DISA - Direct Inward System Access

DISA ()
Direct Inward System Access leaves out the people who call into the system and provides them with an internal dial tone.
DISA (password [context [callerid [mailbox [@-voice context ]]]])
DISA (file with a password, [callerid [mailbox [@-voice context]]]) provides a dial tone internal callers outside so that they can make calls as if calling from inside extension . Upon hearing the dial tone, an access code must be entered followed by the "#". If it is correct, the caller hears another tone, which is the system of dial tone and the caller can make and initiate calls.
[Caution] This type of access represents a serious threat to security and real and must be carefully considered and planned before use, but you should be used at all!
The option is a numerical code that access should be introduced to the caller to make calls. Following this syntax, all users on the floor using the same access code. If you want to allow access unsecured, enter the string "no password," instead of a real password.
The context option specifies the context in which it began the call is placed. If not provided, DISA () assumes that the context called disabilities.
The callerid option determines the number of mail (and the optional voice context) of a mailbox. If the mailbox containing new messages to the caller will hear a stuttered dial tone to indicate this.
Alternatively, you can use the password file to define multiple access passwords. Each line of this file can contain either an access code or a combination of an access code and a context, separated by the "|" character (pipe). If not specified the context, it is assumed disability.
If the caller is authenticated successfully with a valid access code, DISA () will start the call in the context specified.

Webdial with Asterisk
For Webdial to work with Asterisk, a web server that can handle CGI scripts, has to run on the same machine. When you click the OK button of the input box, a small popup window is created, in which the CGI script is run. It first closes the popup, then creates a call file that rings your phone and when you pick up the receiver, Asterisk connects you to the number you clicked on. Therefore it needs to know your extension number in addition to the number you want to dial. A sample shell script to achieve this is provided below, but this can be just as easily coded in Perl or PHP. It uses the query arguments, channel, from for the caller, to for the number to call, context and timeout to determine how many seconds to ring your phone. Some changes to the sample might be on order to make it work in your environment.

#!/bin/sh
echo -e "Content-type: text/html\\n\\n" # Close the popup
callfile=/tmp/`sed -e 's/[^0-9]//g' /proc/uptime`.call # Create a unique filename
eval `echo $QUERY_STRING|sed -e 's/&/ /g'` # Create variables from arguments
cat <$callfile # See here for callfile syntax
Channel: $channel/$from
Callerid: $from
WaitTime: $timeout
Context: $context
Priority: 1
Extension: $to
EOF
mv $callfile /var/spool/asterisk/outgoing


Make sure the script is executable for the user, your web server is running under. To test it enter something like
http://server/path/webdial.cgi?channel=SIP&context=default&from=123&to=4567890&timeout=15
in your browser, where channel is the channel your phone is connected to, context is the one for calling out, from is your extension, to is a number you want to dial and timeout the number of seconds, you want your phone to ring. If this works, you can create the bookmarklet.

Javier mira estos emails cortos..sobre Sangoma, Siemens, faxesHay muchas variables a ver, ademas de los problemas reales con los aparatos de fax (falta de papel, roturas, etc) y las limitantes actuales entre trixbox y la Siemens. Por eso creo, que seria muy importante tener un ambiente de pruebas..!!Y no pasar las penurias en el cliente como hoy...ademas de la falta de posibilidades por el tipo de conexion. ------------------------------Siememes HiPath 3550------------------------------------------------------No son los mismos valores que para Uruguay ojo!!Muy parecido a lo egregamos hoy al DryTek..!Estava tendo alguns problemas com uma Siememes HiPath 3550. Coloquei no indications.conf [br]description = Brazilringcadence = 1000,4000dial = 425busy = 425/250,0/250ring = 425/1000,0/4000congestion = 425/250,0/250,425/750,0/250callwaiting = 425/50,0/1000 ; Dialrecall not used in Brazil standard (using UK standard) dialrecall = 350+440; Record tone is not used in Brazil, use busy tonerecord = 425/250,0/250; Info not used in Brazil standard (using UK standard) info = 950/330,1400/330,1800/330stutter = 350+440 zaptel.conf defaultzone=brloadzone=br zapata.conflanguage=br sip.conf [general] country=br E resolvi o problema. ---------------------------Fax through Sangoma------------------------------------------------------- in our company we are trying to do this: Fax <--> Traditional PBX <--> Asterisk <--> PSTN In practice, we have put an Asterisk equipped with a Sangoma A102 (2 PRI ports) between our PBX ( Siemens HiCom) and the PSTN in order to have a VoIP network along the traditional telephony network. The problem is with the fax. We just want to send and receive faxes from/to our fax machine connected to the Siemens (without needing any interaction with our VoIP network, the faxes are sent to/received from PSTN). Unfortunately we are experiencing a lot of problems: the faxes not always work and when they work, it's likely to have incomplete pages. I know that faxing with VoIP is very troublesome, but maybe someone else is using a similar configuration and he found a good configuration or maybe has some hints to improve the results. We are using Asterisk 1.2.13.-------------------------Sangoma will detect the tones and disable echo cancel---------------------Incoming faxes, the Sangoma will detect the tones and disable echo cancel. To send outbound, you will have to add another trunk group, of one or more channels and disable echo cancellation and use that to dial out. Example (/etc/asterisk/zapata.conf)blah blahechocancel=yesblah blah group = 1channel =>1-20 blah blahecho cancel=nogroup = 2channel=22-23 So you would use for faxing specifically Zap/g2/ and it will use channel 22 or 23 but with echo turned off. Use Zap/g1 and it will use the first group of channels with echo cancel on (or whatever other parameters come before the group command)----------------------------------- ULAW ou ALAW ------------------------------------------------------Renato, FAX sobre VoIP é um negócio chato, nunca funciona 100%.Pense na possibilidade de colocar uma Placa FXS direto no seu Asterisk.DIGIVOICE -> ASTERISK -> FXS -> Aparelho de FAX.Assim pode ligar o FAX direto no Asterisk e não precisa converter sua chamada para VoIP e jogar na rede para o ATA, pois a latência,perda de pacotes e outros motivos influenciam diretamente no envio de FAX.Considerações,FAX e Multifuncionais modernas enviam FAX na velocidade de 33.6Kbps, enviando através de ATA / VoIP não vai funcionar.veja se consegue abaixar a velocidade no seu aparelho.Ative o recurso de correção de erro do seu fax (Se tiver)Lembre-se de sempre usar ULAW ou ALAW para envio de fax, se for outro codec com maior compressão não funciona.Certifique-se que está fixando o codec no sip.conf.Experimente desligar o cancelamento de echo do seu ATA, normalmente ele faz isso automaticamente ao detectar o sinal de fax, masé necessário forçar-----------------------------------T.38 support in Asterisk------------------------------------------The T.38 support in Asterisk 1.4 is only pass through. Asterisk is notan endpoint or gateway of any sort. It only works passthrough inSIP to SIP calls without chan_local or chan_agent involved. Both endpoints of the call will need T.38 support and have T.38enabled in sip.conf.Asterisk 1.4 as I see it is still a bit unstable and not ready forproduction use. Be careful out there.-------------------------------------------------------------------------------------------------------------------Podria seguir pegando Emails de Asterisk, trixbox y Siemens...pero no es el caso...Solo queria enviarte los que considere importantes..!! --------------------------------------------------------------------------------------------------------------------- "Nós somos o que fazemos no dia-a-dia.

por lo de "Pobres condiciones linea"Did you change the rxgain or the rx setting? I changed the rxgain from 0.0 to 20.0. I might make some more test calls, reducing the rxgain to see at what setting the incoming fax detection breaks. Might invoke ztmonitor as well.Are you using the rxfax module or have you changed to nvfaxdetect? This time around I was using the rxfax module only. One variation that I noticed with AAH 1.5 was: (no son Trixbox, pero vienen bien)Without NVFaxDetect-Internal SIP fax -> 666 = OK. Internal SIP fax-> 7777 = Failure (Does not recognise fax & dials my default test ext). Incoming PSTN fax -> AAH 1.5 = OK.With NVFaxDetect-Internal SIP fax -> 666 = OK.Internal SIP fax-> 7777 = OK.Incoming PSTN fax -> AAH 1.5 = OK.Now I understand what you mean by fax detection as distinct from fax handshaking/negotiation.How I sent the test FAXHere is my ztmonitor during sending. (I split the rx and tx onto separate lines to get around the wp formatting) and then during the reception of the Telstra fax report.SENDING A FAXpbx:~# /usr/src/zaptel-1.2.2/ztmonitor 1 -vvVisual Audio Levels.-------------------- Use zapata.conf file to adjust the gains if needed.( # = Audio Level * = Max Audio Hit )<----------------(RX)----------­ ------><----------------(TX)----------­ ------>######################* ########################*########################*########################*####################### *######################## *######################## *######################## *######################## * ######################## *##########################*RECEIVING A FAXpbx:~# /usr/src/zaptel-1.2.2/ztmonitor 1 -vvVisual Audio Levels.--------------------Use zapata.conf file to adjust the gains if needed.

First off, do not use any version over 0.0.3. I am using 0.0.3 on centos 4.5, asterisk 1.2.24 and freepbx 2.3 and it is working very well. One very important thing to keep in mind is that faxing over voip will only work reliably with ulaw or alaw and your internet connection MUST be able to sustain a constant data stream with low jitter. If your interested I have a shell script to install asterisk 1.2.24 and
freepbx-2.3 with rxfax and txfax on centos 4 and working on centos 5.
