Conversion of the Sent A-Number and the Sent Connected Number
These numbers consist of two parts: the exchange number and the user’s directory number. For sent connected numbers, the conversion is performed on the user’s directory number.
The MX-ONE Service Node distinguishes between private and public destinations when the sent A-number is to be converted. In both cases it is the sent A-number, the TON, or the route directory number that can be converted.
Conversion of the sent A-number or TON is possible depending on the outgoing route and destination. However, this conversion can be done depending on the additional category defined. If the category is set, the sent A-number or TON can be converted depending on the outgoing route or destination specified. At the originating exchange, if the category is not set, then TON conversion is not possible, nor is conversion on the outgoing destination. At the transit exchange, if the category is not set, then it is only the route directory number that can be converted based on the outgoing route.
Conversion of the sent A-number and/or TON is also supported for calls to a SIP extension. For extensions there is no additional number conversion category, so this type of conversion will always be done if initiated.
Depending on sent A-number, the number and its TON can be converted.
The following types of number can be converted for a sent A-number by a MX-ONE Service Node:
- Unknown public number
- International number
- National number
- Network specific number
- Local public number
- Unknown private number
- Local private number
- Level 1 Regional number
It is possible to convert the directory number in two ways, one for sending it to the public network and the other for sending the number to the private network.
For a sent A-number and sent connected number, the MX-ONE Service Node can delete up to 20 digits and add up to 20 digits. The result of the conversion can be between 1 and 20 digits.
The sent A-number can only be converted in the originating and transit MX-ONE Service Node, and the sent connected number only in the terminating MX-ONE Service Node. The conversion of the sent A-number in transit exchanges is controlled by the outgoing destination Class Of Service (ADC). For conversion in the transit MX-ONE Service Node, see Conversion of the Received A-Number and the Received Connected Number.
