General Information
The NEC SL1100 SIP Trunks behave like some SIP User Agents (UA). UA is
the client application used with a particular network protocol.
The NEC SL1100 provides a maximum of 32 register IDs and can register
these IDs with any SIP server.
A maximum number of 32 SIP trunks can be used with the NEC SL1100
system. The maximum number of simultaneous VoIP calls is determined by
the number of resources available on the VoIPDB.
The NEC SL1100 can connect any SIP server over a NAPT router by one
static global IP address. The NEC SL1100 system supports a DNS resolution
access and a IP address direct access for SIP servers and supports the sub-
address feature with SIP trunk interconnection.
