4. Dialing Principles

4-1 Dialing Options

Dial the phone number which you want to call and press # to call out immediately. Note that if the

“

#

(pound)”

not dialed, the number will be called out after 4 seconds by default. The period between

number dialed and call out is named

“

Inter Digits Timeout

”

. (Configurable from

“

DTMF and PULSE

”

,

default=4 seconds, see page 50).

If the phone number matches the setting of the Digit Map, the phone number will be dialed out through

the assigned VoIP Service Provider according to VoIP Route Profile automatically.

4-2 Number Translation

Phone number is dialed by user. The system will check if the phone number is matched Digit Map Table. If

no matched is found from Digit Map Table, it will use the phone number to look up number translation of the

server set in VoIP Routing Profile.

4-3 Routing

To achieve maximum flexibility, the number dialed will be looked up in several tables defined by VoIP TA. If

no match is found from Digit Map Table, it will then look up the number from another table and to the

registered VoIP Service Provdier.

Routing Processing Flow

The routing after checking Digit Map Table may be vary. The routing accords with VoIP Route Profile. By

default, Phone Book is the first route of VoIP Route Profile. The second and third route is Server 1 and

Server 2. Server 3 is the last route. Each server has a dialing plan, i.e. number translation, table, and the

number will be translated according the dialing plan before dialing out. For default setting, the number look

up flow appears like:

Assume that the route of Default Route Profile is Server 2 as the first route, Server 3 as the second route

and Server 1 as the last route. The number look up flow appears like:
