The public network access code is 8 when dialed by a subscriber.
The public network access code is 9 from or to endpoints.
For L2 are always 00.
For L1 are always 0.
For L0 is always none.
Public prefixes always match the prefixes defined by the country's public network operators:

Display Number Modification Use Cases - Calls between two SIP Subscribers
Display Number Modification Use Cases - Incoming Calls from a SIP Endpoint (public gateway) to a SIP Subscriber
Local Toll Table for incoming calls from North American Numbering Plan
Within the North American Numbering Plan (NANP) boundaries between area codes are not as clear-cut as in the rest of the world. To aid in determining whether numbers need to be dialed as local or national numbers, a local toll table needs to be used that will aid number modification in optimizing a normalized International number.
Display Number Modification Use Cases - Incoming Calls from a SIPQ Endpoint (public gateway) to a SIP Subscriber
Display Number Modification Use Cases - Outgoing Calls from a SIP Subscriber to a SIP Endpoint (public gateway)
For outgoing calls, the translation tables become important as well. To create the connected party number for a gateway that does not provide a connected party number, the translation result is taken and made dialable.
Display Number Modification Use Cases - Outgoing Calls from a SIP Subscriber to a SIP-Q Endpoint (Gateway/PBX)
