4.1 Call Control Flow
The route followed by a call entered in the multiSwitch equipment is different from call to call.
The call control flow depends on the calls type, if it is IP to IP, IP to TDM, TDM to IP, TDM to TDM or
IP/TDM to a special service. These cases are detailed below:
IP to IP case
Access In => Incoming Class => Optional DB checks => Routing table => Outgoing class =>
Access Out
TDM to TDM case
Incoming Class => Optional DB checks => Routing table => Outgoing class
IP to TDM case
Access In => Incoming Class => Optional DB checks => Routing table => Outgoing class
TDM to IP
Incoming Class -> Optional DB checks -> Routing table -> Outgoing class -> Access Out
IP/TDM to special service
Access In (IP case) -> Incoming Class -> Optional DB checks -> Routing table -> Service |
Hunting | Port
From the multiSwitch input trunk until multiSwitch output trunk, a call must pass through
several tables like Access In, Incoming Class, Routing Table, Outgoing Class, Data Base, Access Out.
Access In
Is used only for IP call (SIP/H323).
For TDM calls port is directly assigned to incoming class.
It assign an incoming class for each call according to:
- IP/netmask
- TCP/UDP port
- protocol (SIP/H323)
- Prefix
- Number of digits from DNIS
Incoming class
Each call has an incoming class
Settings from incoming class will be applied to the calls assigned to
it.
Optional DB checks:
- translate ANI
- translate DNIS
- portability
- ANI users
Here you can activate some optional database checks see bellow.
Routing table
It route calls to one of the following:
- outgoing class
- special service
- hunting service
- directly to a specific TDM port
Outgoing class
Settings from outgoing class will be applied to the calls routed to it.
Access Out
Is used only for IP call (SIP/H323).
For TDM calls port is directly assigned to outgoing class.
Specify the IP:Port, Protocol (SIP/H323) and
Transport(UDP/TCP/TLS) where the calls are sent.
Relation between Outgoing Class and Access Out is one to one
