ADMINISTRATOR GUIDE
The J3 software and above supports
ISDN to H.323 Gateway.
Example with IVR:
The GW shall be configured to have an H.323
Dial In number 1.
Add Dialling Rule
Set 1. Type to IVR
Select 2. Bandwidth
Set 3. Number of Significant Digits to 0
Set 4. From Network Type to H.323
Set 5. From Prefix to 1
Set 6. To Network Type to ISDN
Leave 7. To Prefix empty
To call an ISDN endpoint with ISDN number
67141234 from H.323, dial 1 and enter
‘67141234#’ using DTMF.
Dialling rules for telephone connections are
set up accordingly, with Bandwidth set to
Telephone.
Example with IVR-TCS4
Your ISDN PRI number for Gateway usage is
67124000.
Add Dialling Rule
Set 1. Type to IVR-TCS4
Select 2. Bandwidth
Set 3. Number of Significant Digits to 8
Set 4. From Network Type to ISDN
Set 5. From Prefix to 67124000
Set 6. To Network Type to H.323
Leave 7. To Prefix empty
To call an IP endpoint with H.323 E.164
Alias 4020 from ISDN, dial the ISDN number
67124000*4020.
The notation to separate the ISDN number
from the extension by ‘*’ is only available
on certain types of endpoints. Consult the
endpoint documentation to find out if and how
TCS-4 is supported.
Using IVR instead
If you want to use IVR instead dial 67124000
and enter ‘4020#’ using DTMF.
H.323 to ISDN Gateway
It is also possible to configure an H.323 to
ISDN Gateway.
Example with DID
Your ISDN PRI number range for the Gateway
is from 67124000 to 67124050.
Your IP endpoints have the numbers (H.323
E.164 Alias) in the range 4000 - 4050.
Add Dialling Rule
Set 1. Type to DID
Select 2. Bandwidth
Set 3. Number of Significant Digits to 4
Set 4. From Network Type to ISDN
Set 5. From Prefix to 6712
Set 6. To Network Type to H.323
Leave 7. To Prefix empty
To call an IP endpoint with H.323 E.164
Alias 4020 from ISDN, dial the ISDN number
67124020.
The Order of Dialling Rule Matters
To be able to do “empty” incoming prefix
matching as the example above, this Dialling
Rule must be the first that is added to the
mapping rules database. If not, this rule will
match with any other prior added dial in rules.
If you want your IP endpoints to have numbers
in the range 94000 – 94050
Set • To Prefix to 9 instead
Examples with ISDN Gateway
Example with DID:
The GW shall be configured to have an H.323
prefix 0047.
Add Dialling Rule
Set 1. Type to DID
Select 2. Bandwidth
Set 3. Number of Significant Digits to 0
Set 4. From Network Type to H.323
Set 5. From Prefix to 0047
Set 6. To Network Type to ISDN
Leave 7. To Prefix empty
To call an ISDN endpoint with ISDN number
67141234 from H.323, dial the number
004767141234.
Setting the Gateway’s Dial In number to 0047
will make the Gatekeeper route all H.323 calls
to an E.164 alias starting with 0047 to this
Gateway.
This means that all other equipment has •
to be configured with an E.164 alias that
doesn’t start with 0047.
Exceptions to this rule are other Gateways •
to perform load balancing.
