7.2.3.2. Prefix number (enbloc dialling)
When enbloc dialling (also called "one-stage dialling") is used, the digit collection is done in
the ICX-500. The destination phone number is included in the INVITE message from the ICX-
500.
The directory number must be programmed in the ICX-500 directory table with Feature 81 and
Node = SIP Trunk node number. In the "Parameter 2" field you must enter the maximum
number of digits in a phone number.
When the prefix is dialled, the ICX-500 will wait for more digits. When the number of digits
specified in the “Parameter 2" is collected, an INVITE message is sent to the SIP device. If
fewer digits are entered, the ICX-500 will send the INVITE after a 3 second time out. You can
also terminate the digit collection by pressing the M-key. The INVITE message will then be
sent immediately.
Dialling examples ("0" is the prefix):
0 + 571234: Telephone number 571234 will be called
0 + 5712: After a 3 second timeout, telephone number 5712 will be called
0 + 5712 + M: Telephone number 5712 will be called

7.2.3.3. Integrated Prefix number
The directory number must be programmed in the ICX-500 directory table with Feature 83 and
Node = SIP Trunk node number. In the field “Parameter 2" you must enter the maximum
number of digits in a phone number.
When the prefix is dialled, the ICX-500 will wait for further digits. When the number of digits
specified in the "Parameter 2" field is collected, a call setup message is sent to the SIP device.
If fewer digits are entered, the ICX-500 will time out after 3 seconds, and the call setup
