Because Kqueue is not available on Linux, this module will not compile or be available there. In fact, this is the only timing source currently usable on a non-Linux system.

Asterisk Timing Interfaces

As vahdi as the dahdi module is loaded, it will provide timing to Asterisk either through installed telephony hardware or utilizing the kernel timing facilities when separate hardware is not available.

This timing interface is only available on Linux systems using a kernel version at least 2. At the time of Asterisk 1.

This interface has the benefit of being very efficient, but at the time this is being written, it is a relatively new feature on Linux, meaning that its availability is not widespread. This method of timing was previously the only means by which Asterisk could receive timing.

Alternatively, you may have been directed to this document due to an error you are currently experiencing with Asterisk. Dhadi a bug Atlassian News Atlassian.

It has the benefit of being efficient, and if a system is already going to use DAHDI hardware, then it makes good sense to use this timing source. By default, Asterisk will build and load all of the timing interfaces. Even though internal timing is not a requirement for dahhdi Asterisk functionality, it may be advantageous to use it since the alternative is to use timing based on incoming frames of audio.

Historical Note Icon At the time of Asterisk 1. Asterisk includes the following timing modules:. Now that you udmmy Asterisk’s default preferences for timing modules, you may decide that you have a different preference.

Beginning with Asterisk 1.

If, however, there is no need for DAHDI other than as a timing source, this timing source may seem unattractive. Unfortunately, this is not the case. It may also be used when generating audio for playback, such as from a file.

Powered by Atlassian Confluence 5. Using internal timing prevents such unreliability. The only functionality that requires internal timing is IAX2 trunking. If there dandi no incoming frames or if the incoming frames of audio are from an unreliable or jittery source, then the corresponding outgoing audio will also be unreliable, or even worse, nonexistent.

Starting with Asterisk 1. As of the time of this writing, the preferences for the modules is the following: For users who are upgrading from Asterisk 1. These timing interfaces are “ordered” based on a hard-coded priority number defined in each of the modules.

Asterisk includes the following timing modules: If you receive an error message regarding timing not working correctly, then you can use one of the following suggestions to disable a faulty timing module.
