On this page a physical interface (ISDN or FXS) can be configured for Gateway use. Number mapping may be configured to normalize the called and calling numbers for internal use. An interface may be registered to a gatekeeper. If this is configured a VOIP interface and routes are generated automatically.
General Configuration
Name | Name of the interface. This name is used for local administration only (e.g. it is display in the routing table) |
Disable | Used to disable the interface without deleting the config |
Tones | This configures the tone scheme for this interface |
Interface Maps
The number mapping on the interface can be either configured manually, or predefined mappings for ISDN Point to Point or ISDN Point to Multipoint interfaces can be used. If predefined mappings are used they can be edited the same way as manual mappings, but if they are changed they are not recognized as predefined mapping anymore.
Point to Point
With the use of a few parameters the Point to Point mapping maps between an external representation of the numbers using the type of number field and an internal representation using Unknown as type of number and prefixes.
Area Code | The prefix used to convert from a subscriber number to a national number |
Subscriber Number | The prefix used to convert from an extension to a subscriber number |
National Prefix | The prefix used to mark a number as National |
International Prefix | The prefix used to mark a number as International |
Point to Multipoint
With the use of a few parameters the Point to Point mapping maps between an external representation of the numbers using the type of number field and an internal representation using Unknown as type of number and prefixes. Three external numbers (MSNs) are mapped to internal extensions.
MSN1-3,Ext. | The external subscriber numbers and the internal extensions they are mapped to. |
National Prefix | The prefix used to mark a number as National |
International Prefix | The prefix used to mark a number as International |
Registration
The physical interface may be registered using H.323 or SIP. For the VOIP call the media properties can be configured.
Media Properties
General Coder Preference | The coder preference (Coder,Framesize, Silence Compression) to be used if a non-local media address is detected. If the preference is marked as exclusive no other coder is offered. |
Local Network Coder | The coder preference if a local media address is detected. |
Enable T.38 | Switches on Fax detection and switchover to T.38 |
Enable PCM | Enable the media to be connected using the local timeslot switch if the call is between physical interfaces of the same gateway. |
MOH Mode | Special mode to use a physical interface as Music on Hold Source. The media is one way only and multiple calls are connected to the same channel on the physical interface. |
