Call bonding (PRI)
ISDN call bonding of up to 2MB (E1)
1.5MB (T1) on PRI connections
Down speeding support

Management
SNMP – multiple
HTTP – embedded web server

Call Routing
Built-in Interactive Voice Response (IVR)
Direct Inward Dialling (DID)
TCS4
Default extension for operator assistance
Flexible/configurable IP dial plan
RS366 signaling (Serial)

Encryption
