- Modification of “local” numbers:
- Number mask: (xxxxxxx)
- Modification rule for CdPN/Original CdPN: +7383$
- Modification of long-distance numbers:
- Number mask: (8[3489]xxxxxxxxx)
- Modification rule for CdPN/Original CdPN: 7$
- Modification of international numbers:
- Number mask: (810x.)
- Modification rule forCdPN/Original CdPN: ---$
Following the instructions, create a table of modifiers named “A-number to E.164 PSTN”.
Following the instructions, create two modifications of the A-number for calls going to PSTN.
- Modification of numbers 201-209 to numbers 7941001-7941009

Configuring the connection to the local network
Follow the instructions to configure TAU:
- IP address: 192.0.2.16
- Network mask: 255.255.255.0
- Gateway: 192.0.2.1
...
Since TAU does not have a built-in clock, time synchronization from an external server is required to use real time for monitoring and statistics. For automatic time synchronization via NTP with TAU, an NTP server located on the local network or on the Internet must be available. SMG-200 cannot act as an NTP server.
Follow the instructions to configure synchronization with the following parameters:
