• Are transparent to the system user because they perform like any other CO trunk in the
system.
• Reside in CO trunk groups like other trunks. SIP trunk calls can be routed using Auto-
matic Route Selection.
SIP gateway trunks support:
• Transferring trunks, putting trunks on hold, and connecting trunks to conferences simi-
lar to other CO trunks in the system.
• Making and receiving calls by any endpoint.
• Peer-to-peer (P2P) audio by IP phones.
• Dialing Emergency Call number sequences, such as 911 in the US and 999, 112, and
others in Europe.
The MP-104 does not support:
• Pause digits. These digits are used to program a Speed Dial number or other digit string.
• SIP registration, which is used for authentication purposes.
IP Single Line Adapter
The IP Single Line Adapter (SLA) provides an interface between the standard single line end-
point and a 10Base-T network. It allows you to make phone calls through the IP network. The
IP SLA has an Ethernet IEEE 802.3 10Mbps UTP interface. The IP SLA uses flash memory
and its software can be updated over the LAN.
ITP and SIP Supported Features
Users can access most features by entering a feature code using the endpoint’s dialpad buttons.
The following table shows the station features (and default feature codes) that are supported
for phones operating in ITP mode and SIP mode.
Support for some features varies by endpoint. For a complete list of supported features refer to
the appropriate user guide. For a summary of user guides and part numbers, refer to Table ,
"Phone User Guides" on page 6.
NOTE
SIP trunks do not support the Direct Inward System Access (DISA) or speed
dial features.
