5i Series IP Phone Release Notes
Mandatory versus Optional Billing Codes
This release of the Aastra IP phones supports two types of billing codes:
Mandatory and Optional. The Sylantro server configuration determines which
type of billing code is used on the IP phones.
•
Mandatory billing codes
: Calls are not connected until the user enters a valid
billing code. The user dials the phone number. When prompted for billing
codes, user dials the billing code.
For example, suppose the IP phone user is using billing code 300, and dialing
the external number 617-238-5500. The IP user then enters the number using
the following format:
6172385000#300
Using mandatory billing codes, if the user is configuring a Speeddial number,
then they enter the number using the following format:
<phonenumber>%23<billingcode>
To use this format with the default dial plan terminator (#), the # sign required
by Sylantro as a delimiter should be represented as an escaped character by
using the sequence %23. The speed dial format for an external number that
includes a mandatory billing code becomes:
<phonenumber>%23<billing code>
•
Optional billing codes:
The user dials an optional billing code by dialing
*50, followed by the billing code digits. When prompted for additional digits,
user enters the phone number.
For example, suppose the IP phone user is using billing code 500, and dialing
the external number 617-238-5000. The IP user then enters the number using
the following format:
*50500#6172385000
If the user is dialing configuring a Speeddial number, then they enter the
number using the following format:
*50<billingcode>#<phonenumber>
