Key points for Procurement and Return of TF/DID Numbers from/to Suppliers

How many TF/DID numbers should we keep?

IOD should update the last 12 months TF/DID numbers turnover days by destination in monthly basis to keep the numbers of TF/DID numbers in reasonable level.  The active date of each active numbers can be found in Numbers management as follow:

The analysis could be done after the export of the report to excel locally. 

Which suppliers should we keep/ procure?

In general, IOD should base on the ASR % to choose which supplier should we consider to keep/ procure for that particular destination. For example, since SMM provides the higher ASR %, IOD should consider SMM as priority for Macao.

For the below case, even PT. Indosat provide lower ASR % than PT. Taztel. However, since PT. Indosat is the tier 1 telecommunication company in Indonesia, IOD should keep/ procure the TF/DID numbers from PT. Indosat rather than PT. Taztel. 

Points to remember when different rate quoted (fixed, mobile and other rate) by supplier during number procurement

For service plan case, real number with different charge rate should have different routing number. IOD should inquire supplier for the routing number of each access type and notify provisioning team to prevent wrong rate used for relevant access type when calculating operating cost.
