Multi-Stage Digit Collection (Billing Codes) Support (for Sylantro Servers)
The IP Phones support Multi-Stage Digit Collection (billing codes) for Sylantro Servers. Sylantro
Server features, like mandatory and optional billing codes, requires that the application server
notify the phone to collect more digits before completing the call. The IP phone is able to collect
digits in two stages to support the billing code feature.
Aastra IP Phone users are prompted to enter the correct billing code when they dial these numbers:
• External numbers.
• Eternal numbers dialed using a Speed Dial key.
Billing Codes Implementation Notes
Note the following implementation information:
• IP phone users may enter a 2-9 digit billing code. Billing codes may not start with either 0
(Operator) or 9 (external calls).
• When using Sylantro Click-to-Call, IP phone users select a billing code from a pull-down
menu.
• When placing a call, a secondary dial tone alerts IP phone users to enter the billing code. The
IP phone UI also displays a “Enter Billing Code” message.
• If an IP phone user redials a number, they do not have to re-enter the billing code. The billing
code information is maintained and processed accordingly.
• If an IP phone user enters an invalid billing code, the call fails.
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 Speed Dial number, then they enter
the number using the following format:
<phonenumber>%23<billingcode>
