Single dial peer is associated with each call leg. In dial peer, components such
as codec, voice activity detectection(VAD) and fax rate are defined. For voice
call, four dial peer like the above figure should be configured.
According to call leg, single call is made possible using the following two
types of dial peer.
POTS-is dial peer to define characters of PSTN network. Generally, POTS
dial peer connects particular voice port of local PSTN, PBX or telephone
and dialed string.
VoIP-is dial peer to define necessary components in connecting packet
network. It is IP address of Destination Ubigate iBG3026.
To connect voice call through packet network, both POTS and VoIP dial peer
are necessary.
Inbound and Outbound Dial Peers
Dial peer is used in both inbound and outbound call leg. The meaning of
Inbound and outbound is defined from Ubigate iBG3026 aspect. When call
enters Ubigate iBG3026, inbound call leg occurs. Outbound call leg occurs
when call exits from Ubigate iBG3026.
Both figure 37.2 and figure 37.3 are the cases to be applied to call
through packet network. If originating and terminating POTS interface
are in the same Ubigate iBG3026, it is sufficient with two POTS dial
peers.
