Introduction

Here the general vPBX features can be managed and activated/deactivated:

• Defining the identity of the subscriber, e.g. which public vPBX telephone number shall be used as CLIP or if all outbound calls to the PSTN shall be anonymous
• Defining the maximal number of concurrent internal and external connections
• Defining the music on hold
• Manual switching of inbound call routing according normal/night/weekend distribution
• Defining IP subnet or a SIP profile which contains a list allowed IP subnets where VoIP devices are allowed to register to this user account
• Defining a SIP profile which contains a list allowed IP subnets where SIP devices are allowed to register to this vPBX

Limiting the Maximal Number of Concurrent Channels

This feature allows the vPBX administrator to limit the maximal number of connections within the vPBX. This may be useful when the IP network bandwidth to the internet provider is limited. Consider, even a vPBX internal connection needs bandwidth to the provider!

Limiting the maximal number of channels is done by configuring "Channels" .

The needed bandwidth per channel depends on the used audio codec:

• Codec G.711 : ca. 128kBit/sec; ISDN quality
• Codec G.726 : ca. 16 - 40kBit/sec; Good VoIP quality

Different connection scenarios need another number of channels:

• vPBX internal connection:

A → B: 1 channel

• vPBX internal to/from public telephone network connection:

A → B: 1 channel

• Call forwarding to internal or public destination connection:

A → B, Call Forwarding → C : 2 channels

• Call forwarding to VoiceMail Box connection:

A → B, Call Forwarding → VoiceMail Box : 2 channels

Manual Change of the Call Distribution "Normal/Day/Weekend"

With the feature "vPBX Call Distribution Normal/Day/Weekend" the vPBX can be configured to distribute incoming calls as follows:

"Normal" :

The vPBX distributes incoming call according the call distributions of the actual day time.

"Night" :

Upon activation the vPBX distributes incoming calls according the call distributions at 00:00 of the next day. The "Night" distribution scheme is automatically switched back to "Normal" at 24:00 of this day.

"Weekend" :

Upon activation the vPBX distributes incoming calls according the call distributions at 00:00 of the next Sunday. The "Weekend" distribution scheme is automatically switched back to "Normal" at 24:00 of the next Saturday.

The manual change of the distribution scheme can also activated/deactivated from any telephone of this vPBX with the Service 980:

Service 980 Call distribution normal/night/weekend:	*#-Code:	Remark:
Activate the "Normal" call distribution:	*980	Activated weekend call distributions are deactivated prematurely.
Activate the "Night" call distribution:	*981
Activate the "Weekend" call distribution:	*982

The provider may have defined another *#-code for this service. Check at your provider for the valid *#-code!

Assigning a Zone Profile for Configuring VoIP Devices

A Zone Profile for the vPBX is needed when VoIP devices, e.g. telephones, shall be configured out of the AdminCenter. The VoIP device must be assigned via the AdminCenter (see "Assigning VoIP Devices ").

A Zone-Profile contains the information how a VoIP device can contact the vPBX for registering and downloading its configuration file. The provider prepares the available "Zone Profiles" . Check with the provider which Zone Profile must be used. If no zone is selected, then the "Default" zone is used.

Limitation of the IP Subnet for the SIP Devices

With this feature it is possible to define an IP subnet where the SIP devices are allowed to register at this vPBX. Registration attempts from SIP devices out of other IP subnets are rejected.

The IP subnet is defined with the parameter "Network" . It is possible to configure several IP subnets separated by commas.
Example:

172.1.1.0/24,192.168.10.0/24

Limitation of the IP Subnets with a SIP Profile for the SIP Devices

With this feature it is possible to define a set of IP subnets where the SIP devices are allowed to register at this vPBX. Registration attempts from SIP devices out of other IP subnets are rejected.

The provider prepares the available "SIP Profiles" . Check with the provider which IP subnets are associated with a SIP profile.

Public Prefix of Dialing to the Public Telephone Network

The public prefix "0" is usually used for dialing out from a vPBX to a national or international destination. With the "Public Prefix" this prefix can be changed to another number or can be deleted.

If no public prefix is used, then it may be that certain numbers are not allowed for internal vPBX telephone numbers, e.g. "110" which is also an emergency number. Check with the provider which internal vPBX telephone number are not allowed if no public prefix is used.

SIP Authentication for the Public vPBX Telephone Numbers

Note	This feature is usually not available!

The SIP credentials "Authenticating Name" and "Password" for the public vPBX telephone numbers may be changed.

Note	This configuration is valid for all public vPBX telephone numbers of this vPBX!

Warning

If not handled with care it is possible that the connectivity is not working correctly! SIP devices using this SIP credentials must be reconfigured accordingly! Configured Line Key on SIP telephones must be synchronized! These values must be handled confidential. They open the possibility of misuse and may cause high connection cost!
