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:

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:

• 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>
