Incoming ISDN Call S08 unit

Incoming ISDN Call S08 unit

I am installing an s08 unit onto a ipoffice 406,  I want to be able to hang a router of one of the s08 ports and have a remote device call into it so need to allocate a DDI number to go to the so8 port.

Is it as simple as creating a dummy user and mapping the DDI to user and user to the port ID, or is it more complex.

RE: Incoming ISDN Call S08 unit

Example Configurations
To route incoming calls on, eg. DID 123456 to the first port, eg. Line Group ID 701:

Configure an Incoming Call Routing:
The destination (type this in) represents the short code to be used to direct the call to the correct line group ID. Note that the Bearer Capability has been set to Any, to allow data and voice via this route.

Line Group ID: 0

Incoming Number: 123456

Destination: 123456

Bearer Capability: Any

Create a System Short Code:
This matches the destination in the Incoming Call Route.

Short Code: 123456

Telephone Number: 123456

Line Group ID: 701

Feature: Dial

Send the configuration to the Control Unit.


Any call coming into the main system on DID 123456 will now be passed directly to the first port.

If you wish to assign DID's from your main pool to individual ports and avoid network charges when dialing between them try variations on the following:

You have DID ranges, eg. 7325551000 to 7325551099. You wish to assign 7325551000-19 to port 1 and 7325551020-20 to port 2 etc.

Configure Incoming Call Route:
The # is used here instead of "n" to avoid problems with, eg. "Main". The minus sign means the number is processed from the left and so will wait for the whole number.

Line Group ID: 701

Incoming Number: -100x

Destination: #

Repeat for Line Group ID 702 etc.

Create Short codes, eg.

Short Code: 100x

Telephone Number: .

Line Group ID: 701

Feature: Dial


S0 calls dialed without the area code are handled locally without network charges. Calls with area calls will go via the network.
