 line phones that will see some heavy usage (they need to be tough) for office secretary/receptionists. Any recommendations? One additional consideration (not particularly for my current needs) is regarding the page/intercom feature that can be mapped to one of the analog ports - does anyone know of a 4 line phone that will do this? Thanks, John This e-mail was

Periodic crash - avoid this syntax...
I have a machine that crashes every so often. I believe the following macro is responsible (gotoif,$[${ARG3}] in particular). The macro works as expected: if ARG3 is defined - hop over assignment. But my hunch is that it gradually chews up memory. ; This macro is puts voicemail in an alternate mailbox (if ARG3 defined - otherwise Mailbox matches extension). [macro-stdexten] exten =>

Question for someone running hylafax off *.
Hi, I am setting up a hylafax server. From what I've read so far, hylafax supports CID numbers and names but currently does not support DID. I assume I can do something like this... [40faxDIDs] exten => _87[5-8]X,1,SetVar(CALLERIDNAME=${EXTEN}) exten => _87[5-8]X,2,Dial(Zap/g${hylafaxMODEMGROUP}) ...and use the CIDName variable in hylafax to route the faxes to the appropriate

VoiceMailMain skipping extension and password prompting
I would like to access VoiceMailMain2 skipping extension and password prompting if calling from a resource that has a mailbox defined. What variables can I use to retrieve the calling channel & calling extension (if it exists)? Here is what I'm trying to accomplish (of course ${CallingResourse.MailBox} is not a real way to retrieve this info)... exten =>

T1-PRI deployment questions...
I am ordering T1-PRI service from local service provider and have a few questions. Is there framing and coding considerations (or is it all one standard), if so what is best? How are calls routed based on DIDs - are these just dtmf tones passed after the call is picked up and treated as normal exten=> definitions?

Asterisk and Cisco Callmanager
Hi Guys I have just come from a customer that is looking to install 13 Cisco CallManagers into all their branches, (i tried to convince them to go *). They are looking for a voicemail solution. Now as Kinesis and Unity are way too expensive (apparently cisco is launching a cheap voicemail system too) I was thinking of installing * as the voicemail solution. Lots of goggling i have found

How to pickup incoming calls immediately?
Hi, I set up a t1 from my sys75 to asterisk. After much experimentation I got it to work as e&m wink start. If dialing the trunk access code from the sys75 (a 5 - this is stripped on the s75), asterisk picks up and provides dial tone immediately. Here is the problem, after about 3 seconds that line switches into s,1 of the default context. If I dial (5)1234 very fast - before the switch to

TDMoE implementation suggestions
I have a T400P in my main building M and am going to put asterisk boxes in two buildings A & B. I already have our wan on fiber running between the buildings (including some extra strands) and the distance is beyond straight Ti distance so I would need csu... to use copper. It occurred to me that I could use TDMoE - and it may be less costly. My assumption is that the best to avoid the

Bridged trunks stuck off hook.
Hi, I'm getting a situation where 2 of my trunks (loopstart pots) are occationally bridged together (3624 Newbridge channel bank - asterisk signalling=fxs_ks for trunks) and are staying off hook until I do a 'soft hangup' on one of them. When I listen on a butt set each of the lines are silent (or at least by the time I find them). I am guessing one of the end users isn't properly

Setting a minimum 'on-hook' interval?
A couple of weeks ago I posted a message entitled 'Bridged trunks stuck off hook' about a situation where 2 of my trunks (loopstart pots - but Centrex) are occasionally bridged together. It has occurred to me that what may be happening is that a line hung up by Asterisk might quickly be reused and if the time interval is right, the telco will interpret this as a hook-flash. Is there a way

IAX with dynamic echo cancellation - what do you think?
I've been curious how IAX has been working for users running without a jitterbuffer and no echo cancellation. In my particular installation, IAX2 traffic remains within a pretty high bandwith WAN ( - but busy as it is linking buildings in a school district). It seems that at most times, things could run quite nicely in this mode. The ability to dynamically disable echo cancellation when end
