This is the Hangup application, which simply hangs up the current channel unconditionally. When an incoming call reaches this rule and matches extension number , the Goto application sends control of the current channel to extension sp with priority 1. When an incoming call reaches this rule and matches extension sp , a sequence of two events is triggered, starting with the Dial application, which is used to connect together all of the various channel types in Asterisk. Asterisk has its own set of modules that, among other things, support the various channel types. Multiple lines like this can be included, each for a different tonezone. In this case everything was detected correctly on the first attempt. A span is a logical unit that represents a group of channels.

Once the new dial plan has been saved, submit the changes to the running Asterisk process with this command:. When an incoming call reaches hfc s pci a 2bdso isdn rule and matches extension spa sequence of two events is triggered, starting with the Dial application, which is used to connect together all of the various channel types in Asterisk. When the zaptel-modules package was compiled and installed, a number of extra modules were added to the running kernel, such as ztdummy.
Prevents international calls from being missed because the dial plan is missing a variation of the phone number associated with this channel that includes two leading zeros follow by the country code and the area code. Spans are identified by incrementing numbers starting with hfc s pci a 2bdso isdn. It is possible to reload the Zap channel module on the fly, but that will not reconfigure all of the options.
In addition, there are also some other modules that can conflict with the required Zaptel modules: In this case the command is:. Use this command to show which Zaptel modules are currently loaded:.

To reconfigure hfc s pci a 2bdso isdn Zap channel, Asterisk needs to be restarted. This is a script that is used to generate a new Zaptel configuration file. The installation procedures below assume that an HFC-S PCI card has already been installed and that both the operating system and Asterisk are up and running. This frequently complicates matters, first of all because zaphfc. The value used here is arbitrary, but must be matched in the dial plan.
Sets the span number. It can also be used to combine two 64 kbps data connections to form a single kbps connection, but this has become less interesting since the advent of cheap, broadband Internet access.

This article describes how to configure Debian 5. The default is us. LAPB, however, is irrelevant for Asterisk, because when the B-channels are used for voice they carry no signaling at all: This event is hfc s pci a 2bdso isdn triggered by calls that reach this point and if the dialled number matches ” With digital telephony, a span usually represents a physical port on the card.
First, simply delete the buggy zaphfc module to ensure that only the correct one is used:. The name specified here, which is arbitrary, determines where incoming calls will enter the dial plan when they arrive on this channel definition.
Loads the indication tones dial toneetc. Asterisk has its own set of modules that, among hfc s pci a 2bdso isdn things, support the various channel types. Also called bipolar, this is a synchronous clock encoding technique in which binary 0 is represented by the absence of an electrical charge, while binary 1 the mark is alternately represented by positive and negative charges.
The first span is numbered “1” to make it the primary timing source on the system, accepting timing from the telco. Active cards handle most of the ISDN signalling information with hfc s pci a 2bdso isdn microprocessors and firmware, which is efficient when many channels see heavy use, but it also makes the cards much more expensive.
For all other numbers the catch-all rule will apply and the SIP channel will be used. Defines the channel or range of channels. In countries where the telco decided long ago to use some unusual version of this protocol, many popular telephony solutions various SIP adapters, Asterisk, etc. This is also why it is necessary to specify a line coding scheme for the B-channels. Although the command may be followed by specific span numbers, by default ztscan prints out information on all available spans.
Here, local is used, but unknown is also sufficient. This is in addition to SIP calls for extension
