Call Groups and Hunt Groups Configuration

From SIPfoundry sipx, The Open Source SIP PBX for Linux - Calivia

A huntgroup is a virtual extension that triggers a calling sequence. If someone dials a huntgroup extension, sipX will execute a calling sequence programmed by the administrator. As a part of this sequence several real extensions can be called in a parallel or serial manner. The administrator has the option to specify how long each extension should be rung before moving to the next extension in the sequence.

The sipX system allows the addition of as many hunt groups as you like.

[edit] Configuration

To configure hunt groups go to the Hunt Groups screen and click on Add Hunt Group:

Enabled: The hunt group is only active if enabled using this check box.

Name: The name of the hunt group is similar to the User ID of a user and has to be unique. A hunt group can be called either using its name or its extension (e.g. sip:myhuntgroup@domain.com).

Extension: A hunt group has a numeric extension that has to be unique.

Configuring the Calling Sequence:

• Serial or parallel forking can be used. If set to "if no response" serial forking is used and the call is forwarded to the next extension once the current call times out. If set to "at the same time" parallel forking is used and both extensions ring at the same time. The call can then be picked up at either extension (the first device that picks up wins). Parallel and serial forking can be mixed at different stages of a calling sequence.
• Hunt groups can be hierarchically nested as another hunt group can be used as an extension in a calling sequence.
• The same user line can be called several times if desired as part of the same calling sequence.

Note: The hunt group sequence will be followed until at least one user on the list answers the phone or the end of the sequence is reached. With the exception of the last user, the call will never be directed to any of the user's voicemail boxes even if they have voicemail enabled. If the last user on the has voicemail permission enabled, the call will end up in this user voice mail. Otherwise the caller will get a busy signal.

You can easily create similar hunt groups by using the Duplicate button on the Hunt Groups screen.

Hunt groups are usable as soon as you press the OK button. You can temporarily disable a hunt group without deleting it if you uncheck the Enabled checkbox and press OK.
