72 VoIP Subscriber Gateways
Example2: (<8:7>123) – this record will correspond to dialed digits 8123, however
7123 sequence will be transmitted to the SIP server.
2. Tone insert into dial
For long-distance access (for city access in case of office PBX), it is common to hear a
ringback, that may be implemented by inserting comma in a sequence of digits.
Example: (8, 770) - after digit 8 a continuous tone will output when dialing number
8770.
3. Number dialling deny.
If at the end of pattern add symbol '!' the dialling of numbers corresponding to the
template will be blocked.
Example: (8 10X xxxxxxx ! | 8 xxx xxxxxxx ) - expression allows dialling only intercity
numbers and exclude international calls.
4. Replacement of number dialling timers values
Timer values may be specified for a complete dialplan, as well as for the specific pattern.
Character 'S' is responsible for 'Interdigit Short Timer' setting and 'L' for 'Interdigit Long
Timer'. Timer values may be specified for all templates in a dialplan if values are listed
before the opening parenthesis.
Example: S4 (8XXX.) or S4,L8 (XXX)
If these values are listed in one sequence only, they are effective only for this sequence.
In this case, a colon should not be set between timeout key and value; a value can be
placed in any part of pattern.
Example: (S4 8XXX. | XXX) или ([1-5] XX S0) - entry will call instant call transmission
when three-digit number starting at 1, 2, ..., 5 is dialed.
5. Direct address dial (IP Dialling)
Symbol '@', setted after number, means that server address, where call will be
transmitted will be setted next. We recommend to use 'IP Dialling' and receive and
transmission of call without registration ('Call Without Reg', 'Answer Without Reg'). It
may help in case of server failure.
Moreover, IP Dialing address format can be used in numbers intended for call
forwarding.
Example 1: ( 8 xxx xxxxxxx ) - 11-digit number, starting at 8.
